I2C 4-20mA DAC Module

This is an I2C DAC module that outputs 0-25mA current. It allows you to make your own 4-20mA sensor for establishing robust and long distance wired communications. This board offers a more accurate 4-20mA current output after calibration, which can be used with most 4-20mA devices on markets such as motors, inverters, valves, pumps, etc.SpecificationChip Type: GP8302Input Signal Range: 12Bit, 0x000-0xFFF (0-25mA)Input I2C Signal High Level: 2.7V-5VPower Supply: 18V-24V (24V recommended)Accuracy: 0.5% before calibration, 0.2% after calibrationPower Consumption: 5mAStart-up Time: 2msOperating Temperature: -40C to 125CLoad Resistance: Maximum 450 load capacity for 18V power supply, maximum 750 for 24VLoad Resistance recommended for Arduino:220~650 (greater than 1/8 watt)Output Current: 0-25mAI2C Address: 0x58Hardware Connection ExampleHow to read the current through the resistorDocumentsProduct wiki V1.0LibrarySchematicsDimensions3D File2D_CAD FileGP8403 Datasheet
