Comparing the CP1W-40EDT siblings
The CP1W-40EDT1 is a direct functional match — same 24-input/16-output solid-state architecture, same DIN-rail footprint and screw terminals — so it drops into the same slot without wiring changes. If you need relay outputs instead, the CP1W-40EDR swaps the solid-state outputs for 16 relays, changing the output technology but keeping the same form and wiring.
