Product brief:
In the process of circuit signal transmission, the voltage signal will weaken with the increase of the transmission distance, and the current transmission can avoid the weakening of the signal. The module is used for the end of current signal transmission, the signal is converted into voltage signal for SCM detection. The current input supports 4-20Ma and 0-20mA, and the voltage output supports 0-3.3V 0-5V 0-10V.
Product highlights:
The power supply voltage range is wide, and the output voltage supports multiple ranges;
Zero and full range can be adjusted automatically;
High stability, good linearity, industrial grade;
The sampling resistor of current signal adopts high precision color ring resistor, which has high precision, small temperature drift and high power
Instructions:
The 1. module is connected according to the definition, the 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 bright, otherwise please check the line connection. Board with reverse connection protection, reverse connection not burning.
3. when the current input is minimum (0mA or 4mA), adjust the ZERO potentiometer, so that the output of VOUT is minimum (0.0V or other voltage)
4. when the current input is the maximum (20mA), adjust the SPAN potentiometer, so that the VOUT output is the maximum value (3.3V or 5V or 10V, when the input is 4-20mA, the minimum output can be 2.5V).
According to your needs, select the corresponding range by jumper cap:
4--20ma:0--2.5V range: J1 1, 2 feet short connection, 3, 4 feet short connection
0--3.3V range: J1 1, 2 feet off, 3, 4 feet off
0--5.0V range: J1 1, 2 feet short connection, 3, 4 feet short connection
0--10.0V range: J1 1, 2 feet short connection, 3, 4 feet off
0--20ma:0--3.3V range: J1 1, 2 feet short connection, 3, 4 feet short connection
0--5.0V range: J1 1, 2 feet short connection, 3, 4 feet short connection
0--10.0V range: J1 1, 2 feet short connection, 3, 4 feet off
