Description

The line coupler is used in larger installations to connect ABB KNX lines or areas. The lines or areas are galvanically isolated from one another. Filter tables can be used to reduce the telegram traffic between lines or areas. Within a line, the LK/S 4.1 can also be used as a repeater. Connection to main and subline via bus connection terminals.

Different application programs are available with the LK/S 4.2 for ETS 3 and ETS 4. Some of the functions for the ETS 4 are not available in the applications for the ETS 3.

In ETS 3, there is a separate application for coupling and for repeating (Couple/1.x or Repeat/1.x), in ETS 4, there is a common application (Couple Repeat/2.x). All applications are upwards compatible, i.e.:

  • The old applications of LK/S 4.1 can be loaded in the LK/S 4.2 (ETS 3). This is particularly useful if in an existing project an LK/S 4.1 has to be replaced by an LK/S 4.2.
  • The applications Couple/1.x or Repeat/1.x can be loaded in the LK/S 4.2 via the ETS 3 or the ETS 4.
  • The new application Couple Repeat/2.x with extended functional range is only available for the ETS 4.
