KE20AS - Wind Sensor Electronic

Features:

·   Microprocessor based (can have new firmware loaded using on-board bootloader)

·   Two different wind different speed measurement methods and respective outputs

o Fast Wind Speed Measurement with digital output

§ Can (as an example)  be used for quick control of  Roller Shutter Systems

o Slow Wind Speed Measurement with analog output

§ Can (as an example)  be used to control regulations depending of a more precise measurement

·   3 status LED’s

o    Yellow       Wind Sensor (Anemometer) input pulse

o    Red            Fast Alarm Active

o    Green       Alive indicator

·   DIP-switch Programmable Alarm Threshold for the Fast Measurement Method Output

·   IHC ® compatible (Intelligent House Control by LK Denmark)
