i would like to cal the fuse rating for the battery monitoring circuit.
i have attached the image.
Vinput=56V battery input and my desired vout to the plc input should be 9V.
i have chosen the resistances to be 5.6K and 1K ohm.
So by calculation i get the max current in the plc to be 6.6mAmps.
Now how would i determine the fuse rating. for eg if i take a fuse rating of 0.5A then would the plc be protected when the battery voltage is 56V.
