The ABB Bailey NBIM02 is an enhanced Network Bus Interface Module used in the INFI 90 / Net 90 distributed control system (DCS). It is designed to manage high-speed communication between controllers, I/O subsystems, and networked automation devices, ensuring stable and synchronized data exchange across industrial control architectures.
Compared with earlier NBIM versions, the NBIM02 delivers improved communication stability, stronger noise immunity, and more efficient data handling performance. It is widely deployed in power generation plants, oil refineries, petrochemical facilities, and large-scale industrial automation systems, where reliable real-time communication is essential for safe and continuous operation.
