ABB IMASO01 Bailey Infi 90 Analog Output Slave Module

Description

The ABB IMASO01 is a high-reliability Analog Output Slave module developed for the Bailey Infi 90 and Network 90 Distributed Control Systems (DCS). This module serves as the primary interface for translating digital control commands from the master processor into continuous analog signals required by field actuators, valves, and positioners. Supporting 14 independent output channels, the IMASO01 ensures that modulated control variables are delivered with high precision and stability. It is an essential component for closed-loop regulatory control in heavy industrial environments such as power plants, water treatment facilities, and chemical processing units.
