REGOLO KNX line/area coupler allows coupling of a KNX bus main line with a KNX bus secondary line. The device provides galvanic isolation between
the two connected lines. Thanks to its flexibility, the coupler can be used as a line coupler to connect a secondary line with a main line or as an area
coupler to connect a main line with a backbone line. The main task of the device is filtering the traffic according to the installation position in the hierarchy
or according to the built-in filter tables for group-oriented communication. The device provides support for long messages (up to 250 bytes) and a
configurable button for special functions activation which are helpful during installation, run time operation and troubleshooting. 6 LEDs accurately display
the bus status on each line. This helps identifying common communication problems due to bus load or retransmissions on both lines. The device is
powered by the KNX bus line with SELV voltage 30 Vdc and does not require any auxiliary power supply.
