Product Introduction
The ABB Bailey NBIM02 Bus Interface Module is a key communication element used within ABB’s INFI 90 and Symphony process control systems. Functioning as a vital bridge, the NBIM02 manages the bidirectional communication between central processors and the distributed input/output subsystem across the control network.
Designed for environments where reliable, high-speed data transmission is non-negotiable, the NBIM02 excels in redundancy-supported configurations, ensuring that control systems maintain operational continuity, even in the presence of faults or disturbances. The module serves as a replacement or upgrade to the NBIM01, providing enhanced diagnostic and fault handling capabilities, while retaining complete compatibility with existing Bailey system infrastructure.
