DFROBOT Gravity 2-Channel I2C DAC Module 0-10V

The DFROBOT Gravity 2-Channel I2C DAC Module provides a reliable solution for outputting a standard 0-10V analogue voltage, making it an ideal driver for various industrial applications. Designed for seamless integration, this module supports both 0-5V and 0-10V output across its two channels, allowing you to connect and control standard analogue voltage devices with ease.

Engineered for precision, the module boasts an output voltage error of less than 0.5%. Safety is also a priority; featuring Over-Current Short Circuit Protection (OSCP), the chip automatically enters protection mode and halts output if a short circuit between the output and GND occurs.

Utilising the Gravity interface and I2C communication, this DAC module is easily controlled via Arduino for program automation. The on-board DIP switch allows you to adjust between 8 different I2C addresses, enabling you to cascade and control up to 16 devices simultaneously. It supports a versatile 3.3V to 5V power supply, ensuring compatibility with a wide range of microcontrollers.

Applications
