Timing AC power supply circuit diagram that supplies power for 0-1 hour

As shown in the figure is a timed AC power supply circuit diagram that supplies power for 0 to 1 hour. The timer within 1 hour is composed of 555. J is an IRC MR312C relay with a coil impedance of 212Ω, or a 12V relay with a current less than 200mA. The parameters in the picture, the delay time is 3~58 minutes. If you want to obtain other timing ranges, you can change the values ​​of R2 and C1. Looking clockwise from the top of the NE555R, the pin order is 8, 3, 4, 2, 1, 7 and 6.
