Length of cable and supply voltage for current output
For sensors with current output, the required supply voltage increases by the voltage
dip on the connected cable. The most significant voltage dip on the cable occurs when
the maximum current of 20 mA is flowing, caused by the resistance of the cable (R
L
).
The partial resistances of the go and return line must also be taken into account.
