Product description: Gravity - 1-channel DAC 4-20mA I2C digital-to-analog converter - DFRobot DFR0972
Digital-to-analog converter equipped with a Gravity series connector. It has two screw connectors - one with a current output in the range of 0 mA to 25 mA , and the other intended for connecting a power supply in the range of 18 V to 24 V DC . The DAC converter is compatible with Arduino , so it can be used with a wide range of peripheral devices such as light controllers, inverters, valves and pumps. The maximum resistance for 18 V power supply is 450 Ohm, and for 24 V up to 750 Ohm.
Product compatible with Arduino!
