Product Overview: 

The ABB 81EB02 is an analog output module designed for use in the ABB Symphony Harmony/INFI 90 Distributed Control System (DCS). This module converts digital signals from the controller into analog current signals (typically 4–20 mA), which are then sent to field devices such as control valves, I/P converters, and actuators. The 81EB02 is commonly used in critical process control applications requiring high reliability and precision.
