Allen Bradley 1771-OBN DC High True Output Module

Product Introduction

The Allen-Bradley 1771-OBN DC High True Output Module is a high-performance digital DC output module for the PLC-5 1771 I/O platform by Allen-Bradley. It provides precise DC output control to operate industrial field devices, translating PLC digital signals into reliable high-true DC outputs.

This module features multiple DC output channels with a high-true logic configuration, making it suitable for controlling solenoids, relays, and other DC-powered devices. Each output can handle up to 0.5 A continuously, with a total module current rating of 8 A. The module operates within a 10–30 VDC range and can source voltages up to 60 VDC, drawing 330 mA from the 5 VDC backplane.

Installed in a standard 1771 I/O chassis, the 1771-OBN integrates seamlessly with PLC-5 systems for industrial automation applications that require accurate and dependable DC output control.
