Allen Bradley 1746-OBP16 SLC 500 Digital DC Output Module

Product Introduction

The Allen-Bradley 1746-OBP16 is a digital DC output module specifically designed for the SLC 500 programmable controller platform. It provides reliable control of DC-powered field devices with precise switching capabilities in industrial automation systems.

This module features 16 independent output channels, delivering 6.4 A total with individual point capability of 250 mA, suitable for low-power DC and AC-controlled devices. It supports 20.4–26.4 VAC input for operation in applications requiring pulsed or controlled AC-powered DC outputs. The 1746-OBP16 is optimized for efficient control of solenoids, indicators, relays, and other field devices requiring low-current DC actuation.

Engineered for industrial control cabinets, the OBP16 combines high output density with solid-state reliability, providing predictable switching, electrical isolation, and seamless integration with SLC 500 processors. This module is ideal for applications that demand precise control, minimal electrical noise, and compact installation.
