Rain sensor. The rain sensor is used to record and evaluate precipitation and is intended for external mounting. A sensor evaluates the conductivity of the rainwater. The heating is controlled by a microprocessor which supplies an output signal of 0 V or 10 V. The end of the rainfall can be recorded almost immediately with the help of an in-built heater. The heater requires an additional voltage of 24 V AC or DC. For external installation and connection to the weather station REG-K/4-gang or the analogue input REG-K/4-gang. These two devices provide the supply voltage necessary to operate the sensor. Output: 0 V dry, 10 V rain. External power supply: Voltage: 24 V DC (15-30 V DC). Power consumption: approx. 10 mA (without heating). Heating: 24 V DC/AC max. 4.5 W. General specifications: Type of protection: IP 65. Incoming cable: 3 m, UYY 5 x 0.25 mm². Fixing method: Mounting bracket. Mounting position: approx. 45°. Contents: With holder for installing the sensor on walls and masts.
