Performance as a line or area capler: This device must be used to connect software (by applying filtration) and electrically isolating the KNX system to a new line (Line) or Area. In this case, you can manage a Filter Table by setting the Filter Table between the two lines or areas.

Performance as a developer: In order to increase the KNX devices of one line to a maximum of 3 sub-lines, in each line it is possible to connect a maximum of 64 KNX devices (ie, to install a maximum of 256 devices in one line).
