You can't use it directly. All you can do - add some device, that would convert signals or choose another module, that supports 0-20. |

Hi, I have attached how I solved this problem when I used PT100 with a so called "Puck" that converts PT100s millivolts to 4-20mA. If you look at Network 43 where it starts with AIW16 you will se how it works. In earlier networks RTD modules is used so no linearization is needed. You really need a "Loop tester" to make sure you calibrate it right. I'm Swedish so there is some of my mothertounge in there if that is a problem drop me a mail.
