benoitbaillargeon Posted September 4, 2013 Report Share Posted September 4, 2013 HI, I am using the JZ10-11-R16 and trying to read a 4-20mA signal on the AN0. Thing is I can'T go higher than 1024 when I read the input even if I am around 9.5mA. I have configured the AN0 for 4-20mA and to be put into MI0. Any Idea?

benoitbaillargeon Posted September 4, 2013 Author Report Share Posted September 4, 2013 I Believe that, even if it is labelled JZ10-11-R16, it might be a JZ10-11-R16/V. Because if I check the impedance between the 0v and my AN0 input, i get 155ohm which is weird considering it is 4-20mA, therefore suppose to be 5Mohm.

Alexander Posted September 4, 2013 Report Share Posted September 4, 2013 The JZ10-11-R16 has a 10-bit analog input resolution, so the expected raw value for a 4-20mA signal will only be between 204-1023. Have you wired the Jazz hardware according to the 2,3, or 4 wire configuration within the installation guide? Link to comment Share on other sites More sharing options...
benoitbaillargeon Posted September 5, 2013 Author Report Share Posted September 5, 2013 We found the problem. It was indeed a JZ10-11-R16/V not a JZ10-11-R16 even if it was labelled like a non V. Problem Solved! Link to comment Share on other sites More sharing options...
Alexander Posted September 5, 2013 Report Share Posted September 5, 2013 I do not believe we offer separate models for a R16 or R16/V as they should be the same. To verify what you are describing would you be able to email support@unitronics.com with details including a serial number? Link to comment Share on other sites More sharing options...
Gabriel Franco Posted September 5, 2013 Report Share Posted September 5, 2013 R16, R16-V, R16L, all of them appear in documentation files and clearly defines analog input differences, however I only see R16 in webpage. Suggestion for web administrators: Update web page information, as well as comparison tables. I use to get info from there to define which device fits my requirements Link to comment Share on other sites More sharing options...
