Please read those terms and conditions carefully. Other then that I’m at a loss. It’s like having the store come to you! All logos and trademarks are properties of their respective companies.

First I would use different power supply than the AB for loop power. The N14 Analog Input module contains 4 analog input channels that are user selectable per channel for voltage or current to support a variety of monitoring and controlling applications.


Are you using it in mA mode? Shields should be tied to earth ground at one end only, not the PS return, also typically the PS return should be tied to ground as well, unless there is some reason you need it floating.

What is the measure PS output current? For the analog signal cabling, connect the shield ground only on one point, maybe near the analog input module. Visit our Post Archive.

We appreciate your interest in using our 1746-ni4i website! Get a scope or a scope meter, you may even be able to locate the noise with a AC voltmeter set on low range.


Is the problem apparent on all analog inputs or just a few?

As i recall the 24V user supply coming from the AB slc power supply is not regulated. Due to phasing difference between two different power sources that is one item could be on phase A and other on B. AB SLC analog inputs typically have at least 1, sometimes 2 bits of noise anyway. Our calculations indicate we have planty of margin 17466-no4i PS.
