Hi Sean - Glad that you find them helpful. Thank you,

Thank you for explaining that, very helpful. I am currently working on a project that is using the 1756-IF8 module in current mode(4-20mA). Can you please go over the wiring in more detail? The manual shows a bunch of different jumpers.

[@abplctestbench759]

HI:
If you are using all channels in the single ended mA mode then all of the right side odd numbered terminals 1 thru 17 are jumpered together.
Terminals 9 & 10 are common to each other (jumpered inside the card).
See the manual page 11.
Hope that clears it up for you.

@@abplctestbench759 Ok, thank you! Also, what is the big difference between single-ended and differential? Is single-ended the most common way to wire a 4-20mA signal?

@@abplctestbench759 I will be using Differential wiring.

@@kilowatts76 Hi: Differential will cut down the number of available inputs but will make the ones you are using higher accuracy. There is additional programming and configuration to do compared to single ended.
In the end it all depends on the situation you are using them for and what you want for your system.
All the different ways are correct if they work they way you want them to for your process.
