Omron CJ1W-ID211 Input Unit

The Omron CJ1W-ID211 Input Unit is a 16-point digital input module for Omron CJ1 PLC systems, designed to expand and reliably interface multiple sensor and switch signals within industrial automation panels. It accepts 24 VDC signals with sink or source input configuration depending on the model and uses photocoupler isolation to maintain noise immunity and signal integrity in challenging factory environments. The unit mounts on DIN rails or in a rack, terminates with screw terminals, and is built for straightforward expansion or replacement in packaging machines, conveyors, and automated production lines that rely on CJ1 series controllers. Operating from 0°C to 55°C with a standard input response, the CJ1W-ID211 carries the manufacturer part number CJ1W-ID211 / CJ1WID211 and is commonly replaced by CJ1W-ID261, CJ1W-ID232, or CJ1W-ID212 in compatible CJ1 installations.
