Timer Relay Diagram. The circuit is able to trigger the relay from few seconds to few minutes after pressing the push switch s1. The figure below shows a very simple and useful project schematic of a time delay relay circuit using a 555 timer ic.
Our channel provide the best electrical video tutorials which is about electrical wiring home wiring transmission line hv mv lv motor control sequence. The figure below shows a very simple and useful project schematic of a time delay relay circuit using a 555 timer ic. The timer function 1 is on delay it allows to supply power after a period of time t.
The circuit is quite simple and using only few external parts with the ic.
It shows the components of the circuit as simplified shapes and also the power as well as signal connections in between the gadgets. When the trigger is applied the time delay t1 begins. At the end of the time delay t2 the output is de energized and the time delay relay is. The following is a timing diagram of this relay contact s operation.
