Suntracer KNX-GPS 20...32 V DC

Weather Station, GPS Receiver, 6 shadings

The Weather Station Suntracer KNX-GPS measures temperature, wind speed and brightness. It recognises precipitation and receives the GPS signal for time and location. In addition, using location coordinates and the time, it calculates the exact position of the sun (azimuth and elevation).
All values can be used for the control of threshold value-dependent switching outputs.
States can be linked via AND logic gates and OR logic gates. The compact housing of the Suntracer KNX-GPS accommodates the sensors, evaluation circuits and bus-coupling electronics.

  • Brightness and position of the sun: The current light intensity is measured by a sensor. In addition the Suntracer KNX-GPS calculates the position of the sun (azimuth and elevation) using time and location
  • Shade control for up to 6 facades with slat and shadow edge tracking
  • 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
  • Wind sensor monitoring: If the wind measurement value changes by less than ± 0.5 m/s within 48 hours, a fault can be output. The wind measured value is output with the maximum measured value of 35 m/s and all wind threshold values below this value become active
  • Precipitation recognition: 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
  • Temperature measurement
  • Weekly and calendar time switch: The weather station receives the time and date from the integrated GPS receiver. The weekly time switch switches up to 4 different periods per day. With the calendar time switch up to 3 additional time periods can be defined, in which up to 2 On/Off switches take place. The switching outputs can be used as communications objects. The switch times are set via parameters
  • Threshold values for all measured and calculated values can be set via parameters or communications objects
  • 8 AND and 8 OR logic gates with 4 for each input. 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 optionally configured as 1-bit or 2 x 8-bit
  • Configuration is made using the KNX software ETS
