Industrial Overview
The ABB Bailey NTCF22 Termination Unit is a high-reliability interface component used in the INFI 90 Distributed Control System (DCS). It is specifically designed for INFI-Net optic-to-electric communication, enabling seamless conversion between fiber optic signals and electrical signals within industrial automation networks.
This module plays a critical role in maintaining high-speed, noise-immune, and long-distance communication across distributed control architectures. It is commonly used in legacy ABB Bailey installations where robust fiber optic networking is essential for stable process control and data integrity.
