Abstract

Dwustanowy układ wejściowy o zmiennej oporności z izolacją galwaniczną zawierający mostek prostowniczy, źródło prądowe, diodę Zenera, transoptor przełączający, transoptor wysokonapięciowy, dzielnik oporowy złożony z opornika wejściowego i obciążającego, przerzutnik Schmitta, układ całkujący i układ polaryzacji posiada na wejściu układu dwustanowego (WE) za opornikiem wejściowym (R1) i mostkiem prostowniczym (M) włączone kolejno szeregowo źródło prądowe (ŹP), katoda diody Zenera (DZ), której anoda połączona jest z anodą diody świecącej transoptora przełączającego (TP), której katoda podłączona jest z minusem mostka prostowniczego (M), a w węzeł między źródło prądowe (ŹP) i diodę Zenera (DZ) włączony jest jednym wyprowadzeniem opornik bocznikujący (R6), którego drugie wyprowadzenie podłączone jest do zacisku ujemnego mostka prostowniczego (M).A two-state variable resistance input circuit with galvanic isolation containing a bridge rectifier, a current source, a Zener diode, a switching optocoupler, a high-voltage optocoupler, a resistance divider consisting of an input and a load resistor, a Schmitt trigger, an integrator and a bias circuit has at the input of the two-state circuit (WE) behind the input resistor (R1) and the bridge rectifier (M) a current source (ŹP) connected in series, the cathode of a Zener diode (DZ), the anode of which is connected to the anode of the light-emitting diode of the switching optocoupler (TP), the cathode of which is connected to the minus of the rectifier bridge (M), and a shunt resistor (R6) is connected via one terminal in the node between the current source (ŹP) and the Zener diode (DZ), the other terminal of which is connected to the negative terminal of the bridge rectifier (M).
