产品介绍
The Allen-Bradley 1794-OE4 FLEX I/O Analog Output Module is a precision analog output module designed for industrial control systems requiring accurate and stable signal transmission. As part / the FLEX I/O series from Rockwell Automation, it provides reliable 4–20 mA current outputs for interfacing with field devices such as control valves, actuators, and signal converters.
This module features 4 single-ended analog output channels, allowing independent control / multiple process variables. It is well suited for distributed I/O systems where analog signals need to be transmitted over long distances with minimal interference.
Designed for flexibility and ease / integration, the 1794-OE4 supports DIN rail mounting and uses screw terminal connections for secure wiring. Its compact structure and robust performance make it a dependable solution for both process and machine control applications.
