Multispan Industrial Timers and Counters: Types, Applications and Selection Guide

A packaging machine may need to wait three seconds before starting the next operation. A motor panel may need a timed star to delta changeover. A conveyor may need to count every product passing a sensor. A textile machine may need to measure how many metres of material have been processed.

All four applications involve automation, but they do not need the same instrument.

The first two are mainly time based operations. The last two are mainly count based operations.

This is the basic difference between industrial timers and counters.

Multispan's timer range on Radical TechMart includes universal programmable timers, ON/OFF delay timers, cyclic timers, forward reverse timers, star delta timers, power OFF delay timers, time totalisers and thumbwheel timers. The category also covers broader timer functions such as programmable, sequential, thumbwheel and real time clock based timing.

On the counting side, Radical TechMart lists Multispan batch counters and length counters for applications such as production counting, batch control and length measurement.

The right starting point is therefore not the model number.

Start by asking one question:

Does the machine need to act according to time, or according to a number of events?

What Is an Industrial Timer?

An industrial timer controls an operation according to a selected time interval.

A simple example is a motor that should start five seconds after a control signal is received.

The timer receives the trigger, measures the programmed time and changes its output when the timing condition is reached.

A typical sequence looks like:

Input Signal → Timer → Time Delay → Relay Output → Machine Action

Timers are commonly used where a machine needs a delay, repeated ON and OFF sequence, motor changeover, operating period or timed switching function.

Multispan's current range includes UTR universal timers as well as dedicated products for cyclic timing, forward reverse operation, ON/OFF delay, star delta timing and power OFF delay.

What Is an Industrial Counter?

A counter works with events rather than elapsed time.

Each time a sensor, encoder, micro switch or another compatible input generates a pulse, the counter records it.

For example:

Product Passes Sensor → Sensor Generates Pulse → Counter Adds 1

If 100 bottles pass the sensor, the counter can display 100.

Depending on the type of counter, it may also operate a relay when the programmed quantity is reached.

This makes counters useful for production quantity, batch counting, machine cycles, material length and other repetitive industrial processes.

Timer vs Counter: The Simple Difference

The confusion usually happens because both products may have a digital display, setting buttons and relay outputs.

Their purpose, however, is different.

Types of Multispan Industrial Timers

Universal Programmable Timers

A universal timer is useful when one panel or machine may require different timing functions.

Rather than designing a separate timer for every basic delay requirement, a programmable timer provides greater flexibility.

Radical TechMart currently lists Multispan UTR series products including UTR 413, UTR 433, UTR 1033, UTR 2033 and larger UTR 1244, UTR 2244 and UTR 4244 variants.

Best suited for: machine builders, OEM panels and automation applications where timing requirements may vary.

The main selection point is not simply the maximum time range. Confirm the timing mode, trigger method, number of outputs and required supply before selecting the model.

ON/OFF Delay Timer

An ON delay or OFF delay timer is useful when an output should change state after a defined delay.

For example:

A cooling fan may need to continue running after the main machine is switched OFF.

A conveyor may need to wait before another process starts.

Radical TechMart lists the Multispan DI 22 as an ON/OFF delay timer and the POD 30S as a power OFF delay timer.

Best suited for: machine sequencing, delayed switching and auxiliary control circuits.

Cyclic Timer

A cyclic timer repeatedly switches between ON and OFF periods.

Consider a lubrication pump that should run for a short period every few minutes.

Instead of continuously running the pump, the timer creates a repeating cycle:

ON → OFF → ON → OFF

Radical TechMart lists the Multispan CYL 22U specifically as a cyclic timer for industrial DIN rail applications.

Best suited for: repeated machine operations, lubrication cycles, intermittent equipment and repetitive control sequences.

Forward Reverse Timer

Some motor applications require alternating forward and reverse operation.

A timer can manage the changeover sequence so the motor operates in one direction for a selected period and then changes according to the required control logic.

The Multispan FRT 22U is listed as a forward reverse timer with dual relay outputs and a pause function.

Best suited for: equipment requiring repetitive directional operation.

The motor control circuit, interlocking and contactor arrangement must still be designed correctly. The timer is only one part of the control system.

Star Delta Timer

A star delta timer is designed for motor starting circuits where the motor initially runs through the star connection before changing to delta.

Radical TechMart lists the Multispan SDX 22 as a star delta timer with separate timed switching functionality for this purpose.

Best suited for: conventional star delta motor starter panels.

When selecting this timer, confirm the motor starter design and required transition timing instead of selecting only by supply voltage.

Time Totaliser

A time totaliser answers a different question:

How long has this equipment actually been operating?

The Multispan DTT Series is listed as a time totaliser or hour meter with a six digit display.

This can be useful for:

• Machine running hour monitoring
• Preventive maintenance planning
• Pump running time
• Generator or equipment operating hours
• Service interval tracking

A time totaliser does not necessarily control the machine. Its main job is to record accumulated operating time.

