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.
