Hi All,
I don't have a ton of experience with PLCs yet, so I appreciate any feedback I can get. What I am doing is using an Omega FMA1816A mass flow sensor reading scfh units. Let's say our spec is 2scfh @70psi for leak checking purposes. Assume anything greater than that value is a fail condition = bad part. The omega meter has an option for 0-5VDC or 4-20mA output signal.
I've done some reading on them, and I cannot determine which is the better path to go? As close as we are to the control pane - I can't see voltage drop being a huge issue. At the same time, which O/p type you get from the omega meter determines which kind of analog card for the PLC you need, correct?
For reference we will most likely be going with AB Compact Logix PLC; we have them in use everywhere in the plant.
Thanks!
