Introduction
The ABB Bailey IMASM03 Analog Input Slave Module is a precision analog interface designed for the ABB Bailey Infi 90 Distributed Control System (DCS) family. As part of the modular I/O architecture, this module is responsible for acquiring and conditioning analog signals from field devices—such as transmitters, sensors, and transducers—and relaying accurate, high-resolution measurement data back to the control system for loop logic, monitoring, and HMI display.
Built for industrial environments, the IMASM03 ensures reliable analog signal capture and integration with master modules, contributing to tight process control, improved diagnostics, and consistent operational performance.
