CJ1W-TC102 integration brief
The CJ1W-TC102 is a four-channel RTD input module for the Omron CJ-series PLC rack. Four solid-state outputs can drive heaters, solenoid valves, or alarms directly for loads within the rated current. DIN-rail mounted with screw terminals. Features RTD input only — no thermocouple support.
Sourcing reality
When sourcing a second unit for a BOM that originally specified CJ1W-TC101, the CJ1W-TC102 is a drop-in functional equivalent: same DIN-rail footprint, same 4 analog input / 4 solid-state output architecture, same screw terminals and RTD support. No rewiring needed at the backplane or field terminations.
Compliance and documentation pack
The module carries CE, cULus, Lloyd, and NK approvals. Nameplate mark matches the order code CJ1W-TC102 exactly with no region-specific suffix.
