Allen-Bradley 1746-OX8 Output Module

The Allen-Bradley 1746-OX8 is an eight-point isolated relay output module for the SLC 500 family. It provides eight independently isolated relay contacts that can switch AC or DC loads within the voltage ranges of 5–250 V AC or 5–125 V DC, enabling versatile field wiring while protecting the 1746 backplane from transients and noise. This module plugs into a 1746 I/O backplane in an SLC 500 chassis, allowing direct control of relays, contactors, indicators, and other discrete loads in automation panels. Each contact is galvanically isolated from the backplane, supporting reliable operation in mixed-voltage environments and simplifying wiring by following standard Allen-Bradley I/O conventions for SLC 500 systems. Part of the 1746 discrete I/O lineup, the 1746-OX8 is designed for straightforward integration with existing AB controllers and backplanes, making it a practical choice for expanding or modernizing legacy automation setups that rely on relay switching for higher-current or higher-voltage loads.
