ABB DASO110 57120001-AT1 analog output module, 4-channel isolated AO for Advant Master DCS system.

Product Overview

ABB DASO110 57120001-AT1 (also marked DSAO110) is a 4-channel isolated analog output module for ABB Advant Master / MOD300 DCS control system. It converts digital control signals from the controller into standard analog signals to drive field actuators, control valves and positioners. It features high conversion accuracy and channel isolation design, effectively suppressing ground loop interference. It communicates with the Advant controller through the S100 I/O bus, and is widely used as maintenance spare parts for old ABB DCS cabinets in process industries.
