Allen-Bradley 1746-OV32 32-Point DC Output Module

Allen-Bradley 1746-OV32 is a 32-point digital DC output module for SLC 500 controllers, providing sinking (low-side) transistor outputs for 5 to 50 V DC field loads with a nominal operating voltage around 24 V DC. The module supports two isolated output groups, each with its own VDC and return pins, which simplifies wiring and maintains electrical separation between load sets. It plugs into the 1746 I/O backplane in SLC racks and is commonly used to drive relays, contactors, indicators, and other DC devices controlled by PLC logic. With 32 outputs available in a compact 1746-form factor, the OV32 enables high-density control of DC loads, and is designed to integrate with related 1746 I/O modules and a separate DC power source for the field side.
