## Description

The Gravity I2C 4-20mA DAC Module outputs 0–25 mA of current controlled via I2C, with high-accuracy 4–20 mA output available after calibration (0.2% linearity error). Built around the GP8302 chip, it provides 12-bit resolution and is compatible with Arduino, enabling precise current-loop control of industrial devices such as motors, inverters, valves, and pumps. The module uses a Gravity I2C interface for easy connection and requires an 18–24V power supply (24V recommended). It supports a maximum load resistance of 750Ω at 24V, with a start-up time under 2 ms and operating temperatures from −40°C to 125°C. Key Features 0–25 mA Current Output – 4–20 mA with 0.2% accuracy after calibration 12-Bit Resolution – GP8302 DAC chip (0x000–0xFFF) Gravity I2C Interface – Simple connection to Arduino and compatible boards I2C Address – 0x58 High Level Input – 2.7–5V I2C signal compatible Low Power – Less than 5 mA consumption, under 2 ms start-up Wide Temperature Range – −40°C to 125°C Specifications DAC Chip – GP8302 Power Supply – 18–24V DC (24V recommended) Output Current – 0–25 mA Accuracy – 0.5% before calibration, 0.2% after calibration Max Load Resistance – 450Ω @ 18V, 750Ω @ 24V Power Consumption – <5 mA Start-Up Time – <2 ms Operating Temperature – −40°C to 125°C Ideal For Industrial 4–20 mA current loop control Motor, inverter, valve, and pump automation Function signal generation Equipment debugging and test device prototyping Package Contents 1× Gravity I2C 4-20mA DAC Module 1× Gravity I2C/UART Sensor Connector Resources Product Wiki Schematic (PDF) Dimensions (PDF) Datasheet (PDF)
