USB_HRF1206 多功能數據採集卡－天天向上

1. 電壓 0-電壓7為類比電壓信號檢測,檢測電壓信號範圍為0-10V;

2. 電流 0-電流3為8路電流信號輸入檢測,檢測電流範圍為0-20mA;

3. DAC0-DAC1 為類比電壓信號輸出, 電壓信號輸出範圍為0-10V;

4. PWM0-PWM5為PWM信號輸出端, 其中PWM0-PWM3占空比和頻率都可單

獨設置; PWM4和PWM2的頻率一樣, PWM5和PWM3的頻率一樣, 占空比可

單獨設置;

5. DO0-DO7為8 路數位信號輸出，低電平為0V，高電平為3.3V;

6. DI0-DI7 為8路數位信號輸入, 其中, DI0-DI3默認為高電平, DI4-DI7 默認為低

電平，可檢測的高電平為3.3V或5V，低電平為0V;
