Current To Voltage Converter Module

This Module is used to convert current signal to voltage Output. It is used for the end of the current signal transmission, the signal into a voltage and signal for single-chip detection. It has a current Input support of 4-20mA, 0-20mA and voltage output support of 0-3.3V, 0-5V and 0-10V.

In the process of circuit signal transmission, the voltage signal will increase with the transmission distance becomes weak, the use of current transmission can avoid the signal weakening.

Features:

• Wide supply voltage range, the output has multiple voltage 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

Specifications:

• Current Input support 4-20mA & 0-20mA

• voltage output support 0-3.3V, 0-5V and 0-10V

Instructions for use:

• 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).

• After power-up, the D2 indicator should be on, otherwise check the line connection. Board with reverse protection, reverse does not burn.

• 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).

• 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:

4–20mA:

• 0-2.5V: J1 1,2 pin are short circuit connected; 3, 4 pin are short circuit connected
• 0-3.3V: J1 1,2 pin are disconnected; 3, 4 pin are disconnected
• 0-5V: J1 1,2 pin are short circuit connected; 3, 4 pin are short circuit connected
• 0-10V: J1 1,2 pin are short circuit connected; 3, 4 pin are disconnected

0–20mA:

• 0-3.3V: J1 1,2 pin are short circuit connected; 3, 4 pin are short circuit connected
• 2. 0-5V: J1 1,2 pin are short circuit connected; 3, 4 pin are short circuit connected
• 3. 0-10V: J1 1,2 pin are short circuit connected; 3, 4 pin are disconnected
