This 2-Channel I2C DAC module from DFRobot can output a voltage of 0-10V, which is a standard driver in industrial applications. It can be widely used with most 0-10V devices on the market such as light controllers, inverters, valves and pumps – all via Arduino programming with a compatible development board. This module supports 8 different I2C addresses, which can be changed using the onboard DIP switch, allowing a cascade of 16 devices. The module comes complete with a compatible Gravity I2C/UART cable. Connection Example Features Support 3.3V-5V power supply Output voltage error is less than 0.5% Output short-circuit protection Two-channel 0-5V/0-10V output for connecting to and controlling standard analog voltage devices Gravity interface, I2C communication, Arduino control, suitable for program automation control Adjustable 8-way I2C addresses, able to control 16 devices at the same time Specifications Operating Voltage: 3.3V~5V I2C Interface: PH2.0-4P (Gravity Line Sequence) Chip Type: GP8403 Input Signal: 12Bit (0x000 – 0xFFF) Input I2C Signal High Level: 2.7V – 5V VOUT0 Output Voltage: 0 – 10V VOUT1 Output Voltage: 0 – 10V Output Voltage Error: 0.5% Linearity Error of Output Voltage: 0.1% Power Consumption: 4mA Output Short-circuit Protection Resources Product wiki Schematics Dimensions 3D File 2D_CAD File GP8403 Datasheet Package Contents 1x Gravity: 2-Channel 0-10V I2C DAC Module 1x Gravity I2C/UART Sensor Cable
