Description
Product Overview
The ABB NDBU-95C 64008366D is an industrial-grade DDCS (Drive Device Communication System) optical branching unit, engineered to distribute high-speed fiber-optic signals across multiple devices in automation, drive, and control networks. Designed as a star topology splitter, this unit takes a single high-integrity optical input and reliably fans it out to nine independent output channels operating at up to 10 Mbps, minimizing signal degradation in distributed systems.
Built for robust performance in challenging industrial environments, the ABB NDBU-95C 64008366D simplifies network architecture and enhances communication resilience by leveraging fiber-optic immunity to electrical noise and interference. Typical installations include multi-drive control systems and large-scale automation networks where reliable data exchange and scalable connectivity are paramount.
The ABB NDBU-95C 64008366D delivers dependable performance and seamless integration with ABB DDCS networks, offering a compact, DIN-rail mountable solution that supports expansive control topologies with minimal complexity.
