Omron CJ1W-B7A14 packs 64 digital inputs into a single DIN-rail slice – that's 64 prox, limit, or pushbutton signals on one slot, freeing backplane capacity for output or specialty modules. Screw terminals keep field wiring fast; no spring clamp learning curve.
How it sits against the CJ1W-B7A22
The CJ1W-B7A14 is a pure input module: 64 points, no outputs. Its sibling CJ1W-B7A22 splits 32 inputs and 32 outputs on the same footprint. If your BOM calls for high-density input monitoring and you don't need local outputs, the B7A14 keeps I/O count tighter. Swapping one for the other means re‑assigning I/O tables and checking wiring – not a drop‑in swap.
Installation notes
DIN-rail mount with screw-clamp terminals; connects to CJ-series CPU via the backplane without separate power wiring. 64 inputs map to consecutive I/O words—verify slot assignment in CX-Programmer.
