CJ1W-ID232 CJ Series 32-Point DC Input Module 24V MIL Connector | Omron

The Original New Omron CJ1W-ID232 is a 32-point DC input unit for the SYSMAC CJ series programmable logic controller (PLC) platform. It accepts 24 V DC signals from field devices such as sensors, pushbuttons, and limit switches, supporting both NPN and PNP output devices without the need for polarity selection. Featuring a MIL40 connector interface for high-density wiring and a configurable digital filter (0–32 ms) to reduce the influence of external noise, this module provides reliable digital signal acquisition for factory automation, machine control, and process automation applications. Part of the CJ-series Basic I/O Unit family, it is fully compatible with CJ1, CJ2, and NJ series CPU units.

Core Engineering Highlights:
32 digital inputs (24 V DC, NPN/PNP compatible) | 4.1 mA typical input current | 20.4–26.4 V DC permitted input voltage | 0–32 ms configurable OFF/ON delay | 1 MIL40 connector (plug not included) | 2 words allocated in I/O memory | 90 mA current consumption at 5 V DC | 20 × 90 × 83.6 mm (W × H × D) | 62 g weight | IP20 protection | 0°C to +55°C operating temperature
