Discrete Output Module Allen-Bradley 1746-OB32 SLC 500 32 Outputs

Product Overview

The Allen-Bradley 1746-OB32 is a digital DC output module from the SLC 500 series. It provides thirty-two outputs for high-current applications. This module operates on a 5-50 Volts DC range. Each output can handle 0.5 to 0.25 amps. The total module current is 8 amps. It uses a 190 milliamps backplane current at 5 Volts. The nominal output voltage is 24VDC. This module is ideal for controlling solenoids, motor starters, and other industrial loads. It offers a step response of 60 milliseconds in and 2.5 milliseconds out. Signal delays are 0.1 ms for ON and 1.0 ms for OFF. The module has sixteen points per common. It does not include electronic protection. This product is built for reliable performance in harsh factory environments.

Application Scenarios

This output module works well in many automation tasks. Use it in assembly lines for actuator control. It can manage conveyor systems with ease. The 1746-OB32 is suitable for packaging machines. It also fits into material handling equipment. Its high current capacity supports larger loads. The module works with PLC systems from Allen-Bradley. It is a good choice for retrofitting older SLC 500 racks. Factory engineers use it for discrete output switching. The module handles both low and medium voltage DC loads. It is a cost-effective solution for batch processes.
