About the Allen-Bradley 1746-OX8
The 1746-OX8 is an SLC 8 point relay output module, now discontinued. Each of its 8 AC/DC relay outputs is individually isolated, working from 5…125V DC and 5…265V AC (selection guide 1747-SG001). It draws 85 mA at 5V and 90 mA at 24V from the backplane.
What is the 1746-OX8 used for?
It switches loads on separate circuits from an SLC 500 controller, since every point is isolated. Minimum load current is 10 mA at 5V DC and off-state leakage is 0 mA. The signal on delay is 10 ms maximum with a resistive load, and current per point follows the relay contact ratings.
Lifecycle and successor
Discontinued (Rockwell Automation lifecycle status, checked 24 October 2026).
Before you order
What to photograph or confirm so the right unit is quoted.
