HW-685 Current to Voltage Module 0/4-20mA to 0-3.3V/5V/10V Voltage Transmitter Signal Converter
Instructions for use:
1. The module is wired according to the definition, the power supply voltage is 7-36V (if the output is to 10V, the supply voltage must be greater than 12V)
2. After power-on, the D2 light should be on, otherwise check the line connection. The board is reversely protected, and the reverse connection does not burn.
3. When the current input is at the minimum value (0mA or 4mA), adjust the ZERO potentiometer to make the VOUT output the minimum value (0.0V or other voltage).
4. When the current input is at the maximum value (20mA), adjust the SPAN potentiometer to make the VOUT output the maximum value (3.3V or 5V or 10V. When the input is 4-20ma, the output can be as small as 2.5V)
