Need help picking 12v timer!!

[Storyteller12]

I need a 12v timer that cuts on when 12v applied (when door is opened) and cuts off after 2 minutes even if he door stays open with the 12v trigger. And resets when door is closed.

The ones I see tend to start the timer when powered down. (Momentary switch)

Thanks in advance

Re: Need help picking 12v timer!!

Ok. Received the items and they works pretty much as described. However if I shut the door the lights stay on until timer runs out. I need them to turn off when when the door shuts also.

I cannot find a setting to change that. Any ideas?

I need it to work pretty much like a car door.

If I open the door light turns on and if I close it light turns off. It if I open the door and leave it open the light will cut off after set period of time so it won’t kill the battery.

I had it working like the way I wanted without the timer and just a relay. Seems this timer messes things up.

Thanks in advance.

Re: Need help picking 12v timer!!

From what I read in the description you have to program the on time and off time
But I could be wrong but should give you an option that is turn on for a certain amount of time and then shut off

There doesn’t seem to be a way to have the timer relay turn off when I close the door. So I used another relay and hook up the timer output to the new relay input and and it works that way.

Sucks I had to use an additional relay but it works the way I wanted which is most important.

The reason why you can not find something already made is because you parameters are not what is commonly used so you have to make your own you might have been able to use a machine safety relay but would have to been one that you program and it might have work for you but I did not mention it before because if you are not used to working with them especially the programmable ones it can be a real learning experience

I have used them and programmed them before and sometimes the instructions are not very clear how to set it up for what you are trying to do with the setup and how you need the setup for it to work correctly

Can you please explain exactly how you want this to work

Is it that you want it to time while the door is open and if was not closed in a certain amount of time then it turns off or if you closed the door it would turn off am I correct with what I have decried here or is it something else that you are trying to accomplish if this is the case please explain further

I can tell you that the car lights in my car do not work exactly like that how mine works is that when you open the door and close it the timer times out and then shuts off what you are doing is if the door closes you want the timer to be done and turn off
