As you can see this is my first post. Maybe there is a 12 year-old on here who can help me.
I need a time delay to prevent a second relay from operating when the first one in the chain is monetarily triggered. I need about half to one second delay.
I have been given two simple time delay circuits for a 12v 1/2 to one second delay. I am trying to keep it simple as I'm not an electronics person. So I tried to avoid 555 timers.
So far I have built these but neither works. I started with the more complex one then went back to the more simple one. Nada.
I can only get the relay to activate by "bypassing the transistor. it is as if the transistor will not flow enough current to allow the relay to activate but will pass enough to hold it in.
Apart from the fact that neither work i don't know enough to be able to troubleshoot to find out why.
On the second simpler one I even tried to morph the two by using a separate 12v source to power the relay through the transistor. But still nothing. Coil power consumption is 0.36 to 0.45w
Are the designs flawed or am I using the wrong components
I have checked my construction but I see nothing obviously visually wrong.
