How to Choose the Right Multispan Temperature Controller for Industrial Applications

Sat, 19 Sep 2026 06:36:22 +0000

Multispan Temperature Controller Selection Guide

A temperature controller is often purchased when there is a very practical problem to solve.

An oven may not be holding the required temperature. A heater may be overshooting the setpoint. A packaging machine may need more stable heat control. An existing controller may have failed and the maintenance team needs a replacement. In another case, an OEM may be designing a new machine and needs to select the right controller from the beginning.

In each of these situations, starting with a model number is usually not the best approach.

The better method is to first understand the application. You need to know which temperature sensor is being used, the required temperature range, whether PID or ON/OFF control is suitable, how the heater or cooling load will be switched, what panel size is available and whether alarms or communication are required.

Radical TechMart currently lists several Multispan temperature controller families, including compact TC series controllers and multiple UTC universal PID controller variants.

The purpose of this guide is to help you understand what to check before selecting the final Multispan controller.

What Does a Temperature Controller Actually Do?

A temperature controller receives a signal from a temperature sensor, compares the measured temperature with the required setpoint and then operates an output to control heating or cooling.

A typical control loop looks like this:

Temperature Sensor → Temperature Controller → Relay / SSR / Contactor → Heater or Cooling Equipment

For example, consider an industrial oven that needs to operate at 180°C.

The sensor measures the actual oven temperature. The controller compares that reading with the setpoint. Depending on the difference, it decides whether the heating output needs to remain active or reduce its control action.

This is why a temperature controller is not simply a digital display. Its main job is to maintain the process temperature around the desired value.

Start With the Temperature Sensor

The first thing to confirm is the sensor connected to the controller.

This point is often overlooked during replacement purchases. A controller may look physically suitable, but if its input does not match the installed sensor, it will not work correctly.

Common inputs in Multispan temperature controllers include:

J type thermocouple
K type thermocouple
PT100 RTD

For example, the Multispan TC 49P supports J, K or PT100 input options. It also supports PID and ON/OFF control, with relay or SSR control output depending on the configuration.

The Multispan UTC 413P provides selectable J, K and PT100 inputs in a 48 × 48 mm format.

Before ordering a controller, confirm:

Sensor type
Required temperature range
Number of sensor wires where applicable
Existing wiring
Sensor polarity for thermocouples
Whether the controller input is fixed or selectable

If you are replacing an old controller, do not identify the sensor only from the old controller's display. Check the wiring, sensor label or machine documentation if available.

Fixed Input or Universal Input?

Not every application needs a universal temperature controller.

If a machine always uses the same K type thermocouple and the same temperature range, a simpler controller may be perfectly suitable.

A universal controller becomes more useful when the same machine platform may use different sensors, or when the panel builder wants flexibility for different applications.

For example, the UTC 413P allows the user to select J, K or PT100 input and supports PID, time proportional and ON/OFF control.

More advanced Multispan universal controllers support a wider range of sensor inputs and additional control functions. The UTC 4204A M1, for example, supports J, K, R, S and PT100 inputs, along with multiple relay outputs, analog output and RS485 Modbus communication.

The main point is simple.

Do not select a universal controller only because it has more features. Select it when the application genuinely needs that flexibility.

PID or ON/OFF Control?

This is one of the most common questions when selecting a temperature controller.

Both control methods can operate a heating system, but they behave differently.

ON/OFF Control

ON/OFF control is relatively simple.

When the temperature moves beyond the selected switching condition, the controller turns the output ON or OFF.

This type of control can work well where small temperature fluctuations are acceptable and the process does not require very tight temperature regulation.

Typical examples may include simple heating applications where precise temperature stability is not critical.

PID Control

PID control is used when better temperature stability is required.

Instead of only switching fully ON or OFF around the setpoint, PID control adjusts the control action according to how the process is responding.

This helps reduce excessive overshoot and improves temperature stability in many heating applications.

The Multispan TC 49P supports both PID control and ON/OFF control, while the UTC 413P also provides PID, time proportional and ON/OFF modes.

For ovens, furnaces, extrusion machines and other thermal processes where stable temperature is important, PID control is often worth considering.

For a basic switching requirement, ON/OFF control may be sufficient.

The application should decide the control method.

Relay Output or SSR Output?

After selecting the sensor and control method, the next important question is how the controller will operate the load.

