Description
Overview of this 4-20ma to 5v converter for arduino industrial sensor interface board
Feature
- 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).
- After power-up, the D2 indicator should be on, otherwise check the line connection. Board with reverse protection, the reverse does not burn.
- 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).
- 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).
- According to your needs, through the jumper cap to select the appropriate range:
