KNX Line Coupler

Product code: 102300
The area/line coupler connects two KNX lines to each other for data transfer and ensures an electrical isolation between these lines. Each bus line of a KNX installation can be operated electrically independently of the other lines. A separate power supply is required for each line (area line, main line, line) or each line segment.

Description

The exact function of the device is determined by the selected parameterisation and by the physical address. The device can be used as a backbone coupler, line coupler or line repeater for implementing line segments in existing and new KNX installations.

Used as a line coupler (LC) (physical address: X.X.0):

Connection of a subordinate line (line) to a higher-order line (main line) with or without filter function for group  communication. The coupler is logically assigned to the
subordinate line by way of its physical address. The coupler is supplied with power from the higher-level line (main line).

Used as a backbone coupler (BC) (physical address: X.0.0):

Connection of a subordinate line (main line) to a higher-order line (backbone bus) with or without filter function for group communication. The coupler is logically assigned to the subordinate line by way of its physical address. The coupler is supplied with power from the higher-level line (backbone bus).

Used as a line repeater (LR) (physical address: X.X.X):

By using a line repeater, a line (64 devices max.) can be expanded by a further line segment (further 64 devices). With a maximum of 3 line repeaters in parallel per line, the highest maximum number of 256 devices in a line (including LRs) can then be realised. The line repeater has no filter tables so that all group telegrams will always be transmitted unfiltered. 

Each line (backbone bus, main line, line) or each line segment requires a separate power supply.
