The ABB Bailey NBCM01 Bridge Communication Module is an industrial-grade communication interface designed to enable data transfer and protocol bridging between different segments within the ABB INFI 90 or Symphony DCS (Distributed Control System). It plays a critical role in distributed automation architectures by facilitating seamless communication between control modules, workstations, and I/O networks located in separate physical locations or different network domains.

Built for high reliability and robustness, the NBCM01 supports real-time deterministic data exchange while maintaining system integrity and performance. Whether used for segmenting control strategies, integrating legacy and modern systems, or expanding network topologies, the NBCM01 ensures efficient communication over extended distances.
