Product details

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. Orders are quoted to your BOM quantity with the standard factory lead time; no surplus-channel contingency needed.

Frequently asked questions

What is the closest functional substitute — CJ1W-MD232?

CJ1W-MD232 has the same I/O count and connector type, but adds Lloyd's Register approval. It is a drop-in replacement for panels that do not require Lloyd certification.

What is the listed type and series of CJ1W-MD233?

Type: Input, Output (I/O) Module. Series: CJ1W.

Will CJ1W-MD233 drop into a panel wired for CJ1W-MD232?

Yes, both use the same rectangular connector and DIN-rail mounting. No rewiring needed if panel approvals allow the MD233's approval set (CE, cULus, NK) instead of MD232's (which adds Lloyd).

What compliance documentation is available for CJ1W-MD233?

The module carries CE, cULus, and NK approvals. Those certifications are documented per the manufacturer's declaration.
