Product Overview

The TC625, cataloged as 3BSE002224R1, is a high-performance coaxial communication modem designed for the ABB Advant Fieldbus 100 (AF100) network. This module serves as the essential physical layer interface, converting electronic bus signals into high-frequency transmissions suitable for coaxial media. It is primarily utilized to link Advant Controller 400 series processors and AdvaSoft engineering stations across long distances. By utilizing the TC625, industrial systems achieve superior signal immunity against electromagnetic interference (EMI) and maintain high-speed data integrity throughout the plant floor. This modem is a critical component for both simplex and redundant bus architectures, ensuring constant availability for distributed control operations.
