Allen Bradley 1756-OB16 ControlLogix Digital Output Module

Product Introduction

The Allen-Bradley 1756-OB16 is a ControlLogix digital output module designed to provide reliable DC output control for industrial automation systems. As a standard member of the ControlLogix I/O family, it integrates tightly with Rockwell Automation controllers and chassis, offering deterministic output control and consistent system behavior.
This module is widely used in applications that require stable DC signal switching, high channel density, and seamless controller integration within complex control architectures.

The 1756-OB16 features a 16-channel output configuration, making it suitable for systems that need to control multiple field devices from a centralized ControlLogix platform. Its design emphasizes electrical reliability, ease of configuration, and long-term operational stability in industrial environments.
