โมดูลแปลงกระแสเป็นโวลต์ Current to voltage module 0/4-20mA to 0-3.3V 5V 10V voltage transmitter signal conversion
โมดูลนี้ใช้สำหรับ แปลงสัญญาณอินพุตกระแสไฟฟ้า 4-20mA หรือ 0-20mA ให้เป็นสัญญาณแรงดันไฟฟ้า 0-3.3V หรือ 0-5V หรือ 0-10V สามารถกำหนดตั้งค่าได้ที่ จัมเปอร์บนโมดูล
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 according to the definition, 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. 0 V 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 ).
