About the Allen-Bradley 1746-OW16

The 1746-OW16 is an SLC 16 point relay output module, now discontinued. Its 16 AC/DC relay outputs sit at 8 points per common, working from 5…125V DC or 5…265V AC, with a minimum load current of 10 mA at 5V DC. It draws 170 mA at 5V and 180 mA at 24V from the backplane.

What is the 1746-OW16 used for?

It switches AC or DC loads from an SLC 500 controller through relay contacts. The signal on delay is 10 ms maximum with a resistive load and off-state leakage is 0 mA. Current per point follows the relay contact ratings; per module it is 16.0 A AC, 8.0 A per common.

Lifecycle and successor

Discontinued (Rockwell Automation lifecycle status, checked 24 October 2026).
