Good morning all.
I have never seen this done but I want to ask if it is possible. On an AB 1766-L32BWA, can you have some of the inputs wired as sinking and some wired as sourcing, depending on whether you connect the 24 VDC or the 0 VDC to the "DC COM". See attached screenshot of the manual.
Example: So if I connected the 24 VDC to the DC COM 0, 1, & 2, inputs 0 through 11 would be sourcing and I connect the 0 VDC to DC COM 3, inputs 12 through 19 would be sinking inputs? I am not sure if all of the DC COMs are electrically isolated from each other.
It seems like this can be done, and there is a small blurb about it in the manual but I wanted to make sure I read it correctly.
