ABB DSAO120 57120001-EY 8-channel analog output module for Advant Master MOD300 S100 I/O DCS system.

Product Overview

ABB DASO120 (DSAO120) 57120001-EY is an 8-channel analog output board belonging to ABB Advant Master / MOD300 S100 I/O series. It receives digital control signals from the controller and converts them into standard analog current or voltage signals to control field regulating valves, actuators and positioners. It adopts 12-bit signed conversion with high precision, supports bipolar signal output, and communicates with the main controller via the S100 I/O bus. It is a widely used maintenance spare part for legacy ABB DCS control cabinets in process industries.
