BF30: Rain Sensor mod. BFSP02
This device is designed to detect the rainfall by means of an external probe containing internal heating elements and connected to the control unit through four wires. The output is fitted with an exchange contact without voltage, which is activated by rainfall. The control unit, mounted in a modular container, allows for the adjustment of delay time upon output activation, output deactivation and adjustment of the level of sensitivity of the external probe. The front panel is fitted with three LEDs that indicate the presence of power supply, the output status and the presence of rain. The external probe comes with a stainless steel fastening stirrup for installation of the probe in either a vertical or horizontal position.
