4-20mA To 0-3.3V, 5V, 10V Voltage convertor

• Wide supply voltage range, the output voltage to support multiple ranges
• Zero and range can be adjusted
• High stability, good linearity, industrial grade
• Current signal sampling resistor with high precision color ring resistance, high precision, temperature drift small, high power

1. 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, 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)

 According to your needs, through the jumper cap to select the appropriate range:

4 - 20 mA :  0 - 2.5 V range : J1 1,2 feet short, 3,4 feet shorted

                  0 - 3.3 V range : J1 1,2 feet off, 3,4 feet off

                  0 - 5.0 V range : J1 1,2 feet short, 3,4 feet shorted

                  0 - 10.0 V range : J1 1,2 feet short, 3,4 feet off

0 - 20 mA : 0 - 3.3 V range: J1 1,2 feet short, 3,4 feet shorted

                 0 - 5.0 V range: J1 1,2 feet short, 3,4 feet shorted

                 0 - 10.0 V range: J1 1,2 feet short, 3,4 feet off
