Why 4-20 mA Current Loop?

Industrial-grade transducers commonly use current signals to transmit data. This is in contrast to most other transducers, such as thermocouples and resistive strain gages, which use a voltage signal. While voltage-based transducers are sufficient in many environments, current-based transducers are at times preferred. For instance, the inherent disadvantage of using voltage to transmit signals in an industrial environment is voltage drops over long cable lengths due to wire resistance. The 4-20 mA current loop is the main method for transmitting the sensor’s information over a long distance in industrial sensors.

The sensor’s output voltage is converted into a proportional current, 4 mA represents the zero level of the output and 20 mA represents the full-scale output. Then a receiver (current to voltage converter module) at the remote location end converts this 4-20 mA signal back to the voltage which is then processed by a controller (PLC for example) or a display signal.

What does the current to voltage converter do?

This current-to-voltage module linearly converts 4-20mA current signals into 0-3V or 0-5V or 0-10V (Industrial signal). Industrial sensors or devices usually have the current signal output of 4-20 mA. With this current-to-voltage module, your main control board can easily read the current signals output from industrial sensors or devices.


  • Current Input support 4-20Ma & 0-20mA
  • Voltage output support 0-3.3V / 0-5V / 0-10V
  • Zero and maximum sensor output range can be adjusted
  • Power supply: DC 7~36V (if the output needs to be 10V, the input must be over 12V)
  • Reverse polarity protection
