Allen Bradley 1746-OB16E Digital DC Output Module

Product Introduction

The Allen-Bradley 1746-OB16E is a DC digital output module designed for the SLC 500 programmable controller platform. It provides 16 electronically protected output points, supporting 10–30 V DC operation for reliable control of DC loads such as solenoids, contactors, relays, and indicator devices.

This module is engineered for high-current switching applications, with a total output capacity of 8 A, making it suitable for demanding industrial environments. The electronically protected design helps safeguard outputs against overloads and short circuits, improving system robustness and minimizing downtime. Installed directly into the SLC 500 chassis, the 1746-OB16E enables modular expansion while maintaining consistent performance and predictable behavior in discrete control applications.
