Allen-Bradley 1746-OX8 Isolated Relay Output Module

The Allen-Bradley 1746-OX8 is an eight-channel isolated relay output module for the SLC 500 PLC family, providing eight individually isolated relay outputs on a single 1746 backplane card. It supports a load voltage range of 5-265 VAC or 5-125 VDC, with a maximum current per output of 3 A at 120 VAC or 1.2 A at 24 VDC. Backplane current draw is 85-90 mA, and the module features channel-to-channel isolation with a step response of 60 ms in and 2.5 ms out, enabling reliable switching of loads in discrete-control applications. Common uses include energizing solenoids, contactors, lights, and other discrete devices within the specified voltage and current limits in SLC 500 installations.
