KSC-02L is a KNX Secure Line Coupler/Repeater, providing a bi-directional data connection between two KNX TP lines/areas.

The KNX TP main line and sub line are coupled, with a galvanic isolation between them. Using the TP coupler action, KSC-02L can be used to connect several TP lines, and as an area coupler to connect several TP areas, or different KNX TP installation systems via a TP backbone.

Telegram filtering is accomplished according to the installation place in the hierarchy and according to the built-in filter tables for group communication. For detailed diagnosis, all operational modes are shown by a duo-LED display.

Using the TP repeater application, KSC-02L is able to extend a KNX TP line providing unfiltered data transfer and galvanic isolation between segments.

Up to four-line segments can form a single KNX TP line by connecting three KSC-02L line repeaters. Each line segment requires its own KNX bus power supply unit to ease commissioning and troubleshooting.
