Product Overview

The 1738-OW4M12 from Allen-Bradley is a rugged 4-channel relay output module designed for on-machine applications. It belongs to the ArmorPoint I/O family, providing reliable control for actuators, solenoids, and other industrial devices.

With Form A (normally open) isolated relays, this module ensures flexible and safe output operation. Its M12 connectors allow fast, secure wiring and support quick replacement. The IP69K-rated housing withstands high-pressure washdowns, making it ideal for food, beverage, and pharmaceutical environments.

This module supports RIUP (Removal and Insertion Under Power) and Auto Device Replacement (ADR), which minimizes downtime and simplifies maintenance. Integrated LED indicators display module, network, and output status, enabling efficient diagnostics.
