Product details

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.

Status is active per manufacturer. No last-time-buy or end-of-life narrative here. We quote the ADB21 to order against an RFQ; bulk packaging means it arrives loose, not boxed. For a BOM freeze, this line item requires no accelerated buy or special handling.

Frequently asked questions

What is the closest functional second-source — CP1W-MAB221?

The CP1W-MAB221 is a peer card that adds two analog outputs alongside the two inputs. If your design needs outputs, it is the functional alternative; if not, the ADB21 covers the input side at lower cost.

What series is CP1W-ADB21 in?

CP1W series.

What package is it?

Bulk.

Will CP1W-ADB21 drop into a panel specified around CP1W-MAB221 without rewiring?

Mechanically and electrically the same footprint and connector. If the panel's wiring only uses the input pins, you can swap without rewiring. If analog outputs are used in the design, the ADB21 lacks the circuits to drive them, so a replacement would require rewiring the output channels.
