The Omron CS1W-ID261 is a high-density DC Input Unit designed for the CS1 series of Programmable Logic Controllers (PLCs). It provides 64 input points in a single slot, making it an excellent solution for applications requiring a large number of discrete inputs while conserving space in the control panel. This module is engineered for reliability, featuring photocoupler isolation to protect the PLC’s internal circuitry from field-level electrical noise and transients. It utilizes two 40-pin Fujitsu-compatible connectors for streamlined and secure wiring, ideal for interfacing with sensors, push buttons, and other 24 VDC field devices in industrial automation systems.
