KNX Brightness Sensor

The KNX L brightness sensor measures the intensity of illumination and transfers the value to the KNX system. Six switching outputs with adjustable threshold values as well as additional AND and OR logic gates are available. The sensor system, the evaluation electronics and the electronics of the bus connection are mounted in a compact housing.

  • Brightness measurement: The current light intensity is measured by a sensor
  • 3 switching outputs for twilight (up to 1000 lux), 3 for daylight (1-99 klux), each with adjustable threshold values (Threshold values can be set by parameter or via communication objects)
  • 8 AND and 8 OR logic gates with each 4 inputs. Every switching incident as well as 8 logic inputs (in the form of communication objects) may be used as inputs for the logic gates. The output of each gate may optionally be configured as 1 bit or 2 x 8 bits
  • Configuration is made using the KNX software ETS
