ABB 6631993A3 Infi-90 Bus Interface Module Assembly

ABB 6631993A3 Infi-90 Bus Interface Module Assembly (INBIM02) is the ABB Bailey BIM02 device that serves as the essential communications gateway between the INFI-90 Module Bus and the Plant Loop within ABB Symphony/INFI-90 distributed control systems. The BIM02 provides the principal interface for INFI-90 processes to exchange real-time data with module-bus controllers and field I/O across the Plant Loop, enabling deterministic, synchronized operation in complex process environments. The assembly is designed for installation in an INFI-90 rack and is upward compatible with the NLIM02/NBIM02 families, allowing interoperability with older Plant Loop configurations. In typical configurations, the INFI-90 module bus network accommodates multiple controllers, with documentation describing support for up to about 30 controllers on the Module Bus. Applications span heavy industry process control, including power generation facilities and refinery automation, where Symphony/INFI-90 architectures coordinate distributed control tasks. The 6631993A3 designation identifies the Bus Interface Module Assembly used within ABB Symphony ecosystems to connect and manage communications between the Module Bus and the Plant Loop.
