Current to voltage module 0/4-20mA to 0-3.3V5V10V voltage transmitter signal conversion conditioning

 

Product introduction:

Size: 42 * 25.2 mm

In the process of circuit signal transmission, the voltage signal will become weaker as the transmission distance increases. The current transmission can avoid the weakening of the signal. This module is used for the end of the current signal transmission, and converts the signal into a voltage signal for detection by the single chip microcomputer. The current input supports 4-20Ma, 0-20mA, and the voltage output supports 0-3.3V 0-5V 0-10V.

 

Product Highlights:

Wide supply voltage range, output voltage supports multiple ranges;

Both zero and full scale can be adjusted by themselves;

High stability, good linearity, industrial grade;

The current signal sampling resistor adopts high-precision color ring resistance, high precision, small temperature drift and high power.

 

Instructions for use:

1. The 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-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).

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

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

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

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

                     0--10.0V range: J1 1, 2 feet shorted, 3, 4 feet disconnected

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

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

                     0--10.0V range: J1 1, 2 feet shorted, 3, 4 feet disconnected
