Scaling Anolog Output 1769-OF4CI/A

3 posts in this topic

Good afternoon all,

  I have recently returned to programming, have forgotten a lot but slowly returning, I have a small programming question that I am hoping someone will be able to support.

I have a project that requires me to send a 4-20ma signal from an Allen Bradley  1769-OF4CI/A module to another manufacturers analog input card. 

I am looking for information on how to scale the card, for example how does the card know that a raw value of 10 is equal to 4ma and a raw value of 80 is equal to 20ma

This has got to be a very easy question, and I am sure I will kick myself once someone explains, but for some reason I cannot remember how to do this.

Thank You in advance
