KNX RW sl

Precipitation/wind sensor for KNX

The Precipitation and Wind Sensor KNX RW sl for the KNX building bus system measures wind speed and detects precipitation. The wind value can be used for the control of limit dependent switching outputs. States can be linked via AND logic gates and OR logic gates. Multi-function modules change input data as required by means of calculations, querying a condition, or converting the data point type.
The compact housing of the KNX RW sl accommodates the sensors, evaluation circuits and bus-coupling electronics.


  • KNX RW sl (70162) KNX RW sl (70162)
  • Wind measurement: The wind strength is measured electronically and thus noiselessly and reliably, even during hail, snow and sub-zero temperatures. Even turbulent air and rising winds in the vicinity of the device are recorded
  • Precipitation detection: The sensor surface is heated, so that only drops and flakes are recognised as precipitation, but not mist or dew. When the rain or snow stops, the sensor is soon dry again and the precipitation warning ends
  • Switching outputs for all measured and computed values. Threshold values can be adjusted per parameter or via communication objects
  • 8 AND and 8 OR logic gates, each with 4 inputs. All switching events as well as 16 logic inputs (in the form of communications objects) can be used as inputs for the logic gates. The output of each gate can be configured optionally as 1-bit or 2 x 8-bit
  • 8 multi-function modules (computers) for changing the input data by calculations, by querying a condition or by converting the data point type Configuration is made using the KNX software ETS.
