Omron CJ1W-ID232 CJ Series 32‑Point DC Input Unit MIL Connector

Omron CJ1W-ID232 is a digital input unit for the SYSMAC CJ series modular PLC system. Provides 32 inputs for 24 V DC signals. PNP/NPN polarity‑configurable to adapt to both sourcing and sinking field devices. MIL connector interface enables high‑density, reliable wiring in control cabinets. The unit also features a configurable digital filter (0 … 32 ms) to reduce the influence of external noise. Designed for standard digital signal acquisition in medium to large automation applications.
