In the article based on the results of the analysis of the existing opto-thyristor resistive circuits, a new scheme of the optoelectronic contactless voltage relay has been developed and its application in the power supply system has been considered. The possibility of controlling the operating modes of various installations amplifying electrical signals using optothyristors is presented and the ways of their inclusion in electrical circuits are presented. The optoelectronic contactless voltage relays were tested in laboratory conditions to obtain an input-output characteristic and a form of capacitance voltage. Based on the improvement of the proposed circuit, a circuit of an optoelectronic contactless voltage relay is developed and provide a high degree of reliability. The simulation of the proposed voltage relay circuits is performed using the MATLAB R2014a program, the results of which show that changes in the shape of the output voltage curve are close to a sinusoid and coincide with the results obtained analytically. As a result the obtained conditions of use make it possible to obtain a voltage with a sinusoidal shape on the load and achieve a relay return coefficient close to unity.
