Hi all,

I need some advice on how to read a temperature "on the cheap"

I have a PLC, it allows for 0-10volt input "analogue", I know than you can some way have a RTD, NTC or somthing similar, maybe in series with a fixed resistor.
I have a 24volt DC power supply
I am looking for a control temp of 120C
( I know that you can but a converter, but are expensive in this application)

cheers
