RUT955 Current Measurement with Analog Input

If you want to measure the current with RUT955 you need to connect a resistor as shown in the picture below. Note that voltage on pin 9 must never exceed 24V.

Configure resistor value and analog input name in the router's WebUI (see here).

This is commonly used with 4-20mA standard sensors. If your sensor has linear characteristics, you can also configure a sensor slope and offset to directly get measured values. To have correct value in WebUI, the resistor needs to be 1200ohm, if 24V power supply is being used. If different voltage is used, an Ohm's law formula can be used to calculate the correct value (U/I=R).