Two common choices are relay output and SSR drive output.

Relay Output

A relay output provides physical switching contacts.

Depending on the control circuit, the relay may operate a contactor or another electrical load within its specified rating.

Relay outputs are widely used, but the contacts are mechanical. If the application requires very frequent switching, the switching frequency and relay life should be considered.

SSR Output

An SSR drive output is designed to operate a compatible solid state relay.

This type of output is useful where frequent switching is required, particularly in PID controlled heating systems.

The Multispan TC 49P is available with relay or SSR control output options. Its datasheet lists a relay output and a 12 V DC SSR drive output.

The UTC 413P also provides relay or SSR output options depending on configuration.

One important point should be remembered:

Do not assume the temperature controller should directly switch a large heater.

The heater current, contactor, SSR rating, cable size and protection arrangement should be checked as part of the electrical design.

Check the Panel Size Before Ordering

Panel dimensions become especially important during replacement work.

A controller can have the correct input and output, but if it does not fit the existing panel cutout, installation becomes more difficult.

For example, both the Multispan TC 49P and UTC 413P use a compact 48 × 48 mm front format with a 45 × 45 mm panel cutout.

When replacing an existing controller, check:

Front dimensions
Panel cutout
Depth behind the panel
Terminal accessibility
Clearance for wiring

Do not select a replacement controller by front size alone.

The complete electrical specification should also match.

When Do You Need Alarms or Additional Outputs?

A basic application may need only one control output.

Other processes may require more.

For example, an application may need:

Heating control
Cooling control
High temperature alarm
Low temperature alarm
Auxiliary relay output
Analog retransmission
Communication with PLC or SCADA

The Multispan UTC 4204A M1 is an example of a controller intended for more involved applications. It provides multiple relay outputs, analog output options and RS485 Modbus RTU communication.

A controller like this makes sense when the process genuinely needs these functions.

For a simple heater with one sensor and one control output, a more basic controller may be easier and more economical to use.

Do You Need RS485 Modbus Communication?

Communication should be decided during the panel design stage, not after the controller has already been purchased.

RS485 Modbus can be useful when temperature values or controller settings need to be integrated with:

PLC
HMI
SCADA
Data acquisition system
Central monitoring system

The UTC 4204A M1 includes RS485 Modbus RTU communication for PLC or SCADA connectivity.

If the controller will operate independently and nobody needs remote data, communication may not be necessary.

Do not pay for communication simply because it is available.

Where Multispan Temperature Controllers Are Commonly Used

Multispan temperature controllers can be used in a wide range of heating and thermal control applications.

Common examples include:

Industrial ovens
Furnaces
Boilers
Packaging machinery
Plastic extrusion equipment
Injection moulding machines
Food processing equipment
Incubators
Heating systems
OEM machines
Industrial control panels

Multispan lists applications such as packaging machinery, extrusion machinery, furnaces, boilers, ovens, incubators and food industry equipment for selected universal temperature controllers.

The exact controller should still be selected according to the individual process requirement.

A Practical Example: Selecting a Controller for an Industrial Oven

Suppose an oven manufacturer says:

"We need a Multispan temperature controller."

That information is not enough.

A more useful requirement would be:

Sensor: PT100
Operating range: up to 400°C
Control requirement: stable heater control
Output: SSR drive
Panel size: 48 × 48 mm class
Power supply: standard industrial AC supply
Communication: not required

Now the selection becomes much easier.

The engineer can look for a controller that supports PT100, PID control, an SSR drive output and the required panel dimensions.

Now consider a second version of the same oven.

This version needs:

Heating control
Cooling control
High temperature alarm
PLC communication
Analog output

The original controller may no longer be sufficient.

A more advanced universal controller may be required.

This is why the application should come first and the model number should come last.

Common Temperature Controller Selection Mistakes

Common Mistake	Better Approach
Selecting only by price	Confirm sensor, output and control method first
Ignoring the existing sensor	Identify the thermocouple or RTD before ordering
Assuming every controller has PID	Confirm the control mode
Confusing relay output with SSR output	Check the actual load switching arrangement
Selecting by front size only	Check panel cutout, depth and wiring
Choosing a universal controller unnecessarily	Select features according to the application
Adding RS485 without a communication requirement	Plan communication only when needed
Replacing an old controller by model appearance	Compare complete specifications

Quick Selection Checklist

Before selecting a Multispan temperature controller, confirm the following:

What temperature sensor is being used?
What temperature range is required?
Is PID or ON/OFF control needed?
Is the output relay or SSR?
Is the controller being used for heating only or heating and cooling?
Are additional alarm outputs required?
What panel cutout is available?
What supply voltage is available?
Is RS485 Modbus communication required?
Is analog retransmission required?
Is the controller replacing an existing model?
Has the final model been checked against the official datasheet?

