The Omron CJ1W-OC211 PLC Relay Output Unit provides 16 normally open relay outputs for switching external electrical loads from a Programmable Logic Controller system. Each output supports switching up to 2 A, allowing the module to interface PLC control logic with relays, indicators, solenoids, and other field loads. Screw-terminal connections provide a practical wiring interface for installation inside industrial control panels. As a Basic I/O Unit, the module communicates through the CJ I/O Bus and works alongside CPU, input, and communication modules within the controller configuration. The CJ1W-OC211 belongs to the CJ1W Series and expands the PLC output control range available for Omron machine control applications.
