4-20mA to 5V Converter for Arduino Industrial Sensor Interface Board

Description

This module lets you interface your Arduino/Raspberry Pi or any other microcontroller with Industrial Sensors and Devices with a 4-20mA output. Interfacing these devices with Arduino/Raspberry Pi has always been tough and complex due to the external circuits, tuning required to convert the current signal to an analog voltage. This board takes care of this and converts the 4-20mA (or 0-20ma) current signal to a 0-5V or 0-3.3V or 0-10V analog output voltage which can be directly connected to the ADC pin of the microcontroller. Connections are easy and simple with the onboard screw terminal connectors!

Application

This module is used to convert the current signal to voltage Output.

Instructions for use:

1. The module according to the definition of wiring, power supply voltage 7-36V (if the output to 10V, the supply voltage must be greater than 12V).
2. After power-up, the D2 indicator should be on, otherwise check the line connection. Board with reverse protection, the reverse does not burn.
3. When the current input is the minimum (0mA or 4mA), adjust the ZERO potentiometer so that the VOUT output is the minimum (0.0V or other voltage).
4. When the current input is at maximum (20mA), adjust the SPAN potentiometer so that the VOUT output is the maximum (3.3V or 5V or 10V, the output can be as low as 2.5V when the input is 4-20ma).
5. According to your needs, through the jumper cap to select the appropriate range:
