The coupler connects two KNX data lines and ensures the electrical separation of these lines from one another. The definite functions of the device are defined by addressing and parameterisation.
Line coupler
Connection of a line with a main line. Alternatively with or without filter function. The coupler belongs logically to the subordinate line (here: line).
Area coupler
