Allen-Bradley 1769-OF4CI Compact I/O Analog Output Module

The Allen-Bradley 1769-OF4CI is a Compact I/O analog output module from the CompactLogix family, designed to provide 4 isolated differential current outputs for precise signal control in industrial automation systems. With support for both 0–20 mA and 4–20 mA output ranges, high resolution and individual channel isolation, it delivers reliable and accurate current signals to actuators, valves, and other field devices in process and machine control applications.

This module is ideal for use with CompactLogix and MicroLogix 1500 controllers and features 16-bit resolution, conversion rates up to ~110 ms, robust isolation, and flexible mounting options such as DIN-rail or panel installation.
