Further information for Schalk GSR209 limit switch 230 VAC
The limit switches GSR 2 and GSF 2 are versatile and yet uncomplicated and easy to use. The GSR 2 is used in conjunction with the SR 1 sensor for rain detection. The connected sensor is supplied directly by the limit switch with a potential-free extra-low voltage (PELV). The use of an additional power supply is therefore not necessary.
