Overview

The ABB TC630 optical modem is a communication interface module used in Advant Fieldbus 100 (AF 100) networks. It facilitates coaxial-to-optical or optical-to-coaxial signal conversion, enabling flexible media transitions in distributed control systems.

This functionality is especially useful in ABB Advant Master Process Control Systems, where long-distance and noise-resistant communication is critical. Its compact design and industrial-grade reliability make it suitable for substation automation, process control, and factory communication backbones.

The module operates on a 24 VDC supply and supports ST-style optical connectors. It is exempt from the EU RoHS directive under Article 2 (4), making it suitable for legacy systems and specialized industrial applications.

Technical Data

Typical Applications

The TC630 is commonly used to extend communication links across long distances in ABB Advant Master control systems. Examples include:

• Power plants: reliable data exchange between remote I/O stations and central controllers.

• Chemical facilities and manufacturing lines: noise-resistant communication over mixed coaxial and fiber networks.

• Retrofit projects: upgrading coaxial infrastructure to fiber without replacing the entire network.

Engineers value its compact size, low power consumption, and robust signal integrity in electrically noisy environments.
