Overview

The ABB DSAO120 is an analog output module for the Advant Master Process Control System, providing high-precision signal generation in industrial automation. It features 8 independent channels, each capable of delivering ±10V voltage or ±20mA current signals, making it suitable for valve control, drives, and other analog-driven equipment.

With 12-bit resolution and 0.05% accuracy, the DSAO120 ensures reliable, precise output across demanding operating conditions. Its rugged design and wide temperature range allow deployment in power plants, chemical facilities, and industrial process lines.

For example, in a steam turbine control system, the DSAO120 outputs analog signals to modulate valve positions based on real-time process feedback.
