if voltage is 5v ,the 24v supply is ok
else it is shorted to earth. I said:
That is not a correct conclusion!
There could be a number of other reasons why the voltage would drop - the most obvious being a failure of the incoming mains supply. You need further evidence to be able to state that it is specifically a short to earth that has caused the supply to drop! Rustu Kaya said:
But, What if supposingly 24VDC drops to 20V? According to your calculation. 20-18=2VDC and your controller will interpret it SHORT. If you accept it as a short, keep going.

i suugest u to use a simple voltage divider by two resistor Apart from the SMS nonsense, your suggestion doesn't even address the flaw in the OP's "solution" Why do you suggest this? How will it help? |