Which Type of Multispan Controller Should You Consider?

Requirement	Controller Type to Consider
Simple temperature control	Basic PID or ON/OFF controller
Known J, K or PT100 sensor	Fixed or selectable input controller
Different sensor types across machines	Universal input controller
Frequent heater switching	Controller with suitable SSR drive output
Heating plus cooling	Controller supporting both functions
Additional alarms	Multi output controller
PLC or SCADA integration	Controller with RS485 Modbus
Analog retransmission	Controller with analog output capability

Exact specifications vary between Multispan models and configurations. Always confirm the manufacturer datasheet before final selection.

Why Buy Multispan Temperature Controllers from Radical TechMart?

Radical TechMart lists a broad Multispan range that includes the TC 49P, TC 19 / TC 29 / TC 49 series, UTC 421P and several other UTC universal temperature controller families.

The important part is not simply finding a controller that fits the panel.

A better inquiry includes:

Sensor type
Required temperature range
PID or ON/OFF requirement
Relay or SSR requirement
Supply voltage
Panel dimensions
Existing controller details, if it is a replacement

With this information, it becomes much easier to narrow down the correct Multispan controller before comparing individual models.

At Radical TechMart, the focus should be on selecting the instrument according to the application rather than only according to the model number.

Final Thoughts

Choosing the right Multispan temperature controller does not have to be complicated.

Start with the process.

Identify the temperature sensor.

Confirm the temperature range.

Decide whether the application needs PID or ON/OFF control.

Check how the heating or cooling load will be switched.

Then confirm the panel size, power supply and any alarm or communication requirements.

Once these points are clear, selecting the controller becomes much easier.

In industrial temperature control, the right controller is not necessarily the one with the most features. It is the one that matches the sensor, process, output circuit and installation requirement correctly.

FAQs

1. How do I choose the right Multispan temperature controller?

Start with the sensor type, temperature range, control method, output type, panel size and power supply. Then check whether your application requires alarms, cooling control, analog output or communication.

2. What is the difference between PID and ON/OFF temperature control?

ON/OFF control switches the output according to the process temperature and setpoint. PID control adjusts the control action according to the process response and can provide more stable temperature control.

3. Can Multispan temperature controllers work with PT100 sensors?

Yes. Several Multispan controllers support PT100 input. Models such as the TC 49P and UTC 413P include PT100 options.

4. Should I choose relay output or SSR output?

The correct choice depends on the load switching arrangement. Relay output uses mechanical contacts, while SSR drive output is used with a compatible solid state relay and is often suitable for frequent switching.

5. What is a universal temperature controller?

A universal temperature controller supports multiple selectable temperature sensor inputs. More advanced universal models may also include additional outputs, analog retransmission and communication.

6. Can a Multispan controller connect to a PLC or SCADA system?

Selected Multispan controllers support RS485 Modbus communication. The UTC 4204A M1, for example, includes RS485 Modbus RTU connectivity.

7. Can I replace my old controller only by matching the panel size?

No. Panel dimensions are only one part of the selection. Sensor input, temperature range, output type, power supply and control function should also be checked.

8. What information should I send when requesting a temperature controller quotation?

Provide the sensor type, temperature range, control requirement, output type, power supply, panel size and existing model number if you are replacing an old controller.

A temperature controller is usually noticed only when something goes wrong: heater overshoot, unstable temperature, product rejection, relay failure, wrong sensor input, or a machine panel that no longer fits the replacement controller.

That is why choosing a controller only by display size or price is risky. In actual plant conditions, the controller must match the sensor input, output type, panel cutout, alarm requirement, power supply, communication requirement and control method.

The Honeywell DC 1000 Series is a general-purpose digital controller family covering DC1010, DC1020, DC1030 and DC1040 models. The official Honeywell PDF describes these controllers as microprocessor-based digital controllers available in four DIN formats: 1/16 DIN, 1/8 DIN, 3/16 DIN and 1/4 DIN. The series is intended for applications such as dryers, semiconductor packaging/testing, plastic processing, packaging machinery, painting/coating and climatic chambers.

