About the Allen-Bradley 1746-OV32

The 1746-OV32 is an SLC 32 point digital output module, now discontinued. Its 32 outputs sit at 16 points per common in the 24V DC category, with an operating range of 5…50V DC, an on-state voltage drop of 1.2V at 0.5 A and a minimum load current of 1 mA. It draws 190 mA from the backplane.

What is the 1746-OV32 used for?

It switches 32 24V DC loads from an SLC 500 controller in one slot. Signal delays are 0.1 ms on and 1.0 ms off maximum, and surge current is 1.0 A per point at both 30 °C (86 °F) and 60 °C (140 °F).

Lifecycle and successor

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