Все о продукте
Digital-to-analog converter with Gravity serial connector. It has two channels - one with a current output from 0 mA to 25 mA, and the other - for connecting a 18-24 V DC power supply. The converter is compatible with Arduino, so it can be used with various peripherals, such as light controllers, inverters, valves and pumps. The maximum resistance of the 18 V power supply is 450 ohms, and 24 V - up to 750 ohms. Main features:
- Equipped with GP8403 chip
- Stable output current with small, up to 0.2% error after calibration
- Wide supply voltage range from 18 V to 24 V DC
- Has a Gravity connector and uses an I2C bus for communication
- Consumes less than 5 mA of current
