The Omron CJ1WOD231CHN is a 32-point transistor output module for the CJ-series PLCs, delivering 500 mA per output at 24 VDC from a slim 20 mm DIN-rail footprint. It sits as a straight 32DO block – no isolation per group, so plan your load grouping accordingly.
Width of 20 mm matters when you're filling a CJ rack – it's one of the slimmer output modules, so it leaves room for additional slices. Depth of 83.6 mm clears most standard cabinets, but check against your gland plate or door clearance if you're packing the rail tight. Operating temperature from 0 to 55 °C, so it's fine for an unventilated panel as long as you're not stacking high-heat gear right next to it.
