KNX RW - KNX Rain/Wind Sensor 24 V DC
Product code:
70127
The rain/wind sensor KNX RW measures precipitation and wind speed and transfers the values to the KNX system. Four switching outputs with three 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.
Description
- Precipitation perception: The surface of the sensor is heated so that only drops and flakes are recognised as precipitation but not fog or dew. If it stops raining or snowing, the sensor dries quickly and the precipitation message ends
- Wind measurement: The wind strength measurement takes place electronically and thus moiselessly 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
- 4 switching outputs, 3 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
