Product Introduction
The ABB Bailey IMASM01 Analog Input Slave Module is a critical component in ABB’s INFI 90 Distributed Control System (DCS). It serves as a slave interface that enables the reliable transmission of analog input signals from field devices to the system’s multifunction processors and controllers. Designed for high-accuracy process control applications, this module is especially useful in industrial environments where precision and stability are crucial.
This module reads analog inputs, converts them to digital signals, and communicates them via the control bus to the associated processing units. It is widely used in systems requiring redundant and distributed architecture, ensuring continuous, uninterrupted monitoring of analog signals such as temperature, pressure, flow, and level.