What is the Honeywell DC 1000 Series?

The Honeywell DC 1000 Series is a family of panel-mounted digital controllers used for industrial temperature and process control. These controllers can handle common temperature inputs such as thermocouples and RTDs, and they also support linear signal input such as 4–20 mA depending on model configuration.

In simple words, this controller receives a process value from a sensor, compares it with the setpoint, and controls an output such as relay, SSR drive, analog output, SCR control or motor valve output depending on the selected configuration.

The PDF highlights important functions such as:

PID or ON/OFF control
Heat/cool control with two PID sets
Motor position control without slidewire feedback
Single-phase and three-phase phase-angle control
Zero-crossover control
Setpoint programming
Up to three alarm outputs depending on configuration
RS232 or RS485 Modbus RTU/ASCII communication option
Universal AC power supply from 85 to 264 VAC
Optional 24 VDC operating voltage

These features make the DC 1000 Series useful for machine builders and process users who need a practical controller for temperature regulation, alarm control and panel integration.

Honeywell DC 1000 Series Models

The PDF covers four main models:

Model	DIN Size / Panel Format	Practical Use
DC1010	1/16 DIN, 48 × 48 mm	Compact machine panels and small control points
DC1020	1/8 DIN, 48 × 96 mm	Vertical panels where larger display visibility is useful
DC1030	3/16 DIN, 72 × 72 mm	Mid-size panels needing better front visibility
DC1040	1/4 DIN, 96 × 96 mm	Larger panels, easier visibility and operator access

The PDF dimension section shows the different external dimensions and panel cutouts for DC1010, DC1020, DC1030 and DC1040, making panel fitment one of the first checks before replacement or new installation.

Product Sections

Honeywell DC1010 Digital Controller

The Honeywell DC1010 is the compact model in the DC 1000 Series. It is suitable when panel space is limited but the application still needs a practical industrial temperature controller.

Best for:
Small machine panels, compact heater control points, small ovens, dryers, packaging machines and OEM panels where 48 × 48 mm front size is preferred.

Why this model makes sense:
The DC1010 gives the buyer a compact 1/16 DIN controller format. This is useful when the machine panel has limited space or when an old compact controller needs replacement. It can still support core DC 1000 Series control functions depending on the ordered configuration, including PID/ON-OFF logic, output options, alarms and input selection.

Technical points to note:

Format: 1/16 DIN
Front size reference: 48 × 48 mm
PV/SP indication: 4-digit, 7-segment display
Input options: thermocouple, RTD or linear signal depending on model code
Input sampling time: 250 ms
Indication accuracy: ±0.2% FS
Control: PID or ON/OFF depending on setup
Power supply: AC 85–265 V, 50/60 Hz; optional DC24V configuration noted in PDF
Communication option: RS232 or RS485 depending on model selection

Where it is commonly used:

Small dryers
Packaging machines
Compact heater panels
Plastic processing auxiliaries
Small test rigs
OEM machine control panels

Selection caution:
Before selecting DC1010, confirm the exact panel cutout, input type, output type, alarm requirement and whether communication is required. Do not assume every DC1010 variant has the same output or communication configuration.

Honeywell DC1020 Digital Controller

The Honeywell DC1020 is a 1/8 DIN controller with a taller front layout. It is useful when the operator needs better visibility than a compact controller but the panel still requires a narrow vertical format.

Best for:
Machine panels, temperature control cabinets, packaging machines, dryers and process equipment where a 48 × 96 mm format is suitable.

Why this model makes sense:
The DC1020 format gives more front-panel display space compared to a compact square controller. This helps operators view PV, SP and status indicators more comfortably. It is especially useful when the controller is installed at eye level or in a vertical panel row.

Technical points to note:

Format: 1/8 DIN
Front size reference: 48 × 96 mm
Dual 4-digit displays for PV and SP
10 LED bargraph output indication
Up to 8 LEDs for output, alarm, auto/manual and programmer states

Industrial machine control panels

Selection caution:
For DC1020 replacement, check panel cutout and depth carefully. Also confirm whether the existing controller output is relay, voltage pulse, 4–20 mA, SCR/SSR or another output type.

