Mạch chuyển tín hiệu DFRobot Gravity: I2C 4-20mA DAC Module (Arduino Compatible)

Mạch chuyển tín hiệu DFRobot Gravity: I2C 4-20mA DAC Module (Arduino Compatible) được sử dụng để chuyển từ giao tiếp I2C sang tín hiệu dòng điện 4-20mA thường được sử dụng trong công nghiệp để điều khiển motor, inverter,...

This is an I2C DAC module that outputs 0-25mA current. It offers a more accurate 4-20mA current output after calibration, which can be used with most 4-20mA devices on markets such as motors, inverters, valves, pumps, etc., by Arduino programming.

FEATURES

• 0-25mA output, more accurate current within 4-20mA available after calibration
• Gravity interface, I2C communication
• High accuracy, 0.2% linearity error
