A. Product Overview
The Autonics TCN4S-24R Temperature Controller belongs to the TCN series of economical dual display PID temperature controllers. It is designed for applications where process temperature must be continuously measured, displayed and maintained at a preset value.
The controller uses separate displays for the Process Value, PV, and Set Value, SV, allowing operators to view the actual temperature and desired temperature simultaneously.

B. Working Principle
The Autonics TCN4S-24R PID Temperature Controller works by continuously receiving a temperature signal from a connected thermocouple or RTD sensor.
For example, if the required temperature is 150°C, the operator sets the Set Value to 150°C.
The temperature sensor measures the actual process temperature and sends it to the controller. The controller displays this measurement as the Process Value.
The TCN4S-24R then compares:
Actual Temperature, PV
with
Required Temperature, SV
If there is a difference between these values, the controller operates its relay or SSR drive output to control the connected heater or other temperature control equipment.
With PID control, the controller continuously calculates the difference between the Process Value and Set Value and adjusts the control output accordingly.
This helps to:
Reduce temperature overshoot
Improve temperature stability
Reach the set temperature efficiently
Maintain consistent process temperature
Reduce repeated switching compared with basic ON and OFF control
The 100 ms sampling cycle allows the controller to monitor temperature changes rapidly and respond to process variations.
C. Why Is Autonics TCN4S-24R Used?
The Autonics TCN4S-24R is used when an industrial process requires automatic and accurate temperature control.
Instead of manually switching heaters ON and OFF, the controller continuously monitors the sensor and automatically operates the control output.
Common Applications
The TCN4S-24R can be used in:
Industrial ovens
Heating machines
Industrial furnaces
Packaging machines
Plastic processing machinery
Sealing machines
Food processing equipment
Dryers
Heating chambers
Temperature controlled tanks
Industrial heaters
Laboratory equipment
Control panels
OEM machinery
Process automation systems
It is particularly useful where the machine already uses a thermocouple or Pt100 RTD sensor and requires a compact panel mounted temperature controller.
