ABB IMAMM03 Infi 90 Analog Master Module
The ABB IMAMM03 is an Analog Master Module designed for the ABB Bailey INFI 90 and Net 90 Distributed Control Systems (DCS). Operating as a central analog interface, the module acquires and processes analog signals from field devices via connected analog slave modules, managing up to 64 individual input channels across industrial process monitoring applications.
Processing Capacity and Architecture
The module incorporates 24 kB of RAM, 36 kB of ROM, and 6 kB of battery-backed RAM (BATRAM) to perform high-speed signal conditioning and A/D conversion. It delivers 16-bit resolution with 15-bit guaranteed linearity across multiple signal types, including high-level analog, thermocouple, millivolt, and RTD inputs depending on slave module configuration. Designed for installation in INFI 90 module mounting units such as the IEMMU01 chassis, the board draws power directly from internal system rails with a maximum total power dissipation of approximately 6.46 W.