Types of Multispan Industrial Counters

Batch Counter

Suppose a packaging line needs 50 products in each batch.

A standard total count alone may not be enough. The machine needs to know when each batch reaches 50 while still keeping track of overall production.

This is where a batch counter becomes useful.

The Multispan BC Series listed by Radical TechMart includes separate total and batch displays, supports proximity sensor or micro switch inputs, and provides relay and buzzer outputs for batch operations.

A practical sequence may look like:

Sensor detects product → Counter increases → Preset quantity reached → Relay operates / buzzer alerts

Best suited for:

• Packaging lines
• Filling machines
• Conveyor batches
• Production quantity control
• Printing and labelling equipment
• OEM machine counting

The BC Series is specifically listed for packaging, filling, textile, printing, conveyor and production monitoring applications.

Length Counter

Not every production process is counted in pieces.

Textile, cable, film, paper and extrusion applications often need measurement in metres or another length unit.

A length counter receives pulses from a suitable sensor or encoder and converts them into a meaningful length measurement.

Radical TechMart lists the Multispan LC Series, including LC 1046D, LC 2046, LC 445 and LC 3006, for length and speed measurement using proximity or encoder inputs. The store specifically identifies textile, printing and extrusion as relevant applications.

Best suited for:

• Textile processing
• Cable measurement
• Printing machinery
• Film processing
• Extrusion lines
• Continuous material measurement

The important selection point is the relationship between mechanical movement and the pulse input. Incorrect pulse scaling can produce an incorrect displayed length even when the counter itself is working properly.

The Input Sensor Matters as Much as the Counter

A counter cannot count what it cannot detect.

Before selecting the counter, determine how the event will be sensed.

Depending on the application, this may involve:

• Proximity sensor
• Encoder
• Micro switch
• Machine generated pulse
• Other compatible switching input

The Multispan BC Series supports PNP/NPN proximity sensors or micro switches, while the LC Series is designed around proximity or encoder input for length measurement.

This is where many machine problems begin.

If the sensor misses products, produces multiple pulses for one product or is mounted incorrectly, changing the counter may not solve the problem.

Always inspect the complete sensing arrangement.

How to Choose Between a Timer and Counter

Start with the actual machine requirement.

Choose a timer when:

• The action depends on seconds, minutes or hours
• Equipment must start after a delay
• Equipment must remain ON for a fixed period
• An ON/OFF cycle needs to repeat
• A star delta changeover is required
• Forward and reverse operation requires timing
• Machine operating hours need to be recorded

Choose a counter when:

• Products need to be counted
• A batch must stop at a preset quantity
• Production output needs monitoring
• Machine cycles need to be counted
• Material length needs measurement
• Pulses from a sensor or encoder need to be totalised

In some machines, you may need both.

For example, a packaging machine may count ten products and then wait two seconds before starting the next batch.

The counter decides how many.

The timer decides how long.

Practical Example: Packaging Machine

Consider a machine packing bottles into groups of 12.

A proximity sensor detects every bottle entering the packing section.

The counter records each pulse.

When the count reaches 12, its output can signal the control circuit that the batch is complete.

The machine may then need a short delay before the next cycle starts.

That delay is the timer's job.

So the sequence becomes:

Sensor → Counter → Batch Complete → Timer Delay → Next Machine Cycle

Looking at the process this way makes component selection much easier than trying to start with product model numbers.

Practical Example: Motor Control Panel

Consider a motor that uses a star delta starter.

The motor starts in star configuration.

After the selected period, the timer changes the control sequence so the motor can transition to delta.

For this application, a dedicated star delta timer is more logical than a general production counter.

The Multispan range includes a dedicated SDX 22 star delta timer as well as forward reverse and cyclic timers for other motor control sequences.

Practical Example: Textile or Extrusion Line

Now consider a continuous roll of material.

Counting pieces is not useful because the product is continuous.

Instead, an encoder or suitable proximity arrangement provides pulses related to material movement.

A length counter converts those pulses into length.

Multispan's LC Series is designed for this type of measurement and is listed for textile, printing and extrusion applications.

• Input or trigger method
• Number of outputs
• Supply voltage
• Mounting requirement

For counters, tell us:

• What needs to be counted
• Sensor or encoder type
• Batch or total count requirement
• Expected counting speed
• Output requirement
• Panel size

This information makes it much easier to narrow down the correct product before comparing individual Multispan models.

Final Thoughts

Timers and counters may look like simple panel instruments, but they solve two fundamentally different automation problems.

A timer answers:

When should something happen?

A counter answers:

How many times has something happened?

Once that difference is clear, product selection becomes much easier.

For a delay, cyclic operation, motor sequence or running hour requirement, begin with the timer function.

For production quantities, batches or material length, begin with the counter and the sensor generating the pulses.

In industrial automation, the correct timer or counter is selected by understanding the machine sequence first and the model number second.
