The Omron CJ1W-OD231 PLC Digital Output Unit provides 32 NPN transistor outputs for switching compatible DC field devices from a CJ-series Programmable Logic Controller system. Each output supports a rated current of 0.5 A within a permitted output voltage range of 10.2 to 26.4 V, providing a high-density output configuration for industrial control applications. An FCN plug connection is used for I/O wiring, with the plug supplied separately, while communication through the CJ I/O Bus integrates the module as a Basic I/O Unit. Its 32-point design supports systems requiring multiple output commands from one module. The CJ1W-OD231 expands CJ1W digital output capacity and belongs to the NPN transistor PLC output range within Omron control systems.
