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.
NOTE: For higher accuracy, it is recommended to measure with 12 or more bit ADC!
