KNX line coupler– HDL Automation

The KNX line coupler from HDL Automation can be used as a line coupler or repeater (for address extension), which can be connected to a main line, and a sub line when the device works as a line coupler. A separate power supply including a chock, is required for each new line segment, allowing each line to be electrically isolated. Through the line coupler, packet filtering can be carried out between the two lines, reducing the amount of telegrams, preventing interference, and maintaining efficient communication.

Features 
  • The coupler is connected to KNX zone/line to enable zone/line isolation. Data packets can also be filtered to reduce telegram traffic and maintain good communications;
  • When the device works as a branch coupler, the branch main line and branch sub-line can be connected. When works as a region coupler, the region main line and branch Bus can be connected;
  • The device can be used as a line coupler or repeater;
  • Includes 6 LEDs display data transmission status and 1 LED for programming status display.
 
Advantages 
  • Improved communication efficiency: reduces telegram load through filtering, avoiding unnecessary traffic propagation;
  • Enhanced network stability: electrical isolation prevents fault propagation between KNX segments;
  • Scalable architecture: enables structured expansion of KNX systems without performance degradation;
  • Diagnostic visibility: LED indicators support commissioning and troubleshooting;
  • Flexible deployment: a single device supports multiple roles, reducing component diversity and simplifying specification.
 
Applications
  • Hotels and hospitality environments;
  • Industrial building automation systems;
  • Medium and large KNX installations;
  • Office buildings and commercial infrastructures;
  • Smart residential complexes.
