描述

多功能可調整式 電流轉電壓模組 0/4-20mA 轉 0-3.3V5V10V 電壓變送器 信號轉換板

在電路信號傳輸的過程中電壓信號會隨著傳輸距離的增加而變弱，採用電流傳輸可以避免信號的變弱。本模塊用於電流信號傳輸末端，將信號轉換成電壓信號供單片機檢測。電流輸入支持 4-20 Ma 、 0-20mA ，電壓輸出支持 0-3.3V 0-5V 0-10V 。

電流轉電壓模組 產品亮點：

• 供電電壓範圍寬，輸出電壓支持多個量程；
• 零點和滿量程都裡可以自行調節；
• 穩定性高，線性度好，工業級；
• 電流信號採樣電阻採用高精度色環電阻，精度高，溫漂小，功率大。

電流轉電壓模組使用說明：

1.   模塊按定義接線，供電電壓 7 -36V （若輸出要到10V ，供電電壓必須大於12V ）

2.   上電後，D2 燈應當亮，否則請檢查線連接。板子帶反接保護，反接不燒。

3.   當電流輸入為最小值（0mA 或4mA ）時，調整ZERO 電位器，使VOUT輸出為最小值（0 .0 V 或其他電壓）

4.   當電流輸入為最大值（20mA ）時，調節SPAN 電位器，使VOUT 輸出為最大值（3.3V 或5V 或10V ，當輸入是 4-20ma 時，輸出最小可以到2.5V ）。

根據您的需求，通過跳線帽選擇相應的量程：

4–20ma ：    0–2.5V 範圍：   J1 1 、2 腳短接，3 、4 腳短接

0–3.3V 範圍：   J1 1 、2 腳斷開，3 、4 腳斷開

0–5.0V 範圍：   J1 1 、2 腳短接，3 、4 腳短接

0–10.0V 範圍：J1 1 、2 腳短接，3 、4 腳斷開

0–20ma ：    0–3.3V 範圍：   J1 1 、2 腳短接，3 、4 腳短接

0–5.0V 範圍：   J1 1 、2 腳短接，3 、4 腳短接

0–10.0V 範圍：J1 1 、2 腳短接，3 、4 腳斷開

Current to Voltage Converter Module Amp to Volt 0/4-20mA to 0-3.3V 0-5V 0-10V Voltage Transmitter Signal Converter Board

• This module is designed for that voltage signal will become weaker with the increase of transmission distance through the process of circuit signal transmission, this module can avoid it.
• Voltage transmitter will be powered by 7-36V, current input range is 4-20mA/0-20mA, voltage output range is 0-3.3V/0-5V/0-10V.
• Zero and full range can be adjusted as your needs; the module is with high stability, good linearity, industrial grade.
• The current signal sampling resistor using high-precision color ring resistance, offers high accuracy, small temperature drift and high power.
• Signal converter is designed with reverse connection protection, if wires connect reversely, it will protect the module from burning

Spec

1. Power supply: 7-36V (if the output needs to be 10V, the input must be over 12V)
2. After power on, the D2 indicator should be on. Otherwise, please check the wiring.
3. The product has reverse polarity protection.
4. When the current input is at minimum (0mA or 4mA), adjust the Zero potentiometer to make the voltage output to be the minimum value (0.0V or others).
5. When the current input is at maximum (20mA), adjust the Span potentiometer to make the voltage output to be the maximum value (3.3V or 5V or 10V; the output can be as low as 2.5V when the current input is within 4 -20mA).

According to your needs, select the appropriate span through the jumper cap:
ON: jumper cap buckles on the two jumper pins
OFF: two jumper pins without the jumper cap
