Frauenfeld, Switzerland

Example:

A 10m long line has a resistance of approx. 1Ω. The sensor draws a current of 90mA. According to Ohm's law,
the following voltage drop occurs at RL1:

URL1 = RLine * ICC
URL1 = 1Ω * 90mA = 90mV

In this example, the U-Out is increased by 90mV.

Tip:

Many measuring inputs can, however, only be operated with 0…10V. Using a simple trick, 2...10V can,
according to Ohm's law, be generated from 4...20mA with a resistance of 500Ω (parallel switching of two RM
resistances of 1000Ω). That way the effect can be avoided.
