Allen-Bradley 1769-OB16 CompactLogix 16 Point 24V DC Output Module

Product Description

The 1769-OB16 is a CompactLogix digital output module from Allen-Bradley designed for high-speed switching of 24V DC field devices. It provides 16 sourcing outputs within a single-slot form factor, enabling dense I/O configuration in CompactLogix control architectures.

This module operates within a 20.4–26.4V DC range and is optimized for fast response applications where precise output timing is required. Its solid-state design ensures consistent performance and reduced maintenance compared to mechanical relay-based outputs.

The 1769-OB16 supports direct integration into CompactLogix racks with DIN rail or panel mounting options, making it suitable for compact machine control systems and distributed automation layouts.
