Product Introduction
The Allen-Bradley 1794-OF4I FLEX I/O Isolated Analog Output Module is a high-performance analog output module engineered for precision control in demanding industrial environments. As part of the FLEX I/O series from Rockwell Automation, it provides flexible multi-range analog outputs with built-in isolation, ensuring reliable and noise-resistant signal transmission.
This module offers 4 independently controlled output channels with 16-bit resolution, delivering high accuracy and smooth signal control. It supports a wide range of output signals including current and voltage modes, making it suitable for diverse field devices such as control valves, actuators, and variable speed drives.
With integrated channel isolation, the 1794-OF4I effectively protects the control system from electrical interference, ground loops, and field-side disturbances. Its compact DIN rail-mounted design and compatibility with FLEX I/O terminal bases make it easy to deploy in distributed automation architectures.
