Hi all,

As stated in the title, I have a 1756-IF16 module that was previously only running 4-20mA current inputs. I am now adding in 3 0-10V voltage inputs, and have configured them as such in Rslogix 5000 v19.11. We are simulating a 0-10V input using a process meter which is working fine, but once we inject 0-10V into the card it only reads 2.5V max (we also had a meter on the terminal we were injecting and it was reading 0-2.5V when the channel was connected & 0-10V when it wasn't).

Does anyone have a solution for this? All the returns are currently bridged with a jumper but from what I've read that is required regardless of if we use voltage or current.
