  DESCRIPTION
Product name: Area / Line coupler
Design: REG (rail-mounted device)
Article no.: 1023 00
ETS search path: Gira Giersiepen / System components / line coupler / area/line coupler DRA
Functional description:
The area/line coupler interconnects two KNX / EIB lines into a logical function area ensuring at the same the
electrical separation between these lines. Each bus line of a KNX / EIB installation can thus be operated
electrically independently from other bus lines.
The exact function of the device is determined by the selected parameterization and by the physical address.
The device can be used as an area coupler, line coupler or line repeater for implementing line segments in
existing new KNX / EIB 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) optionally with and 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 an area coupler (AC) (physical address: X.0.0)
Connection of a subordinate line (main line) to a higher-order line (backbone bus) optionally with and
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 realized. 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
