The line coupler is used in larger installations to connect KNX lines or areas.
The lines or areas are galvanically isolated from one another. Telegrams can be filtered to simultaneously reduce the telegram traffic between lines or areas.
With ETS the complete group address range of the main groups 0…31 can be filtered.
Within a line, the LK/S 4.2 can also be used as a line amplifier (repeater).
The device supports long frames (from > ETS5) and KNX Data Secure communication.
KNX Data Secure telegrams are processed, filtered, forwarded, or blocked depending on settings
