The ABB Bailey IMRAE11 is an Analog Input Module used in the INFI 90 distributed control system (DCS). It is designed to acquire and condition analog signals from field instrumentation such as pressure transmitters, temperature sensors, flow meters, and other process measurement devices.
This module plays a critical role in industrial automation by converting real-world analog signals into digital data that can be processed by ABB Bailey controllers. It is widely used in power generation, chemical processing, oil & gas, and heavy industrial systems, where accurate signal acquisition and system stability are essential.
