4-channel Universal Interface – EM KNT 001

4-channel Universal Interface


  • Universal Interface with 4 binary inputs and 4 LED outputs.
  • The Universal Interface has 4 channels which can be parameterised as inputs or outputs, e.g. for
    connection of conventional pushbuttons, free-voltage motion detectors, etc.
  • The interface can evaluate at its potential-free inputs up to 4 pushbutton/switch states with a
    common reference potential and send the corresponding telegrams.
  • The telegrams may be for switching or dimming, blind/shutter control, value transmitter applications
    (light level, temperature,…), light scene control or pulse counting.
  • As an alternative, the four channels can control four LEDs as independent outputs.
  • The outputs are protected against short circuits, overload and wrong polarity.
  • This device is flush mounted in a universal box, behind the pushbutton/switch.
  • Dimensions: 38 x 42 x 15mm.
  • Programming and commissioning by ETS4 or later.
