• PN: TC625, Part No: 3BSE002224R1
• Brand: ABB
• Series: Advant Master, MOD300, System 800xA DCS
• Type: AF100 Coaxial Fieldbus Modem

• Function: TC625 is a dedicated signal conversion modem for ABB AF100 fieldbus system. It works with CI520, CI522, CI526 communication interface cards to convert electrical signals into coaxial bus signals, realizing reliable bidirectional transmission of process data, control commands and fault alarm information between central controllers, remote I/O cabinets and monitoring workstations. Adopting coaxial cable transmission, it features strong anti-electromagnetic interference capacity, which is suitable for long-distance bus networking in power plants, petrochemical and other harsh industrial sites.
