The MS multi sensor sends the current weather details, including brightness (from three points of the compass), wind, rain and frost, to the multifunction sensor relay MSR12-UC connected in series once per second. A standard telephone wire is sufficient as connecting lead: J-Y(ST)Y 2x2x0.8 or equivalent. 100m line length is permitted. Solid plastic housing, l x w x h = 118x96x77mm. Protection degree IP44. Temperature at mounting location -30°C to +50°C. A power supply unit SNT12-230V/24V DC is required for the power supply, including heating of the rain sensor. This is only 1 module = 18mm wide and it also it supplies the multifunction sensor relay MSR12-UC. Several MSR12-UC can be connected to a multisensor MS, e.g. for evaluating up to three directions with the light sensor of the MS.
