DFRobot - Gravity: Analog Current to Voltage Converter(for 4~20mA Application)

This module is designed for 4~20mA current output sensors. It linearly converts 0~25mA current signals into 0~3V voltage signals, allowing your main control board to easily read industrial current signals.

(Note: If your sensor outputs 0-10V voltage signals instead of current, please check the [Gravity: 0-10V 15-Bit High-Precision ADC Module] directly.)

Normally, current signals lower than 4mA can be used for fault diagnosis, and current signals higher than 20mA can be used for overrun detection. Therefore, this module is specially designed with a wide detection range from 0 to 25mA, and compatible with fault detection, overrun detection applications.

This module employs 0.1% high precision sense resistor and ultra-low noise rail-to-rail zero-drift op amp, high accuracy, no need to calibration, so it is convenient to use. 3.3V~5.5V wide voltage power supply, 0~3V voltage signal output, which are compatible with more main control boards, adapt to more applications.

Pro Tip:Want Industrial-Grade Precision? Standard Arduino boards only have 10-bit ADC. For high-precision measurement (15-bit resolution), we highly recommend using this converter together with the [Gravity: I2C High-Precision ADC Module]. This combination creates a professional 4-20mA reading system via I2C interface.
