Timer Relay Circuit Diagram. Delay timer with relay i am looking to build a circuit that would control an output relay. A time delay relay consists of a normal electromechanical relay along with a control circuit to control the relay operation and timing.
The following circuit was requested by fastshack3. The time delay of the circuit can be increase or decrease by increasing or decreasing the value of 470uf capacitor. A time delay relay consists of a normal electromechanical relay along with a control circuit to control the relay operation and timing.
A time delay relay consists of a normal electromechanical relay along with a control circuit to control the relay operation and timing.
The circuit is able to trigger the relay from few seconds to few minutes after pressing the push switch s1. To prevent 555 timer from flyback current in the relay use a diode before the relay. 2 3 connecting 10amp negative sink output timer 3. Some 555 versions may get damaged because of this.
