The Omron CJ1W-MD231 PLC Digital I/O Unit combines 16 digital inputs and 16 NPN transistor outputs within one CJ-series Basic I/O module. The input section supports PNP/NPN signals at 20.4 to 26.4 V with an OFF/ON delay adjustable from 0 to 32 ms. Its output section operates from 10.2 to 26.4 V with a 0.5 A current rating, allowing Programmable Logic Controller logic to control compatible DC field devices. An FCN plug provides the I/O connection, while the CJ I/O Bus integrates the module into the controller architecture. The CJ1W-MD231 provides mixed digital I/O expansion and belongs to the PLC input and output range within Omron industrial controls.
