The ABB Bailey NAMM01 is an Analog Master Module used in the INFI 90 / Net 90 distributed control system (DCS). It is designed to manage, process, and coordinate multiple analog input and output signals within industrial automation systems.
Positioned as a core interface module in Bailey’s legacy architecture, NAMM01 plays an important role in signal acquisition, conditioning, and system-level analog data management. It is widely used in power plants, oil refineries, petrochemical facilities, and heavy industrial process control systems, where stable analog signal handling is essential for safe and continuous operation.
This module is often regarded as a central component for analog signal integration within ABB Bailey control environments.
