Using long time timing integrated circuit RS6445C to form intermittent oscillator

Shown is a intermittent oscillator using a long-time timing integrated circuit RS6445C . WI and W2 divisions are used to adjust working hours and shutdown times, both of which can be continuously adjusted within 0.5-24 hours. In the figure, two RS6445Cs can be used to make two independent timers. The timing time of each timer is determined by the preset levels of R and C and the ④ and ⑤ pins. The timing time can be adjusted by the resistor and capacitor installed at the ① pin .
