KNX Line Coupler can be used as a line coupler or repeater (for address extension), which can be connected to a main line and a sub line when the device works as a line coupler. A separate power supply including a chock is required for each new line segment and each line will be electrically isolated. Through the line coupler, packet filtering can be carried out between the two lines, reducing the amount of telegrams, preventing interference, and maintaining efficient communication.

The coupler is connected to KNX zone/line to enable zone/line isolation. Data packets can also be filtered to reduce telegram traffic and maintain good communications.
When the device works as a branch coupler, the branch main line and branch sub-line can be connected. When works as a region coupler, the region main line and branch Bus can be connected.
The device can be used as a line coupler or repeater.
6 LEDs display data transmission status and 1 LED for programming status display.
