KNX Wind Sensors

The Wind Sensor KNX W electronically measures the wind speed and transfers the value to the KNX system. Three 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.


N° 70122 KNX W 230 V AC
N° 70123 KNX W 12...40 V DC / 12...28 V AC

  • Wind measurement: The wind strength measurement takes place electronically and thus noiselessly and reliably, even during hail, snow and sub-zero temperatures. Even turbulent air and anabatic winds in the vicinity of the weather station are recorded
  • 3 switching outputs 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
