KNX Area and Line Coupler
The KNX Area and Line Coupler connects two KNX lines to form a shared logical functional area. At the same time, galvanic isolation ensures that the connected bus lines can operate electrically independently of each other.
The device enables clear structuring, segmentation and expansion of KNX installations. Telegram traffic between the lines can also be selectively filtered.
Typical Applications
The Area and Line Coupler is suitable for applications such as:
- connecting different floors or building areas,
- separating lighting, shading, heating and other building systems,
- segmenting larger KNX installations to reduce bus traffic,
- electrically isolating indoor and outdoor areas,
- gradually expanding existing KNX installations,
- separating individual units, such as offices, apartments or hotel rooms.
EXAMPLE: Office Building
A typical example is a multi-storey office building in which each floor has its own KNX line. The Line Coupler connects these lines to the main line while ensuring that an electrical fault on one floor does not affect the other areas of the building.
Use as a KNX Secure Proxy
The device can be configured as a KNX Secure Proxy. This enables communication between KNX Data Secure-capable devices and devices without KNX Data Secure support, even when they are located on different lines or segments.
This is particularly useful when modernising existing KNX installations. New KNX Data Secure-capable components can be gradually integrated into an existing installation with conventional KNX devices, without having to replace all devices at once.
Use as a KNX Secure Bridge
By using two devices together, a KNX Secure Bridge can be established between two unencrypted KNX lines or segments.
This solution is suitable, for example, for securely connecting physically separate parts of a building complex, such as a main building and an outbuilding, a production hall or an underground car park. The local lines can continue to operate without encryption, while communication across the connecting section is protected.
