What this module is and what it fits
The CRT1B-MD04SLP is an Input, Output (I/O) Module with 2 digital inputs and 2 solid-state outputs, designed for use with Omron CJ, CS, and NJ series PLCs. Rated IP54 — dust protected and water resistant — so it suits panels where splash or dust ingress is a concern, unlike the IP20-rated CRT1B-MD04JS sibling. Termination is via spring terminal and wire lead; the module chassis-mounts and operates from -10°C to 55°C.
Lifecycle and sourcing reality
This part is discontinued per Omron's product status. There is no official successor order code listed; sourcing will be through surplus or broker channels. Submit an RFQ for current availability and lead time.
Integration notes
Spring terminal and wire lead termination. IP54 seal allows mounting in washdown zones without an additional enclosure. Compatible with CJ, CS, and NJ series backplanes; no special adapter required. The solid-state outputs are rated for the same load type as the sibling modules in the CRT1B family.
