Product Overview
The ABB NDBU-95C 64008366 is a specialized network distribution and bus interface unit designed for ABB's legacy MasterView and industrial IT operator workstation environments, particularly in power generation, transmission, and heavy industry control systems deployed from the late 1990s to the early 2010s. It serves as a critical infrastructure component by providing reliable, electrically isolated communication interfaces between redundant operator stations, engineering workstations, and plant-level Advant controllers (AC 160/AC 450) or MasterBus 300/330 field networks. The unit ensures deterministic data exchange in serial and proprietary fieldbus topologies, even under high electrical noise conditions common in substations or turbine halls, enabling synchronous HMI updates, alarm propagation, and historical data recording.
