7-30V 0-30A DC Current Detection Sensing Module Current Transformer Sensor Current Tester Indicator Overcurrent Protection Relay Module
Function description: P-11: When the measured current > I1 (low limit current), the relay closed; When the measured current < I1, the relay opens; P-12: When the measured current > I1, the relay closes; Maintain the state until the circuit board power off; P-21: When the measured current > I2 (high limit current), the relay closes; When the measured current < I1, the relay opens; P-22: When the measured current > I2, the relay closes; Maintain the state until the circuit board power off; P-31: When measured < I1, the relay closes; When the current > I2, the relay opens; P-32: When the measured current < I1, the relay closes; Maintain the state until the circuit board power off; P-41: When the measured current is between I1 and I2, the relay closes, opens in other cases; P-42: When the measured current is between I1 and I2, the relay closes; Maintain the state until the circuit board power off; P-51: When the measured current < I1 or > I2, the relay closes, opens in other cases; P-52: When the measured current < I1 or > I2, the relay closes; Maintain the state until the circuit board power off. Features: This module can detect the DC current value, control the on-off of the relay according to the limit current set by users. Detection range is DC 0-30A with the accuracy of 0.01A. With error calibration function. Can turn off the LED display to reduce power consumption. Can be used to limit the current in the circuit, protect electrical equipment from damage caused by current.
