The Omron CS1W-B7A22 is a backplane-mount interface module for the CS Series, equipped with 32 digital inputs and 32 solid state outputs fed from a 12-24VDC supply. Screw terminals land field wiring; the module draws its power and communicates over the CS backplane, so no separate control power wiring is needed.

Frequently asked questions
What is the CS1W-B7A22's type and series?
It is an Interface Module in the CS1W series, designed for Omron CS Series programmable controllers.
Will the CS1W-B7A22 drop into a panel built around a CP2E I/O module?
No – the mounting method is different. The CS1W-B7A22 mounts on a backplane (rack) while the CP2E modules are DIN-rail mounted. The backplane card will not physically fit in a CP2E panel without replacing the entire rack.
What compliance documentation does Omron provide for the CS1W-B7A22?
The module is approved under CE and cULus. These certifications cover the essential safety and EMC requirements for industrial control equipment in most regions. For specific declarations or certificates, include the request with your RFQ.
