Current To Voltage Module 0/4-20mA

Current signal sampling resistance adopts high precision colour ring resistance with high precision, low temperature drift and high power. In the process of transmission of circuit signal, the voltage signal will weaken with the increase of transmission distance.

Current To Voltage Module Instructions:

1. The Current To Voltage Module is wired as defined, and the power supply voltage is 7-36V (if the output is 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).
5. According to your needs, through the jumper cap to select the appropriate range:
6. 4–20ma:
   1. 0-2.5V: J1 1,2 pin are short circuit connected; 3, 4 pin are short circuit connected
   2. 0-3.3V: J1 1,2 pin are disconnected; 3, 4 pin are disconnected
   3. 0-5V: J1 1,2 pin are short circuit connected; 3, 4 pin are short circuit connected
   4. 0-10V: J1 1,2 pin are short circuit connected; 3, 4 pin are disconnected
