General Technical Chat / Relay trigger when voltage above 13v
« Last post by bigjoncoop on Today at 12:07:41 am »Trying to create a simple circuit that will trigger a relay only when the monitored voltage is above 13v.
(the output voltage of the circuit is not important. Just needs to be 0v when the monitored voltage is below 13v)
I was able to find a couple of threads on this, but there was no clear answer in the end...
I was originally thinking of using a LM386 and a TL431 as a voltage reference since I have alot of these components. But was unable to find a detailed schematic on how to do so...
Specs:
Monitored Voltage Range: 12v - 14.6v
Trigger Voltage: ≥13v
Output voltage to control relay: Not Important
