DFRobot Current-to-Voltage Analog Converter 4-20mA - SEN0262 reference ruler Make sure the adapter youThis current to voltage module can linearly convert 0~25mA current signals into 0~3V voltage signals. Industrial sensors or devices usually have the current signal output of 4~20 mA. With this current to voltage module, your main control board can easily attain the current signals input from industrial sensors or devices. Normally, current signals lower than 4mA can be used for fault diagnosis, and current signals higher than 20mA can be used for
