PCE Instruments Rain detector module 1 pc(s) PCE-FST-100-2007-RSS Cable length: 90 cm (L x W x H) 75 x 90 x 37 mm Incl.

The rain and snow sensor detects rainfall and is used to monitor the weather conditions in environmental stations, irrigation control or industrial installations. The rain and snow sensor enables a fast and safe reaction to rain or snow. The sensor detects the presence of precipitation through conductivity and condensation properties and provides the information digitally via RS-485 Modbus RTU as well as via a potential-free relay output, over which external devices or controls can be switched directly.

The integrated relay output is designed as a normally open contact and offers a galvanic separation between the sensor voltage and the switched circuit. This allows the implementation of low voltage as well as mains voltage applications. The maximum switching power of the relay is 250 VAC at 1 A or 30 VDC at 1 A, making it suitable for direct control of controls, actuators or relays.

The supply voltage of the rain and snow sensor is 24 … 30 V DC. The compact, corrosion resistant housing is IP65 protected and intended for surface mounting. The automatic heating function activates at lower temperatures from an ambient temperature of 0 °C and warms up the sensor surface to about 40 °C, in order to prevent ice from forming. Thus the rain and snow sensor works reliably even during frost It is mainly used by weather stations, environmental researchers, irrigation systems and industrial applications where precipitation is to be reliably detected and automated responses are implemented.
