Description

The Allen-Bradley 1746-OB32 is a high-density digital output module designed for the SLC 500 programmable logic controller (PLC) platform. This module provides 32 points of transistor source output, making it an efficient solution for controlling a wide range of DC-operated industrial devices such as solenoids, contactors, and indicators. Engineered for reliability in demanding automation environments, the 1746-OB32 integrates seamlessly into the SLC 500 chassis, offering robust performance for complex control applications.

Features

32-point transistor source output configuration.
Wide operating voltage range of 5-50 VDC.
Two groups of 16 outputs per common for flexible wiring.
Low backplane power consumption of 190 mA at 5 VDC.
Compact open-style enclosure for standard SLC 500 rack mounting.

Applications

This module is widely utilized in manufacturing and process control systems where high-density DC output switching is required. Typical applications include machine tool control, assembly line automation, packaging equipment, and material handling systems that rely on the SLC 500 architecture.
