Product Description

The 1769-OF4VI is an isolated analog output module for the Allen-Bradley Compact I/O platform. It provides four differential output channels, each with individual isolation, helping eliminate ground loops and electrical noise in demanding industrial environments.

With 15-bit resolution plus sign and high signal stability, the module is well suited for critical process control loops where signal integrity is essential. Its isolated channel design protects the controller and connected field devices, ensuring reliable analog signal transmission across large industrial systems.

The compact module supports DIN rail or panel mounting, allowing easy integration into CompactLogix-based control cabinets.

Typical Applications

Process Automation
Used in chemical, pharmaceutical, and industrial process plants requiring stable analog signal control.

Noise-Sensitive Systems
Ideal for installations with ground potential differences or high electrical noise.

Industrial Equipment Protection
The isolated channel design protects controllers and field devices from interference generated by heavy machinery.

FAQ

Are the channels isolated from each other?
Yes. Each of the four output channels is individually isolated, preventing cross-talk and ground loop issues.

Is the 120 ms conversion speed suitable for motion control?
The module is designed for process control applications where stability is more important than high-speed response. For fast motion control, a faster analog output module may be required.
