| A time delay relay is a relay that stays on for a certain amount of time once activated. This time delay relay is made up of a simple adjustable timer circuit which controls the actual relay. The time is adjustable from 0 to about 20 seconds with the parts specified. The current capacity of the circuit is only limited by what kind of relay you decide to use. |

| Hi All, How can i build a timer relay that will run for a prox 8min and then switch itself off. Then switch itself on once a button is pushed running the 8min timer again? This is a solar powered project that charges a batt and the batt will run a screen. Outdoors. Cheers in advance.. | ||
| hi sir, i'm an electronics student, my cousin and i are planning to make an automobile's horn with time delay, does this circuit work with it? thanks. | ||
| Hi I build up this circuit and done a PCB design of it too and works me perfectly. I want to know a brief description of each component what is doing. My timer operates between 0 to 50seconds beacuse I changed the value of R1 and C1. I wish to hear from you thankyou. Regards Nicolai | ||
| Dear Sir, Is there any variations occurs in turn time delay, when we extend weightiest slowly i.e. form 4000 to 16000 ? Means when we measure turn on time delay with the help of oscilloscope, Is waveform diagram same for all model or they differ in their AC-DC slpoes? | ||
| Hi There, I live in a circa 1989 house that has a time-delay relay box. I'm not really sure why it's there, what the purpose is and if it's in good working order or not. I am not electrically inclined, but do know that it makes an almost continuous buzzing noise that isn't very loud, but definitely noticeable. Any hints you might be able to offer me? Thanks in advance! | ||
| The time you can count with this formula: T(s) = 1.1 * R1 * C1 | ||
| Hi, What NPN transistor is needed in order to allow this circuit to be activated by the rain detector circuit on this website? | ||
| Am looking for a time delay relay that is energized by a small DC input (12V) and changes its normal state (NO) to the other state after the preset time is reached but remains at its normal state if a second DC input is fed before preset time is reached at the same time reseting the time to zero en counter stops. | ||
| Dear Sir Where can I add a resistance to chose the time between 0 to 9 second ? What do I need to change to make the circuit work with 24V DC? May I know the line , in and out and what the current value. To be connected to 24V pump so the pump will work for the range 0 -9 second and stop Thanks Samer | ||
| I need a relay timer to switch off after 6 hours. Basically I want to add in my battery charger. | ||
