Alan, for PLC analog input devices, normally they are either 0-5VDC, 0-10VDC or 4-20mA.  You can by analog input modules for the PLC in any of these flavors.  Most popular are 0-5VDC and 4-20mA.

What is the best sensor input to get for a PLC or doesn't it matter.
The pressure sensors I am coming across have either 0-5V output
or some amp range.
Wish I had heard Jon's talk at the last convention. Was that recorded?
Thanks
Alan
