Line backbone coupler

The area / line coupler connects two KNX lines with regard to the regulation of the data transmission and ensures a galvanic separation between the lines. This means that each KNX line can be electrically operated independently of the others. For each line, main line or area line a separate KNX power supply is required. Line couplers or area couplers are needed to create greater KNX topologies with a variety of KNX devices. The smallest topology is a line which is fed by means of a KNX power supply. A single line does not require a line coupler. Theoretically, 255 KNX devices could be integrated in a single line. Due to the average power reqiurement of KNX devices, cable lengths and other limit value definitions 64 KNX devices, i.e. devices with bus coupler, are defined as maximum per line. For a standard single-family house and optimum planning this is usually sufficient. When using a 640mA power supply, the device number may be significantly increased by means of line amplifiers. This function can also be carried out by line / area couplers (see product description). The newly constructed sub-line receives its own KNX power supply and is, for galvanic separation, connected via line amplifier with the existing line. Since the ETS (Engineering Tool Software) allows more than 64 devices per line, the devices of the sub-line can be considered as if they were part of the overlying line. For extensions, another line is usually constructed with a KNX 640mA power supply. This line is coupled to the first line via line coupler. The line connecting the line couplers is called main line. Naturally, another 64 devices can be connected to the main line. Up to 15 lines can be connected to this main line, which is the maximum value for one area. Extensions are again carried out by means of a line coupler (area coupler, depending on the assignment of the physical address and parameter setting). The line connecting areas with each other is the backbone line. Thus, up to 15 areas are possible with tens of thousands of KNX devices. If there is a network connection between buildings or building parts, KNX IP routers can connect two KNX installations via routing protocol. A KNX IP router can provide the protocols Routing and Tunneling in parallel, a KNX IP interface, however, only tunneling. eibabo offers EIB KNX line and area couplers, KNX line amplifiers KNX IP interfaces KNX IP routers (see also Catalog interface media gateway and data interface) by the manufacturers ABB, Berker, Busch-Jaeger, EIBMARKT, Gira, Hager , Jung, Lingg & Janke, MDT, Merten, Siemens and Theben.
