Line Coupler

The line coupler is used in larger installations to connect KNX lines or areas. The lines/ areas are electrically isolated from each other. At the same time, it is possible to filter out messages in order to reduce the message traffic in a line. The line coupler has bus connection terminals for the main line and subordinate line. The line coupler can also be used within a line as a line amplifier (repeater).
