1734 IE8C 8 Channel Analog Input scaling

[jpratik92 1]

Hello all, 

I have a temperature sensor with a reading range of 10F to 212 . The input card I am using is an Allen Bradley 1734 IE8C 8 Channel Analog current input. The current input values are 4-20 mA. Currently I have my raw low at 4000 and raw high at 20000. Can anyone explain how do we go about selection of this values ? I found these values in the configuration tag of the input card properties. 

Thank You

I created a project with that card and it doesn't show a raw low and high. What I'm seeing is a Current Range, Digital Filter, and Low/High Engineering. Check the attachment to see that I have the correct card. If so, I'd set the following:

• Range to 4-20 mA
• Low Engineering to 10
• The High Engineering to 212.
