Introduction
The ABB Bailey IMAS102 Analog Input Slave Module is a high-performance I/O component designed for the ABB Bailey Infi 90 Distributed Control System (DCS). It functions as a dedicated interface for multiple analog field signals, collecting precise voltage or current inputs from sensors and transmitters and relaying them to the analog master module for processing. Its industrial-grade design ensures stable acquisition of analog process variables including flow, level, temperature, and pressure—making it a trusted choice in large-scale automation environments.
Infi 90 systems rely on Analog Input Slave Modules like the IMAS102 to bridge raw field data and the control logic, ensuring accurate measurement interpretation without burdensome wiring overhead. Its compact, modular form factor fits seamlessly into standard module racks and backplanes.
