Product details

The Omron CJ1W-MD232 is a mixed I/O module for the CJ Series PLC backplane, combining 16 digital inputs and 16 solid-state outputs in a single slot. It uses a rectangular MIL connector for pre-wired cable assemblies and mounts on DIN rail. This form factor saves rack space and reduces wiring compared to separate input and output modules, making it suitable for machine control applications with balanced discrete signal counts.

The CJ1W-MD232 is functionally nearly identical to the CJ1W-MD233: same 16 digital inputs, 16 solid-state outputs, rectangular connector, and DIN rail mounting. The only documented difference is approval scope — the MD232 carries Lloyd's Register marine certification (plus NK), while the MD233 does not. If Lloyd approval is not required, the MD233 is a direct drop-in alternative; for marine or offshore installations, the MD232 is the specified choice. A third sibling, CJ1W-MD231, uses a D-Sub connector instead of rectangular — verify your cable harness before substituting.

Sourcing and integration

The CJ1W-MD232 mounts on DIN rail and uses a rectangular connector for CJ Series backplane integration. It carries CE, cULus, Lloyd, and NK approvals.

Frequently asked questions

What type of module is the CJ1W-MD232?

It is an Input/Output (I/O) Module with 16 digital inputs and 16 solid-state outputs.

Will the CJ1W-MD232 drop into a panel originally specified with the CJ1W-MD233?

Yes, provided the cabling uses a rectangular (MIL) connector. Both modules share the same dimensions, mounting, and connector type, so no rewiring is needed if the existing harness is rectangular. If the panel was wired for a D-Sub connector (CJ1W-MD231), the rectangular connector on the MD232/MD233 will not mate without an adapter or new cable.

What compliance documentation does the CJ1W-MD232 carry?

The module is approved under CE, cULus, Lloyd's Register, and NK (Nippon Kaiji Kyokai). These cover industrial safety and marine classification requirements. RoHS/REACH declarations are not separately listed but are implied by CE marking for the EU market.
