Hi all. I have a very small project, with a very tight budget in which I'll be adding some AB flex I/O. Per the 1794 manuals, analog/RTD modules should be fed with a separate power supply than the digital modules. Normally, I would design this way, but in an effort to budget the solution, has anyone skimped and used a single power supply for both module types without experiencing noise issues? The temperatures I'm reading are not super critical, which is why I'm considering this as a cost cutting measure. All feedback is appreciated.
