| Description | ||
The ABB NDBU-85C is a fiber optic branching unit specifically designed for the ABB DDCS (Direct Digital Control System) network. It plays a crucial role within ABB's high-performance ACS800 series of AC drives and the DCS800 and DCS800-EP DC drive systems. In essence, it's a device that allows fiber optic communication signals to be distributed and converged to multiple paths, significantly enhancing the scalability and reliability of complex drive system networks. | ||
Role of ABB FAU810
DDCS Network Expansion: The NDBU-85C is a key component within the DDCS network. DDCS is ABB's proprietary high-speed fiber optic communication protocol used for fast, synchronized data exchange between drives.
Enabling Star Connection: Traditional fiber optic communication typically involves point-to-point or ring connections. The introduction of the NDBU-85C enables DDCS networks to adopt a "star" topology.
High-Speed Communication Support: The NDBU-85C supports fiber optic channels of different speeds. includes multiple 5Mb fiber optic output channels accommodate the communication rate requirements
Signal Branching and Amplification: It receives a signal from one fiber optic input, then copies and amplifies it before distributing it through multiple fiber optic output ports.
