Analog Input

[benoitbaillargeon]

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?

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.

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?

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!

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?

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
