Field note – CJ1W-ID201
The Omron CJ1W-ID201 is the 8-point DC input module for the CJ Series rack – 12 to 24 VDC on screw terminals, DIN rail mounted, approval-stamped for CE, cULus, Lloyd, and NK. Straightforward part: wire the field sensors to the screw clamp, slot it into the backplane, and map the inputs in the CX-Programmer I/O table.
Not a swap for CP1W-32ET
The CP1W-32ET that sometimes floats up in cross-references is an output module – 32 solid-state outputs, not inputs. Different direction, different wiring, and unrelated point count. The CJ1W-ID201 stays in the input slot; don't let the CP1W prefix trick you into a misorder.
