The Omron CJ1W-ID231 Digital Input Module is a digital input expansion module for Omron CJ1W PLC systems, enabling the controller to read external on/off signals from field devices. It translates sensor and switch states into digital inputs that the CJ1W controller can process for control and monitoring within a modular automation setup. As part of the CJ1W family, the ID231 extends input capability for applications requiring multiple binary inputs in industrial automation projects.
