Omron CJ1W-MD233 is a CJ Series I/O module with 16 digital inputs and 16 solid-state outputs. The rectangular connector mates with standard CJ I/O wiring units; the DIN-rail mount aligns with the rack. Approvals cover CE, cULus, and NK.
The closest functional sibling is CJ1W-MD232 — same 16-input/16-output layout, same rectangular connector, same DIN-rail footprint. The one difference a procurement engineer should flag: MD232 adds Lloyd's Register approval (alongside the CE, cULus, NK that both carry). If your panel specification requires Lloyd certification, source the MD232; if not, MD233 is an identical fit for wiring and I/O mapping.
Lifecycle status is Active. No end-of-life notice or last-time-buy window — this module is a current-production line item. Orders are quoted to your BOM quantity with the standard factory lead time; no surplus-channel contingency needed.
