Diagram 555 Timer Power On Delay Circuit. The most important component of this circuit is a 555 timer ic. Working of time delay circuit.
When appliance or load is turn on then after a fix time duration automatic switch off. Timer circuit for delay switch off. When the push switch is pressed the 555 timer will be triggered for a preset time period and after that time period is completed the 12v relay and an led will be activated and any electronic device or appliance connected with the relay will become switch on.
This is one of the most versatile and commonly used ics.
We connect a 100μf capacitor to the positive voltage supply and then to pin 2. This is one of the most versatile and commonly used ics. The use of time delay switching and the effects. Here a circuit diagram of delay power off timer circuit for off time delay switch off delay timer circuit diagram.
