Product Name:
0-5V/0-10V to 4-20mA/0-20mA Voltage to Current Analog IO Module Transmitter V/I Linear Converter for PLC RS485 Sensor
Packing list:
1 PCS 0-5V/10V/24V to 4-20mA Voltage Controlled Constant Current Source Module

Description:

1 Working voltage: DC 7-30V (the power supply voltage must be greater than the input voltage by more than 2V)
2 Working current: 10-30MA (related to the output current)
3 Voltage signal input range: 0-5V/0-10V/0-24V.
4 current signal output range: 4-20MA
5 Accuracy: 1%
6 Size: 42*21*14mm
7 Weight: 8 grams

This voltage-to-current module can convert 0-5V/0-10V/0-24V voltage into 4-20MA output.
It can also be adjusted to any range within 24V by adjusting the potentiometer on the board, such as:
0-2.5V
0-3.3V
0-4.096V
0-5V
0-10V
0-15V
0-20V
0-24V
Notice:
1 In order to adjust the parameters more accurately, please let the board output 20MA current for 3 minutes before calibration
2 The power supply voltage must be greater than the input voltage by 2V or more
3 The current output cannot be greater than 30MA, otherwise it is easy to burn the chip
4 Potentiometer adjustment method: LOW: clockwise becomes smaller, counterclockwise becomes larger; HIGH: clockwise becomes larger, counterclockwise becomes smaller

Wiring Diagram:
Demo :
If the output current is not accurate, it can be calibrated:
1 Wire according to the above diagram. VCC/GND is connected to power supply; OUT/GND is connected to 4-20MA ammeter; Vi+/Vi- is connected to voltage signal source
2 Input 0V voltage signal, adjust the LOW potentiometer, let the current output 4.00MA
3 Adjust the voltage signal to the highest level (5V/10V/24V), adjust the HIGH potentiometer, and let the current output 20.00MA
Demo :
We only provide 0-5V/0-10V/0-24V version, but you can adjust the range you need by adjusting the potentiometer.
For example: You bought a 0-5V version and you want to change it to a 0-10V version:
1 Wire according to the above diagram. VCC/GND is connected to power supply; OUT/GND is connected to 4-20MA ammeter; Vi+/Vi- is connected to voltage signal source
2 Input 0V voltage signal, adjust the LOW potentiometer, let the current output 4.00MA
3 Input 5V voltage signal, adjust the HIGH potentiometer, let the current output 10.00MA
4 Input 10V voltage signal, adjust the HIGH potentiometer, let the current output 20.00MA
