The weather data multi-sensor WMS sends the currently recorded weather data brightness from three directions (0.99,000 lux), wind (0.35 m/s), rain and temperature (-40.+80°C) to the downstream MSR12-UC, FWG14MS or FWS61-24V DC once per second. A standard telephone cable JY(ST)Y 2x2x0.8 or equivalent is sufficient as a connection cable. Permissible cable length 100m. Compact plastic housing, lxwxh = 118x96x77mm, protection class IP44, ambient temperature -30°C to +50°C. A power supply unit WNT15-24VDC/24W or WNT61-24VDC/10W is required for the power supply including heating of the rain sensor (Chapter 17). In order 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 multi-sensor.
