The Omron CJ1W-TC003 PLC Temperature Control Unit provides 2-point control using Pt100 and JPt100 platinum resistance thermometer inputs within a CJ-series Programmable Logic Controller system. PID and ON/OFF control methods provide alternative approaches for regulating temperature according to the process, while a 250 ms sampling period supports ongoing measurement and control. Integrating the temperature inputs into the PLC architecture allows thermal process information and machine-control logic to operate within the same automation system. Its two-point configuration suits applications requiring a compact number of controlled temperature zones. The CJ1W-TC003 extends CJ1W temperature regulation capability and forms part of the PLC temperature control range available for Omron process automation.
