  • Page 4: Description

    Description Description The Interface KNX B8-TH has eight binary inputs and two additional sensor inputs for temperature or temperature and air humidity. They are used to integrate signals and values from conventional buttons and sensors into the KNX building bus.

  • Page 5: Technical Specifications

    There are unprotected live components inside the device. • National legal regulations are to be followed. • Ensure that all lines to be assembled are free of voltage and take precautions against accidental switching on. Interface KNX B8-TH • Version: 24.08.2016 • Technical changes and errors excepted.

  • Page 6: Installation Location

    Avoid condensation. 2.3. Connection The Interface KNX B8-TH is connected to the KNX data bus with a KNX connection terminal. The physical address is assigned by the KNX software. There is a button with a control LED for this on the device.
