LinkMejor DC Current Detection Relay Module 0-30A with Overcurrent Protection

Overview

• Range: DC current detection relay module measures 0 30A with 0.01A accuracy for precise monitoring.
• Power: Sensing module can turn off LED display to reduce energy use.
• Control: Voltage relay module allows current limit setting for circuit protection.
• Calibration: Overcurrent protection module includes error calibration for accuracy.
• Use: Current tester indicator safeguards equipment from damage due to current surges.

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, electrical equipment from damage caused by current. Specification: Model: -4 Supply voltage: DC 7-30V Detection range: DC 0-30A Accuracy: 0.01A (10mA) Standby current: About 20mA Weight: Approx. 86g/3.0oz 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; : When the measured current <
