1769-OB32 32-Point Digital Output Module 24V DC | Allen-Bradley

The Original New Allen-Bradley 1769-OB32 32-Point Digital Output Module is a CompactLogix high-density discrete output device designed for 24V DC sourcing applications in industrial automation systems. Featuring 32 solid-state outputs arranged in two isolated groups of 16, this module provides reliable control for solenoids, relays, indicator lamps, and other DC loads in demanding manufacturing and process control environments. Part of the Bulletin 1769 CompactLogix™ I/O platform, it is fully compatible with CompactLogix controllers and MicroLogix 1500 expansion assemblies.
