Part Identity and Fit
The CS1WCN223CHN is a 2-meter connecting cable with D-Sub connectors, specified by Omron for CS1 Expansion I/O Backplanes. It's the exact cable you'd find between a CS1 CPU rack and an expansion I/O rack in a CS1-series PLC system. The D-Sub termination on both ends mates directly with the backplane connectors; no adapters needed. Length is 2 m — enough for a standard cabinet layout without excess slack.
