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

Introducing the 4-20mA to 5V Converter for Arduino Industrial Sensor Interface Board. This module simplifies interfacing Arduino, Raspberry Pi, or any other microcontroller with Industrial Sensors and Devices featuring a 4-20mA output. Traditionally, connecting these devices to Arduino or Raspberry Pi has been challenging due to the need for external circuits and tuning to convert the current signal to an analog voltage. However, this board streamlines the process by converting the 4-20mA (or 0-20mA) current signal to a 0-5V, 0-3.3V, or 0-10V analog output voltage. This voltage can be directly connected to the ADC pin of the microcontroller. With convenient onboard screw terminal connectors, establishing connections becomes easy and straightforward.

Note : HW-685 on board working is same.

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:
