Abstract: A method and an apparatus measure an actual responsive time for a relay and control the open/close timing for the relay. The apparatus comprises a microprocessor and two conversion units. One conversion unit processes an input sinusoidal signal for the microprocessor and the microprocessor sends a control signal to energize or de-energize a coil of the relay at an arbitrary time point. Another conversion unit senses a waveform change after the switch of the relay and sends a state signal to the microprocessor. Therefore, the microprocessor can obtain an actual responsive time of the relay by the difference between the control signal and the state signal. The microprocessor will apply next control signal with a time lead of the responsive time before next zero-crossing point to achieve zero-crossing switch for the relay.
