The Omron CJ1W-OD203 PLC Digital Output Unit provides 8 NPN transistor outputs for controlling compatible DC field devices from a CJ-series Programmable Logic Controller system. Its outputs operate within a permitted voltage range of 10.2 to 26.4 V with a rated output current of 0.5 A, providing electronic switching capacity for machine-control applications. Screw terminals provide the field wiring interface, while the module communicates through the CJ I/O Bus as a Basic I/O Unit. Its eight-point configuration suits systems requiring a compact number of additional NPN transistor-controlled outputs. The CJ1W-OD203 extends CJ1W digital output capability and belongs to the 8-point NPN PLC output range supporting Omron machine automation.
