Allen-Bradley 1746-OX8 Eight-Point Output Module

The Allen-Bradley 1746-OX8 is an eight-point isolated relay output module for the SLC 500 family, designed to drive external devices from a single 1746 I/O rack with galvanic isolation between channels. Each of the eight relay outputs is independently isolated, enabling eight loads to be controlled from the same module without cross‑talk, and it supports a broad load‑switching voltage range of 5 to 265 V AC or 5 to 125 V DC to accommodate diverse actuators, indicators, alarms, and control circuits. Intended for use in legacy AB SLC 500 installations, the 1746‑OX8 plugs into the 1746 backplane and interfaces with standard discrete I/O wiring, offering straightforward discrete on/off control for equipment such as solenoids, valves, relays, and signaling devices, all while preserving system reliability through the isolation the module provides.
