The A70H-RS Rain and Snow sensor provides qualitative detection of rain or snow. The unit automatically heats to melt snow on the sensing surface. It is designed to provide control of automated windows, wipers, and snow melting systems. The ring conductor senses rain or snow on the surface and generates an output switch signal. Standard configuration is a normally open (NO) relay. Other outputs are optional – contact factory for information.
| Relay (NO): If there is no rain or snow on the sensor surface, the relay is open. If there is rain or snow the relay is closed. |
