This Omron CP1WCIF41.1 is an Ethernet communications board that plugs into a CP1L-M or CP1L-L14/L20 CPU. It gives that PLC a standard RJ45 Ethernet port—no special cables, no adapter bricks. The board is listed as current-production, so you're buying a factory-supported part, not a faded surplus item.
Fits CP1L-M and CP1L-L14/L20 CPUs. RJ45 termination for Ethernet communication.
