The ABB Bailey NAMM02 is an enhanced Analog Master Module designed for the INFI 90 / Net 90 distributed control system (DCS). It functions as a central analog signal coordination unit, responsible for managing, organizing, and optimizing multiple analog input and output signals across industrial automation systems.
Compared with earlier NAMM series modules, the NAMM02 offers improved signal stability, better noise immunity, and more efficient system-level analog data handling. It is widely used in power generation plants, oil refineries, petrochemical facilities, and continuous process industries, where precise analog signal management is essential for operational safety and efficiency.
