The ABB Bailey NBTM01 is a dedicated Network Bus Termination Module used in the INFI 90 / Net 90 distributed control system (DCS). It is designed to provide proper electrical termination for the system’s communication bus, ensuring signal integrity, impedance matching, and stable high-speed data transmission across the industrial control network.
In distributed automation architectures, improper bus termination can lead to signal reflection, communication errors, and system instability. The NBTM01 eliminates these risks by maintaining controlled network impedance and ensuring reliable communication between controllers, I/O modules, and system nodes. It is widely used in power plants, oil refineries, petrochemical facilities, and large-scale industrial automation systems.
