Product Overview
The ABB NDBU-85C is a communication branching unit in ABB's industrial drive systems (ACS800 / DCS800), primarily used for the expansion and distribution of the DDCS fiber optic communication network within the system. This module is responsible for distributing high-speed communication signals from the main control unit to multiple drive or control nodes, thereby achieving coordinated control of multiple drive systems.
The NDBU-85C acts as a "communication hub" in large industrial drive systems, ensuring stable, high-speed, and highly interference-resistant data exchange between multiple drive units. It is a crucial network infrastructure component of ABB's high-end drive systems.
