Allen-Bradley 1746-OV16 SLC 500 DC Output Module

The Allen-Bradley 1746-OV16 is a 16-channel current sinking DC output module for the SLC 500 family, designed to drive DC loads from a 10 to 50 V DC supply with a nominal 24 V DC rating. It occupies a standard open-style SLC 500 backplane and provides sixteen DC sink outputs that complete the circuit by pulling loads to the common return. As part of the 1746 I/O family, the OV16 is intended for digital control within industrial automation, coordinating with SLC 500 processors and other 1746-series modules to implement concise control logic. Typical load types include solenoids, relays, indicators, and other 24 V DC devices, making it suitable for straightforward actuation and sequencing tasks in conveyors, robotics, and packaging lines. Key specs shown in product listings and installation guides include 16 outputs, a 10–50 V DC operating range, and a nominal 24 V DC signal, with the 1746-OV16 noted as a current sinking module within the SLC 500 ecosystem.
