ABB IMAMM03 analog master module

1. Product Overview

The ABB IMAMM03 Analog Master Module is a key component of the ABB INFI 90 Distributed Control System (DCS), designed to manage and process analog input/output data.
It functions as the master analog signal controller, coordinating data acquisition, signal conversion, and communication with subordinate analog modules (e.g., IMAOM, IMASI, IMASM).
With high sampling accuracy, robust isolation, and stable performance, the IMAMM03 ensures precise control and reliable signal integrity in industrial environments.
