It terminates signals via screw terminals, which simplifies field wiring compared to D-Sub or rectangular connectors used on other CJ1W I/O siblings. Rated for CE and cULus, it installs directly on the backplane bus of a CJ-series CPU rack or expansion rack. ## How it compares to similar CJ1W modules The closest peer in function is the CJ1W-MD261, which also offers 32 inputs and 32 outputs but terminates through a D-Sub connector rather than screw terminals. If your panel is wired with pre-made D-Sub cables, the MD261 saves termination time; if you prefer field-terminated screw clamps, the B7A22 is the direct choice. Another sibling, the CJ1W-MD563, uses a rectangular connector which is less common in field retrofit but standard for factory harnesses. The CJ1W-B7A14 is input-only (64 inputs, no outputs) and is not a functional replacement. Mounts to DIN rail and occupies one slot in a CJ-series rack. The screw terminals accept conductors; no special backplane power calculation required—the module draws its logic power from the rack bus.","metaTitle":"CJ1W-B7A22 I/O Module, 32 In 32 Out, Screw Terminals","metaDescription":"CJ1W-B7A22 I/O module for Omron CJ series. 32 digital inputs and 32 outputs with screw terminals, DIN rail mount, CE/cULus approved.

Neither is a direct drop-in due to different termination styles, but either can replace the B7A22 if the wiring harness matches."},{"question":"What is the listed type of the CJ1W-B7A22?","answer":"It is classified as an Input, Output (I/O) Module."},{"question":"What series does the CJ1W-B7A22 belong to?","answer":"It is part of the CJ1W series for the Omron CJ platform."},{"question":"Will the CJ1W-B7A22 drop into a panel specified for the CJ1W-B7A14 without rewiring?","answer":"No. The CJ1W-B7A14 provides 64 inputs and no outputs, so it cannot handle the output signals the B7A22 supports.
