KNX TP LineCoupler 650 connects two KNX segments (for example, a KNX line with a KNX area). It has a very compact design. The device has a filter table (8K bytes) and ensures a galvanic isolation between the lines. The coupler is compatible with the ETS® software from ETS4.2. The buttons on the front panel allow disabling the telegram filter for testing purposes. The LEDs indicate the operating status and communication errors on the bus.
