Allen Bradley 1746-OB6EI Output Module

Product Introduction

The Allen-Bradley 1746-OB6EI is a digital DC output module designed for the SLC 500 control system. It provides 6 electronically protected digital output points, making it suitable for applications that require reliable control of a limited number of DC loads with enhanced protection features.

This module is engineered to deliver stable and repeatable output performance while protecting both the module and connected field devices from electrical faults. The electronically protected outputs help mitigate the effects of overloads, short circuits, and wiring errors, improving overall system reliability. Installed directly into the SLC 500 chassis, the 1746-OB6EI supports modular system expansion while maintaining consistent operational behavior in industrial environments.
