The ABB Bailey NSBM01 Superloop Bus Module is a communication interface module used in the ABB Bailey INFI 90 / Net 90 Distributed Control System (DCS). It is responsible for managing high-speed data communication across the system’s Superloop network, enabling reliable exchange of control and process information between controllers, I/O modules, and system nodes.
In large-scale industrial automation systems, stable and deterministic communication is essential. The NSBM01 provides a backbone communication function, ensuring synchronized data transfer and system-wide coordination across distributed control elements.
It is widely used in legacy ABB Bailey installations in power generation, petrochemical, and process industries where robust network communication is required for continuous operation.
