The Theben Line Coupler S KNX is a
modular installation device with a module
width of 2 space units.
It is used as a line or area coupler or as a
repeater.
As a line coupler, the Line coupler S
connects a line with a main line, as an
area coupler it connects a main line with
an area line. It provides electrical
isolation in this way.
If required, the Line coupler S filters
telegrams and only routes the telegrams
intended for other lines. It is possible to
route or block all telegrams for
diagnostic purposes.
