Specification

SEODescription

The **1769-OF4 Module**, part of the Allen-Bradley OF4 series, is a 4-Ch Analog Output module designed for industrial automation systems. It provides four isolated voltage or current output channels, supporting configurable ranges such as 0–10V, ±10V, 0–20 mA, and 4–20 mA. The module integrates seamlessly into the CompactLogix platform, connecting directly to up to 30 modules via a 1769 backplane. It operates within a 10–30V DC power range and withstands temperatures from -20°C to 60°C, making it suitable for harsh environments. Commonly used in manufacturing, process control, and energy industries, its key advantages include high resolution (16-bit), flexible configuration via RSLogix 5000 software, and robust isolation for noise reduction. A limitation is its dependency on compatible controllers for full functionality.
