Allen-Bradley 1769-OF4CI 4-Channel Analog Output Module

The Allen-Bradley 1769-OF4CI is a four-channel current-output module for CompactLogix systems, delivering four independent 4–20 mA outputs to drive valves, actuators, and other analog-controlled field devices. Designed for use in CompactLogix and MicroLogix 1500 control panels, it mounts on a DIN rail and interfaces with the 1769 Compact I/O backplane, with channel-to-system isolation to improve noise immunity. It uses high‑resolution digital-to-analog conversion and is powered by the 1769 system power supply, with four channels suitable for precise industrial control under industrial-rated operating conditions and installation within a control enclosure. Common replacements include the 1769-OF4, 1734-OE4C, and 1756-OF4, making it a practical option for replacement of failed analog output modules.
