Overview

The ABB DSDO131 is a digital output unit designed for ABB’s Advant Master Process Control System, providing reliable handling of discrete output signals in industrial automation environments. It features 16 relay-based channels, each capable of switching voltages from 0 to 240V AC/DC, making it suitable for actuators, solenoids, alarms, and other field devices.

Engineered for high-load switching and electrically noisy environments, the DSDO131 includes galvanic isolation for safe, interference-free operation.

For example, in a turbine control system, the DSDO131 can activate trip relays, signal lamps, or alarms based on real-time logic from the DCS.

Technical Data

Typical Applications

• Power Plant Control Systems: Activates trip coils, alarms, and interlocks in turbines and boilers.
