Need a circuit design that can do the following:
Upon detecting 120 vac on/off/on (sequence input) during a 10 second input period, then power relay coil on (relay coil voltage and contacts to be determined.) Circuit should ignore electrical noise and other power on/off pulses outside the 10 second window. Removal of mains power to the circuit resets relay to un-energized state. In summary, any time the circuit "sees" mains power on/off/on during a 10 second window, then power relay on and maintain power to relay coil until mains power is off.
