YYI-4 Current Detection Module DC Over-current Motor Locked Rotor Protection Board Current Sensor Board 30A

Specifications Product model YYI 4 Detection range voltage DC 7 30V current 0 30ADetection accuracy 0 1A 100mA Standby current About 20mARelay output it can control the on off of DC line within 30A With error calibration function it can turn off the display for a long time and reduce power consumption Function Description P 11 when the measured current is greater than I1 the relay is on when the measured current is less than I1 again the relay is off P 12 when the measured current is greater than I1 the relay is closed it is always closed until the power supply of the circuit board is cut off P 21 when the measured current is greater than I2 the relay is on when the measured current is less than I1 the relay is offP 22 when the measured current is greater than I2 the relay is closed it is always closed until the power supply of the circuit board is cut off P 31 when the measured value is less than I1 the relay is on when the current is greater than I2 the relay is off P 32 when the measured current is less than I1 the relay is closed it is always closed until the power supply of the circuit board is cut off P 41 when the measured current is between I1 and I2 the relay is closed and in other cases the relay is disconnected P 42 when the measured current is between I1 and I2 the relay is closed it is always closed until the power supply of the circuit board is cut off P 51 when the measured current is less than I1 or more than I
