We’re in the middle of choosing new PLC’s for monitoring levels, temperatures and pressures in our storagetanks, all in all something like 24 analog inputs.
I’ve talked with our supplier of PLC’s, but they didnt know a lot about the Allen Bradley product line, which i’d chosen since it seems ignition supports them more than other brands.
My problem is that all these different plc’s seem to favor digital inputs, and what i really need is analog.
My question is:
Is there a cost effective solution to get:
24 analog IO ports,
Or should i try to limit the amount of inputs?
