Omron CJ1W-ID262 CJ Series 64‑Point DC Input Unit MIL Connector

Omron CJ1W‑ID262 is a 64‑point digital input unit for the SYSMAC CJ series. It accepts 24 V DC signals from field devices and transfers them to the CPU. Both PNP and NPN polarity can be mixed without hardware changes. The unit mounts on a DIN rail and uses two MIL40 connectors (40‑pin, 2‑way) for high‑density wiring.

Applications:

• High‑density digital input expansion for CJ‑series PLC systems

• Large‑scale machine automation and control panels

• Material handling systems, conveyors, and packaging equipment

• Production line monitoring and process data acquisition

• Retrofit of existing CJ1 systems requiring additional input points

Advanced Specifications:

• Digital filter: programmable 0‑32 ms (reduces external noise influence)

• Polarity compatibility: supports both NPN and PNP output devices without selection

• Insulation resistance: 20 MΩ min. between external terminals and GR terminal (100 V DC)

• Dielectric strength: 1,000 V AC between external terminals and GR terminal for 1 min (leakage current ≤ 10 mA)

• Word allocation: 4 words (64 points)

• Connection notes: wire both COM pins for each connector (A9/A18 for CN1, B9/B18 for CN1; both COM2/COM3 pins for CN2)

• Input power polarity: can be connected in either direction

System Integration:

• This input unit belongs to the Omron SYSMAC CJ series.

• Installs on CPU Rack or Expansion Rack via CJ I/O Bus.

• Compatible with CJ1, CJ2, and NJ series CPU units.

• Configured in CX‑Programmer via I/O Table and Unit Setup.

• Requires MIL40 connector cables (e.g., XW2Z-0030FF-L) or terminal conversion units (e.g., XW2D-40G6, XW2K-40G-O32C) for field wiring – connectors are not included with the unit.
