Allen-Bradley 1746-OX8 SLC 500 8-Point Output Module

The Allen-Bradley 1746-OX8 is an eight-point isolated relay output module for the SLC 500 family, delivering eight independent relay contacts that can switch industrial loads across a wide voltage range, up to 265 VAC or 125 VDC, enabling safe, isolated control of multiple devices from a single controller. Each output is individually isolated from the others to prevent electrical interference, and the module is designed in an open-style chassis that mounts in standard SLC 500 backplanes for straightforward installation and replacement. The eight contacts are normally open (NO) contacts, with the documented operating voltage spans 5-265 VAC or 5-125 VDC per channel, allowing flexible wiring schemes for AC or DC loads. As part of the SLC 500 I/O ecosystem, the 1746-OX8 mates with compatible 1746-series racks and backplanes and complements other digital I/O modules in a single enclosure, making it suitable for expanding relay-based control within legacy automation systems.
