High Current Output Module 1769-OB8 | Allen-Bradley

Product Overview
The Allen-Bradley 1769-OB8 is a high-current digital output module designed for reliable signal switching and control in CompactLogix and compatible automation systems. It supports 18 output points, organized in four-point groups, and provides robust electrical isolation between channels and groups. The module operates with 24 VDC inputs, handles short-term surge currents up to 4 A for 10 ms, and is optimized for DIN rail or panel mounting. Its compact footprint and low heat dissipation make it suitable for distributed I/O configurations, while maintaining high reliability in industrial environments.
