KNX LW 20...30 V DC
Brightness/Wind Sensor
Brightness/Wind Sensor for KNX (sun, light and wind speed)
The brightness and wind Sensor KNX LW measures the intensity of illumination and wind speed and transfers the values to the KNX system. Nine 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
- Wind measurement: The wind strength measurement takes place electronically and thus noiseless and reliable even in case of 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, the maximum measurement value of 35 m/s is output as a fault message. All wind alarms with a limit value below 35 m/s become active as a result
- 9 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
