I/O for CSS PUMP

[spongebob17]

Hello,

Just graduated as an electrical engineer.

Anyway, I am evaluating I/O's for a CIP System. On one of their CSS pumps, it said 2in/2out, with Analog 1in/1out. What would these I/O's be? The analog I/O might be for a VFD and the other 2in/2out I'm guessing is running/fault at the input side and reset/? at the output. I'm not sure...can anyone explaing why there are 2in/2out?

Thanks!

Is this related to a valve?

Yes...there are several valves that feeds this pump. I am not sure what they are.

I am still unsure of what your valve question is. Maybe try again?
