Separators SGS-12 series create galvanic isolation between input and output circuits. Separator doesn’t need any power supply. 0/4-20 mA current output signal can also be processed into voltage 0/2-10V signal with standard 500Ω load resistance. Then for class 0,5% it is advised to use voltage input R ≥ 100 kΩ. Quality of isolation depends on breakdown voltage and also capacity between separated circuits.
Input signal direct current 0 ÷ 30 mA (max. current
50 mA, max. input voltage:30V), input voltage divider:1,9V + 20mA x Rload
Output signal current
direct current I =I ; load resistance:0-1000 Ω out in voltage:with external resistor on output; terminals for 0/4÷20 mA input:50 Ω → 0/0.2 ÷ 1V 250 Ω → 0/2 ÷ 5V 500 Ω → 0/2 ÷ 10V
Accuracy ±0.05% - 0.05% (Rload / 100Ω)
