I2C is a communication protocol that allows devices to exchange data with each other over a two-wire interface. It is commonly used in embedded systems and allows devices to communicate with a microcontroller or computer.

The DAC (Digital-to-Analog Converter) module you described is used to convert a digital signal into an analog current. The output range of 0-25mA is the maximum range that the DAC can output, but it can be calibrated to a more accurate 4-20mA range, which is commonly used in industrial control systems.

To use the DAC module with an Arduino, you will need to connect the DAC module to the Arduino using the I2C bus. You will also need to install a library for the DAC module and write code to control the output of the DAC. Once you have set up the hardware and written the necessary code, you can use the Arduino to control the output of the DAC module and send a 4-20mA current to most 4-20mA devices, such as motors, inverters, valves, pumps, etc.

  • 0-25mA output, more accurate current within 4-20mA available after calibration
