ABB TC625 3BSE002224R1 Advant Fieldbus 100 Coaxial Modem

The ABB TC625 (3BSE002224R1) is a high-performance AF100 coaxial modem that enables deterministic, real-time data exchange between Advant OCS controllers and distributed I/O. It features 1.5 Mbit/s transmission speeds, integrated galvanic isolation, and full support for redundant bus architectures to ensure maximum system uptime.

Product Overview

The ABB TC625 serves as a specialized communication interface module designed for the Advant OCS (Open Control System) environment. This modem operates on the Advant Fieldbus 100 (AF100) protocol, providing a high-speed link that bridges Advant controllers—such as the AC 410 and AC 450—with remote I/O units. By converting logic-level signals into high-frequency pulses suitable for coaxial transmission, the TC625 ensures that process data moves across the network with high deterministic accuracy.

Reliability is a core feature of the TC625 hardware. It includes sophisticated circuitry that manages signal integrity by compensating for potential cable attenuation over long distances. To protect the integrity of the control system, the unit features built-in galvanic isolation, which effectively blocks electromagnetic interference (EMI) and prevents ground loops often found in heavy industrial settings like power plants.

Furthermore, the TC625 is engineered for high-availability architectures. It supports redundant configurations where two modems function in parallel across separate coaxial lines. This dual-path approach ensures that the control system remains operational even if a cable is damaged or a hardware fault occurs, making it a critical component for mission-critical automation tasks.
