The weather data multisensor WMS transmits the currently recorded weather data once per second: brightness from three directions 0-99,000 Lux, wind speed 0-35 m/s, rain, and temperature -40-80 °C to the connected MSR12-UC, FWG14MS, or FWS61-24V DC. A standard telephone cable J-YSTY 2x2x0.8 or equivalent is sufficient as the connection line. The permissible cable length is 100 m. It features a compact plastic housing with dimensions L x W x H of 118 x 96 x 77 mm, protection class IP44, and an operating temperature range of -30 °C to 50 °C. A power supply unit WNT15-24VDC24W or WNT61-24VDC10W is required for powering the device, including heating for the rain sensor. To evaluate a WMS multiple times, up to 64 evaluation units MSR12-UC, FWG14MS, or FWS61-24V DC can be connected to the weather data multisensor.
