The Omron CJ1W-TC102 PLC Temperature Control Unit provides 4-point thermocouple control within a CJ-series Programmable Logic Controller system. It supports K, J, T, E, L, U, N, R, S, and B thermocouple types, allowing different temperature measurement requirements to be incorporated into the controller architecture. PID and ON/OFF control methods provide alternative approaches for regulating temperature according to the process, while a 500 ms sampling period supports ongoing measurement and control. Its four-point configuration enables several temperature control points to operate through one CJ1W module alongside other machine functions. The CJ1W-TC102 extends CJ1W thermal control capability and belongs to the multi-point PLC temperature control range within Omron process automation.
