Power frequency 0-5 minutes delay circuit is shown as the above picture.This circuit uses double grid mosfet RCA40841 to constitute controlled silicon trigger circuit and the R value determines the delay time.When R is 60MΩ(LRC type CGH type resistor) and the relay time is 5 minutes and bidirectional controlled silicon can drive large current resistance loading or electrical resistance AC loading.And the error is within 10% if it is in -25~+60℃.
