Description

Brief Product Description

The ABB TC625 (3BSE002224R1) is a specialized coaxial modem designed to provide high-reliability data transmission within the Advant Fieldbus 100 (AF100) network.² It bridges communication between Advant 400 Series controllers and coaxial media via standard CI-series interfaces.

High-Integrity Coaxial Communication

The ABB TC625, identified by part number 3BSE002224R1, serves as a critical hardware link for the Advant Fieldbus 100 (AF100) architecture. This coaxial modem facilitates the seamless exchange of data across coaxial media, ensuring signal integrity for complex DCS environments. It primarily enables connectivity for the Advant Controller 400 Series and AdvaSoft for Windows workstations. By converting digital signals for transmission over coaxial cabling, the TC625 maintains the deterministic performance required for mission-critical industrial automation.

Interface Compatibility and System Integration

Versatility in hardware pairing allows the TC625 to integrate with several ABB communication interfaces. Specifically, the module works in tandem with CI520, CI522, and CI526 interface boards. For instance, when technicians deploy the CI526 interface, they must utilize one or two TC625 modems to establish a functional coaxial media link. While the CI527 interface typically utilizes twisted-pair media, the TC625 remains the standard choice for any AF100 segment requiring the superior distance and noise immunity of coaxial cabling. Furthermore, a TK549 connection cable links the modem directly to the interface board and an SB512 power supply unit, creating a centralized and manageable communication node.

Reliable Data Transmission in Harsh Environments

ABB engineered the TC625 3BSE002224R1 to withstand the electromagnetic challenges of industrial plant floors. The transition to coaxial media via this modem provides enhanced shielding against interference, which is vital for maintaining steady data throughput in high-voltage areas. The module’s robust Swedish construction ensures a long operational life within Distributed Control Systems. Consequently, the TC625 acts as a foundational component for engineers seeking to maintain or expand their AF100 network infrastructure with a focus on stability and high-speed synchronization.
