FEATURES:
1.Whether there is rain or snow measurement, response time ≤ 0.5S.
2.Unique AC measurement technology prevents oxidation of the induction disk and ensures long-term sensitivity.
3.IP68 protection grade design, can work outdoors for a long time.
4.Multiple transmission modes are available, providing 485 mode upload or switch output for easy centralized monitoring.
5.Optional automatic heating function, can be used for snow detection, in the case of long-term below 0 degrees and high humidity environment, to prevent icing condensation.
6.When heating, the temperature is strictly controlled within 40 °C (default) to prevent dry oxidation and prolong the service life.
7.The sensitivity of the sensor is adjustable and the use is more flexible.
8.You can set alarm and reset delay to avoid frequent alarms on site.
Electrical Wiring
The voltage power input can be 10~30V. When wiring the 485 signal line, note that the A/B lines cannot be connected in reverse, and the addresses between multiple devices on the bus cannot conflict. Switching type devices are equipped with one relay output as standard, and two outgoing lines (green and white) are normally open contacts.
