FIELD: electrical engineering. SUBSTANCE: time relay has diode bridge which A. C. diagonal is connected via actuating element to terminals for linking of A. C. network, series RC circuit to which center input of threshold element is coupled, filter capacitor which first output is linked to first lead of D. C. diagonal of diode bridge, thyristor which anode is connected to second lead of diagonal of D. c. diode bridge, first resistor and diode. Time relay is supplemented with series circuit composed of second resistor and stabilizer diode, variable resistor, two resistors and two diodes connected in series in certain way. EFFECT: enhanced operational reliability. 2 dwg
