Time Delay Relay
|Home > Circuits > Other > Time Delay Relay|
|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.|

|i want a timer ckt which works 60 sec. in 2 hours and this is repeately. this ckt used in agriculture purpose, out the water from water tank only for 60 sec. and off.|
|Thanks Aaron for the original circuit and thanks to WillyAG for the little mod needed for my purposes.|
|If I want to use a 5v relay which parts of the circuit is to be changed. can the power supply can be reduced to 9v while using a relay of 5v. Expecting that I got an answer|
|I need someone to make me a very small circuit that is on for 10seconds and off for 60 seconds and then it repeats over and over using a 3v cell battery|
|This was EXACTLY what I needed to complete my project. Thank you so much for taking the time to post it.|
|i already get the cicuit in 12 volt,but my problem is i would like to increase my voltage into 24v so also increases my relay into 224v but wont work or oerate,pls help what to add components or change?i want 24v dc to run my motor|
|If I use 9V as my input power supply,,,, do I have to change anything else??? And,,, I am not going out to a relay,,, I am going directly to an E-Match,,, to trigger an ejection charge in a model rocket.... But I do want all the power I can get,,, to make sure the charge ignites.. Thanks...|
|I'm looking to adjust the time of the delay for 1week. How do I calculate the change required to the capacitor? i want to know more about delay...|
|Thanks for the circuit diagram. Last some days I was searching the same, which I want to used. I hope it will help to me.|
|Aaron, I have know you through the RX-7 world for years. But when I go to search for a time delay relay to build one, your site comes up second on Google. Mind blowing. Water level low>water valve opened (heating system)|
