ABB TC630 3BSE002253R1 Optical Modem
Description
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.
