Omron CJ1W-TC101 Temperature Controller

The Omron CJ1W-TC101 is a compact, high-performance temperature control unit designed for the CJ-series PLC platform. This special I/O module provides 4 independent temperature control loops, accepts thermocouple inputs (types R, S, K, J, T, B, L), and features open-collector NPN pulse outputs for SSR drive. It’s ideally suited for multizone heating and cooling applications requiring precise, fast-response control.

Designed to fit into tight spaces and integrate seamlessly with CJ-series CPUs, the CJ1W-TC001 provides a reliable solution for embedded thermal control in manufacturing, packaging, and process automation.
