OMRON CS1W-ID231 32-Point DC Input Module for CS1 Series PLCs

The OMRON CS1W-ID231 (CS1W-ID231) is a high-density 32-point DC input module designed for use with OMRON CS1 series programmable logic controllers. Engineered for robust discrete signal acquisition, this digital input module operates at a rated input voltage of 24 V DC with an input current of 6 mA per point. It interfaces directly with field devices such as sensors, limit switches, and pushbuttons, converting external input signals into logic states for the central processing unit across two allocated data words. The module draws 0.15 A at an internal supply voltage of 5 V DC from the backplane, ensuring energy-efficient operation within the rack assembly. Built to maintain high operational reliability in demanding factory environments, the CS1W-ID231 is widely deployed in automated manufacturing lines, material handling systems, packaging machinery, and general industrial machine control. It provides fast response times and dependable isolation to protect core controller electronics from external electrical disturbances during continuous operation.
