Gravity: Analog Current to Voltage Converter Module(4~20mA)

SKU: SEN0262

This current-to-voltage module linearly converts 0-25mA to 0-3V, letting main control boards easily read industrial 4-20mA sensor signals. Its wide range supports fault (＜4mA) and overrun (＞20mA) detection. With a 0.1% precision resistor and ultra-low noise rail-to-rail zero-drift op amp, it’s highly accurate and calibration-free. 3.3V-5.5V power fits more main boards. Note: Use 12+ bit ADC for better accuracy.
