System information
This device is a product of the KNX system and complies with the KNX directives. Detailed
technical knowledge obtained in KNX training courses is a prerequisite to proper understanding.
The function of this device depends upon the software. Detailed information on loadable soft-
ware and attainable functionality as well as the software itself can be obtained from the
manufacturer´s product database. Planning, installation and commissioning of the device are
carried out with the aid of KNX-certified software. The latest versions of product database and
the technical descriptions are available on our website.
Intended use
- Establishes a data link between two KNX lines and ensures electrical separation between
these lines
- To be operated by addressing as a line coupler, backbone coupler, or amplifier
- Installation in small distributors on a DIN rail according to EN 60715
Application areas
Line coupler LK: Phys. address X.Y.0
Connection of a line with a main line (HL). Alternatively with or without filter function. The cou-
pler is logically assigned to the subordinate line.
Backbone coupler BK: Phys. address: X.0.0
Connection of a main line (HL) with a backbone line (BL). Alternatively with or without filter func-
tion. The coupler is logically assigned to the subordinate line.
Amplifier V: Phys. address X.Y.Z
Preparation and repetition of telegrams on a line, no filter function. Division of a line into max. 4
independent line segments => max. 3 line amplifiers connected in parallel per line (FIGURE 2).
Each line segment requires a separate power supply (SV) including choke (DR).
