What it is and what ships in the carton
CJ1W-CIF21 is a Communications Module in the Omron CJ1W series, running on 24VDC and mounting on DIN Rail. It combines a D-Sub connector and screw terminals for field wiring and is compatible with CJ, CP2MA, CQM1A, and CS Series CPUs. What ships in the carton? Just the module in a bulk pack—no cables, connectors, or mounting hardware. Verify your accessory list before the tech heads to the panel.
Lifecycle and sourcing reality
This module is officially obsolete. There is no direct Omron replacement announced. For a line-down or BOM freeze, we can source CJ1W-CIF21 through our surplus and broker network. Submit an RFQ to confirm lead time and condition. If you need a current-production alternative, evaluate the CJ1W-CORT-21 communications module—but check the termination difference noted below.
