ABB EIB / KNX Optical Fibre Interface, MDRC (4 DIN)
The device is used to couple two sections of an bus line using an optical fibre link. Ideal for bridge longer distances or to avoid having to implement lightning and overvoltage protection when laying cables between buildings. Two devices are needed to complete a transmission link.
The device is used to couple two sections of an EIB line using optical fibres in order to bridge greater distances and to reduce the amount of lightning and overvoltage protective equipment when laying cables across buildings. An EIB power supply must be provided for both EIB sections.
Two devices are required to set up a transmission link. These are connected to an existing optical fibre installation by means of a 2 m long patch cable (included with supply). Signals are transmitted by two optical fibres that are suitable for transferring 850nm signals. It is also possible to connect them directly with prefabricated standard cables.