Honeywell DC1030 Digital Controller

The Honeywell DC1030 is the 3/16 DIN model in the series. It is useful when a slightly larger square display is preferred for local operator readability and panel layout.

Best for:
Medium-sized panels, process control panels, climatic chambers, heating machines and applications where better operator visibility is needed.

Why this model makes sense:
The DC1030 gives a larger square format than DC1010, which can make it easier for operators and maintenance teams to read the display and access keys. It is useful in machines where the controller is not only installed for automatic control but also used for frequent setpoint changes or alarm checking.

Technical points to note:

Format: 3/16 DIN
Front size reference: 72 × 72 mm
Dual display for PV and SP
Bargraph output display
Supports setpoint programming depending on selected model
Supports multiple input types depending on configuration
Alarm modes: PDF mentions 17 alarm modes available
Programs: two programs with eight segments each are available in programmed versions

Where it is commonly used:

Climatic chambers
Medium-size dryer panels
Heat treatment support systems
Coating process panels
Packaging and sealing machines
Process temperature panels

Selection caution:
If the application requires ramp/soak or sequence-based temperature control, confirm the programmed version from the model code. The PDF model guide shows “C” for none and “P” for program selection, so this must be checked before purchase.

Honeywell DC1040 Digital Controller

The Honeywell DC1040 is the 1/4 DIN model and is the largest front-panel format in the DC 1000 Series. It is suitable where visibility, operator access and front-panel readability matter.

Best for:
Larger control panels, process heating systems, climatic chambers, coating lines, furnace-related panels and applications where operators frequently monitor or adjust the controller.

Why this model makes sense:
The DC1040 gives a 96 × 96 mm front size, making it easier to read from a distance compared to smaller controller formats. This helps in plant panels where operators need clear PV/SP visibility, alarm status and output indication. The PDF’s human-machine interface section shows the higher display for PV, lower display for SP, a 10 LED output bargraph and LEDs for OUT1, OUT2, AT, AL1, AL2, AL3, MAN and PRO states.

Technical points to note:

Format: 1/4 DIN
Front size reference: 96 × 96 mm
Dual 4-digit PV/SP display
10 green LED output bargraph
Auto/manual key operation
Alarm and program status indication
Suitable for applications needing frequent operator interaction
Supports multiple control and output configurations depending on model code

Where it is commonly used:

Climatic chambers
Painting and coating lines
Larger dryer panels
Plastic processing systems
Process heating panels
Industrial temperature control cabinets

Selection caution:
Do not select DC1040 only because it is larger. Confirm the panel cutout, output configuration, alarm count, communication requirement, program requirement and whether the controller must interface with PLC/SCADA.

Why the Honeywell DC 1000 Series Matters in Actual Plant Conditions

A controller affects both process quality and machine uptime. In a dryer, wrong tuning can create overheating or underheating. In a plastic process, unstable control can affect product quality. In a climatic chamber, poor control can affect testing accuracy. In packaging machinery, a weak temperature loop can affect sealing quality.

The DC 1000 Series supports control flexibility, including PID, ON/OFF, heat/cool logic, motor position control and phase-angle / zero-crossover control options. The PDF specifically explains phase-angle control and zero-crossover control for single-phase and three-phase loads, and notes that phase-angle control can support high-precision temperature control.

This matters because different heating systems need different control methods. A simple relay output may be enough for basic heater control, but SCR/SSR-based systems may need more specific output selection.

How the Honeywell DC 1000 Series Works

The controller receives an input signal from a temperature sensor or linear process signal. It compares the measured value with the setpoint and adjusts the output to control the process.

In practical terms:

The input tells the controller what the actual process value is.
The setpoint tells the controller what value the process should maintain.
The control algorithm decides how strongly the output should respond.
The output controls the final control element such as heater, SSR, relay, SCR or motor valve.
The alarm outputs alert the user when the process crosses configured limits.
The communication option allows integration with host systems through RS232 or RS485 Modbus RTU/ASCII.

The PDF also mentions that up to 30 DC1000 controllers can be connected to a single host computer, allowing the host to change setpoint, monitor PV/output or change configuration.

Key Selection Factors for Honeywell DC 1000 Series Controllers

1. Controller Size and Panel Cutout

First confirm whether the panel needs:

DC1010: 48 × 48 mm
DC1020: 48 × 96 mm
DC1030: 72 × 72 mm
DC1040: 96 × 96 mm

This is especially important for replacement jobs. A controller may have the right function but the wrong cutout.

