Without auxiliary power

Isolators provide full galvanic separation of the input circuit from the output circuit. Isolators in the section "without auxiliary power," do not use any auxiliary power source.

  • SGS-12
    Isolators SGS-12 series create galvanic isolation between input and output circuits. Isolator doesn’t need any power supply. 0/4-20 mA current output signal can also be processed into...

    Accuracy ±0.05% - 0.05% (Rload / 100Ω)
    Power supply directly from current loop
    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
