Have been looking around for a way to convert a sinewave (minimum pk to pk of 80mV) to a square wave of 0-24V (realistically need above 18V to definitely register a high) for PLC input, maximum input however can be greater than 12V pk to pk. Specs for the anemometer are at

Was thinking of using LM393 comparator but don't know if it will trigger at such low signal strength. Frequency will be between 1Hz to 200Hz and then how to protect it with the higher peak to peak voltages.
I would run the circuit from a +24V DC supply.
Most circuits show it using the inverting input. Why is this? I would prefer to use the non-inverting.
Many thanks
