Omron CJ1W-IC101 CJ Series I/O Control Unit for Expansion Racks

Omron CJ1W-IC101 is an I/O control unit for the SYSMAC CJ series PLC system. Mounted on the CPU rack immediately to the right of the CPU unit, it serves as the interface between the CPU rack and expansion racks. One I/O control unit is required when connecting one or more expansion racks to a CJ-series or NJ-series controller. Connects to the I/O interface unit (CJ1W-II101) on the expansion rack via an I/O connecting cable (CS1W-CN series).

Applications:

• Multi-rack configurations requiring additional I/O slots beyond the CPU rack

• Large-scale machine automation systems

• Material handling and conveyor control

• Packaging machinery and production line expansion
