A 4 20 mA signal is sent to a 12-bit Modicon PLC input card, which in turn, sends this to a SCADA. If the signal happens to be 14.25 mA, calculate:
What percentage of 0 - 100% will this represent?
What value would this have on the PLC ( it is a 12-bit card)?
If we are displaying a value of 0 - 350 kPa, what value would be displayed on the SCADA screen?
