Allen Bradley 1746-OV32 Digital Output Module

Product Introduction

The Allen-Bradley 1746-OV32 is a high-density digital output module designed for the SLC 500 programmable logic controller platform. It provides reliable and efficient control of DC-powered field devices in industrial automation systems where a large number of output points are required within limited panel space.

This module offers 32 transistor source output channels, supporting a 5–50 VDC output signal, making it suitable for a wide range of industrial loads such as solenoids, relays, indicators, and other DC actuators. The transistor sourcing design enables fast switching response and stable output performance, which is essential for high-speed and repetitive control applications.

The 1746-OV32 integrates seamlessly into SLC 500 I/O chassis, allowing system designers to expand output capacity without increasing cabinet footprint. Its proven design and compatibility make it a dependable choice for both new installations and upgrades of existing SLC 500 systems.
