御回路。 It is equipped with a synchronization signal generation circuit 2 that generates a signal synchronized with the AC power supply, a control element 1 that inputs the signal, and a relay 5 that opens and closes according to the output of the relay drive signal 6 of the control element 1, and generates pulses of the signal synchronized with the AC power supply. The width T and the time ToN from its rise to outputting the relay drive signal 6 are stored in the control element 1, and the pulse width T1 of the synchronization signal of the power source whose voltage has fluctuated is compared with the pulse width T, and the time difference is calculated. T-T 1
A relay control circuit characterized in that the time ToN until the relay drive signal 6 is outputted is changed in response to the output of the relay drive signal 6.
