To convert a 4-20mA signal to a 0-10V signal, you can use a current-to-voltage (I/V) converter circuit. The conversion is performed by a simple resistive divider network, where the 4-20mA current is passed through a precision resistor and the voltage across it is proportional to the current. The voltage is then amplified to the desired range of 0-10V and fed to an analog input of a control system or data acquisition device.
Here's a simple circuit for converting 4-20mA to 0-10V:
Connect a precision resistor in series with the 4-20mA current loop, with a value of typically 250Ω.
Connect the voltage across the resistor to a non-inverting amplifier, with a gain of 2.5 to amplify the voltage to 0-10V.
The output of the amplifier is the converted 0-10V signal.
Note: The precision of the conversion will depend on the accuracy of the resistor value, the amplifier gain accuracy, and the overall stability of the circuit.
