Can anyone point me to a schematic and parts list to build a simple, rugged circuit that can sense a 4-15 VAC source, without putting much drain on the source, and then provide a switch closure, which can handle 12 VDC to trigger a standard 15 amp car relay?
So when the 4-15 VAC is present the switch will close and energize the relay coil using a separate existing 12VDC supply
When 4-15 VAC is removed the switch will open
This will be used on a Motorcycle so it needs to be durable. It will also be in a possibly wet environment and perhaps hot too. I figure I can pot it in epoxy to improve longevity.
Thanks for any help you can provide. I am capable at soldering circuits, but not designing them or apparently finding them. I have found lots of other sample circuits but not this one. Perhaps I just don't know the proper terminology. :|