2. Sensor Input Type

The PDF lists thermocouple inputs such as K, J, R, S, B, E, N, T, W, PL II, U and L, along with RTD options such as Pt100, JPt100 and JPt50. Linear input includes 4–20 mA.

Before buying, confirm whether your site uses thermocouple, RTD or linear signal.

3. Output Type

Output selection is critical. The model guide includes output options such as relay, voltage, 4–20 mA, single-phase SSR, three-phase SSR, motor valve, single-phase SCR, three-phase SCR and voltage outputs such as 0–5 V, 0–10 V, 1–5 V and 2–10 V.

Do not assume any DC1000 controller will directly replace another without checking output type.

4. Alarm Requirement

The PDF mentions up to three alarm outputs and 17 alarm modes depending on the configuration. Alarm functions can include deviation alarm, band alarm, high/low alarm, end-of-segment alarm, program run indication and timer alarm.

If the controller is used for safety interlocks, warnings or external annunciation, alarm count must be confirmed.

5. Communication Requirement

If the controller must communicate with a host system, confirm RS232 or RS485 requirement. The PDF mentions Modbus RTU/ASCII communication and baud rates from 2400 to 38400 bps.

For modern industrial panels, RS485 Modbus is commonly preferred when multiple controllers need to connect to a supervisory system.

6. Program Requirement

If the application needs ramp/soak or staged setpoint control, confirm the programmed version. The PDF states that two programs are available, with up to eight segments per program, and the two programs can be linked to form a 16-segment program.

7. Power Supply

The PDF states rated power supply of AC 85–265 V, 50/60 Hz, with optional DC24V. This helps in industrial panels because the same family can suit many AC supply environments, but the exact ordered power option must still be checked.

Common Applications of Honeywell DC 1000 Series

The Honeywell DC 1000 Series is suitable for:

Industrial dryers
Plastic processing machines
Packaging machinery
Painting and coating lines
Climatic chambers
Semiconductor packaging and testing
Heater control panels
Furnace auxiliary temperature control
OEM machine panels
Process temperature monitoring and control
SCR / SSR heater control systems
Multi-controller host communication systems

Common Mistakes to Avoid

Mistake	Why It Creates Problems
Selecting only by model family	DC1010, DC1020, DC1030 and DC1040 have different sizes and cutouts.
Ignoring input type	TC, RTD and linear input versions must match the field signal.
Assuming output type	Relay, SSR, SCR, 4–20 mA and voltage outputs are not interchangeable.
Not checking alarm count	Some applications need multiple alarms for safety and process indication.
Ignoring communication option	RS485/RS232 must be confirmed if PLC/SCADA/host connection is required.
Not confirming program option	Ramp/soak applications need programmed versions.
Ignoring power supply	AC and optional DC24V variants should be verified before ordering.
Buying only by front size	Control method and model code matter as much as physical size.

Do This, Not That

Do This	Not This
Select DC1010 / DC1020 / DC1030 / DC1040 based on panel cutout and visibility	Select only by product photo
Confirm thermocouple, RTD or linear input	Assume every controller accepts every sensor
Match output to heater, SSR, SCR, relay or motor valve requirement	Use any output and adjust wiring later
Confirm alarm count before purchase	Add external alarm logic after commissioning
Select RS485 if multiple controllers need host communication	Ignore communication until PLC integration stage
Check program requirement for ramp/soak applications	Buy non-program version for staged heating profile
Verify datasheet and model code	Order based only on old controller name

The PDF lists thermocouple inputs, RTD inputs such as Pt100 / JPt100 / JPt50 and linear input such as 4–20 mA depending on configuration.

6. Can the DC 1000 Series be used for ramp/soak programs?

Yes, programmed versions support two programs with eight segments each, and the two programs can be linked for a 16-segment program.

7. What should I check before replacing an old Honeywell DC controller?

Check panel cutout, supply voltage, input type, output type, alarm wiring, communication requirement and complete model code before replacement.

8. Is DC1040 always better than DC1010?

Not necessarily. DC1040 gives a larger 96 × 96 mm format, but DC1010 is better for compact panel space. The correct model depends on panel size, visibility and control requirement.
