The Omron CJ1W-OC201 PLC Relay Output Unit provides 8 normally open relay outputs for switching external electrical loads from a CJ-series Programmable Logic Controller system. Each output supports up to 2 A across a permitted output voltage range of 5 to 250 V, allowing PLC control logic to interface with compatible field loads requiring relay switching. Screw-terminal connections provide the wiring interface for installation inside industrial control panels. As a Basic I/O Unit, the module operates through the CJ I/O Bus and integrates with other CJ-series control modules in the PLC architecture. The CJ1W-OC201 extends CJ1W relay output capacity and forms part of the relay output PLC range used in Omron machine automation.
