Nowadays, with the wide automation of production processes and the introduction of automatic control systems, the requirements for the creation of contactless electric devices have substantially increased. The development of power semiconductor electronics allows the solution of complex technical problems aimed at improving the efficiency of electrical devices. The leading role in this direction is given to optoelectronic devices and thyristor devices, which provide contactless switching processes and galvanic isolation, and have improved transient and frequency characteristics The article deals with the creation of compact, reliable, highspeed optoelectronic contactless voltage relays with an extended service life, combining a sensitive system and a powerful actuator having a sinusoidal shape of the voltage curve at the load. Theoretical, experimental studies and the principle of operation of an optoelectronic contactless voltage relay with time delay are given.
