## Description

This 2-Channel I2C DAC module 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 markets such as light controllers, inverters, valves, pumps, etc, by Arduino programming.Besides, this module supports 8 different I2C addresses, which can be changed using the on-board DIP switch, allowing a cascade of 16 devices. FeaturesSupport 3.3V-5V power supplyOutput voltage error is less than 0.5% Output short-circuit protectionTwo-channel 0-5V/0-10V output for connecting to and controlling standard analog voltage devicesGravity interface, I2C communication, Arduino control, suitable for program automation controlAdjustable 8-way I2C addresses, able to control 16 devices at the same timeApplicationsIntelligent function signal generatorAutomatic controlling of lighting or fountainAutomatic and quick transformation of small equipmentAutomatic debugger for electromechanical equipmentTransformation of small test equipmentSpecificationOperating Voltage: 3.3V~5VI2C Interface: PH2.0-4P (Gravity Line Sequence)Chip Type: GP8403Input Signal: 12Bit (0x000 - 0xFFF)Input I2C Signal High Level: 2.7V - 5VVOUT0 Output Voltage: 0 - 10VVOUT1 Output Voltage: 0 - 10VOutput Voltage Error: < 0.5%Linearity Error of Output Voltage: 0.1%Power Consumption: < 4mAOutput Short-circuit Protection DocumentsProduct wikiSchematicsDimensions3D File2D_CAD FileGP8403 DatasheetShipping ListGravity: 2-Channel 0-10V I2C DAC Module × 1Gravity I2C/UART Sensor Cable × 1
