Technical data
Further information 


  • 12x digital inputs 24VDC (also suitable for use as frequency inputs e.g. In combination with a wind sensor)
    • Minimum pulse width: 3ms
    • Maximum frequency: 150Hz
    • Accuracy: +/- 1Hz
    • Input resistance: 10kΩ
  • The 24VDC supply on the digital inputs is rated at 100mA, it is not intended for high loads.
  • 4x analogue inputs
    • 0 – 10VDC with 10 bit resolution
    • Can also be used as digital inputs (up to 24VDC): < 1V equivalent to logic 0, i.e. Off ; 1 – 10V equivalent to logic 1, i.e. On)
    • Input resistance: 10kΩ
  • 8x digital outputs (relays) 250VAC 5A at cosφ=1, 30VDC 5A
    • (for large loads use a coupling relay)
  • 4x analogue outputs 0 – 10VDC
    • Maximum 20mA output load
  • Dimensions: 156 x 88 x 57mm (T9 housing)
  • Power consumption without relays: 60mA
  • Power consumption with all relays: 120mA
  • Maximum total power loss: 7.8W
  • Protected against excessive voltage at the relay
  • Protection: IP20
  • Operating Temperature: 0 to 50°C
  • Safety shutdown: If the CPU temperature increases over 87°C, all the digital outputs are turned off. Once the temperature drops below 72°C, the respective digital outputs are turned on. The CPU temperature is updated on startup and if there is a temperature change of more than 5°C.
 When calculating the number of lights that can be powered on one relay you MUST account for inrush current, information on inrush for the lights being used will be available from the light manufacturer.


Dimmer Extension Loxone Dimensions


  • Mount the Extension on the DIN rail
  • Connect 24VDC power supply, but do not switch on until the whole installation is completed
    (we recommend looping power through the Miniserver)
  • Connect the inputs and outputs
  • Connect the Loxone Link
  • Note: If this is the last extension, terminate the Loxone Link with a 120Ω resistor (included with the Miniserver)
  • Turn on the power supply
  • After a few seconds, the left LED will flash green if the Extension is already configured, orange if not.
