DFR0972

DFR0972 is a Gravity: I2C 4-20mA DAC module (Arduino compatible). This I2C DAC module outputs 0-25mA current and 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. Typical applications include function signal generator, automatic controller for lighting or fountain, automatic and quick transformation of small equipment, electromechanical equipment debugging and transformation of small test device.
