A pulse signal 3 synchronized with the AC power supply includes a synchronization signal generation circuit 2 that generates a signal synchronized with the AC power supply, a control element 1 into which the signal is input, and a relay 5 that opens and closes according to the relay drive signal 6 output of the control element 1. The control element 1 stores the time T from the rising edge of the pulse signal to the falling edge of the next pulse signal and the time T 0 N from the rising edge to outputting the relay drive signal 6,
Compare the time T1 from the rise of the pulse signal 3A to the fall of the next pulse signal 3A synchronized with the voltage fluctuated power supply with the time T , and calculate the time difference T-T.
1. A relay control circuit characterized in that a time T 0 N until outputting a relay drive signal 6 is changed in response to a relay drive signal 6.
