What it is and where it lands
The Omron CP1W-ADB21 is a 2-channel analog input option card for the CP1W series. It mounts inside the CP1L-E or CP1W base unit, adding two analog inputs to the controller without consuming additional I/O slots. Rated for current production, it's a straightforward line-fill for a BOM that needs analog sensing but no analog output.
