Allen Bradley 1769-OF4 4-Channel Analog Output Module 1769OF4

Description:

The Allen Bradley 1769-OF4 Analog Output Module is used in CompactLogix and MicroLogix 1500 systems for converting digital control signals into analog outputs. Commonly installed in 1769 Compact I/O chassis within industrial automation systems for controlling field devices such as drives, valves, and actuators. Maintenance teams, OEMs, and system integrators use this module for system expansion, retrofit, or replacement of analog output modules.

Applications:

The Allen Bradley 1769-OF4 is designed for industrial automation applications requiring precise analog signal output to control process equipment. It is widely used in manufacturing lines, water and wastewater treatment plants, HVAC systems, and process industries where accurate voltage or current signals (e.g., 4–20 mA or 0–10 V) are required. The module enables reliable control of variable frequency drives, control valves, and actuators, ensuring stable and efficient operation within PLC-based systems.
