ABB DSAO120 Precision Control Board for DCS Systems

Description

TheABB DSAO120is ananalog output modulefor theAdvant Master Process Control System, providinghigh-precision signal generationin industrial automation. It features8 independent channels, each capable of delivering±10V voltageor±20mA current signals, making it suitable forvalve control, drives, and other analog-driven equipment. With12-bit resolutionand0.05% accuracy, the DSAO120 ensures reliable, precise output across demanding operating conditions. Its rugged design and wide temperature range allow deployment inpower plants, chemical facilities, and industrial process lines. For example, in asteam turbine control system, the DSAO120 outputs analog signals to modulate valve positions based on real-time process feedback.
