Technical support / Form of Analog Input

I have a windmill giving AC voltage out from 0 to 130 Volts
I want an input reflecting RPM or Voltage. Do I need to convert to DC if I use 0-20 mA or 0-10 V.
What load in voltage can the PLC take on the Pulse measurement input? Could i use some kind of diode that will work on low and high Voltage and still not be burned or burn the PLC
Programming will be controlling load on the windmill depending on the windspeed.
