Temperature Controller
E5C2
DIN-sized (48 x 48 mm) Temperature
Controller with analogue setting
• Compact, price effective Temperature Controller.
• Incorporates proportional control and reset adjustment function.
• Consecutive mounting possible using mounting adapter.
• Incorporates a plug-in socket, allowing DIN-track and flush
mounting.
Refer to Safety Precautions for All Temperature
Controllers.

safety standards, refer to your OMRON website.
Model Number Structure
■ Model Number Legend
1. Control Outputs
R: Relay
2. Control Method
20: ON-OFF control
40: Proportional control
3. Input
K: K-type thermocouple
J: J-type thermocouple
P-D: Platinum resistance thermometer (Pt100)
G: Thermistor with replaceable element
4. Power supply voltage:
AC100-240: 100 to 240 VAC
5. Temperature range
E.g. “0-200”: 0 to 200 °C
Note: A functional explanation is shown in the below table: But
models are not necessarily available for all possible
combinations. Refer to Ordering Information when ordering.
Examples
• Relay control output, ON/OFF control, K-type thermocouple
input, 100 to 240 VAC power supply voltage, 0 to 200 °C:
E5C2-R20K AC100-240 0-200
• Relay control output, proportional control, Relay control
output, K-type thermocouple, 100 to 240 VAC power supply
voltage, 0 to 800°C:
E5C2-R40K AC100-240 0-800
