DC current detection relay module digital display overcurrent alarm switch controller motor stall protection 12V 10A Overcurrent Protection Relay Module Current Detection Board 12V relay output control Board Product Description: 1. Using high-quality materials, the quality is guaranteed 2. Detect that the current is too large or too small, control the relay switch to control the circuit on and off, or give a signal 3. Exquisite appearance 4. Good performance and long service life 5. Simple operation and wide application range Parameter: Detection range: DC current between 0~10A Detection accuracy: 0.01A (10ma) With error calibration function, the display can be turned off for a long time, reducing power consumption Standby current: about 20ma Relay output: can control the on-off of the DC line within 5A Function Description: P-11: When the measured current is greater than I1, the relay pulls in; when the measured current is less than I1 again, the relay is disconnected P-12: When the measured current is greater than I1, the relay pulls in; it always keeps pulling in until the power supply of the circuit board is cut off P-21: When the measured current is greater than I2, the relay pulls in; when the measured current is less than I1, the relay is disconnected P-22: When the measured current is greater than I2, the relay pulls in; it always keeps pulling in until the power supply of the circuit board is cut off P-31: When the measured current is less than I1, the relay is closed; when the current is greater than I2, the relay is disconnected P-32: When the measured current is less than I1, the relay pulls in; it always keeps pulling in 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 pulled in, and the relay is disconnected in other cases; P-42: When the measured current is between I1 and I2, the relay pulls in; it always keeps pulling in until the power supply of the circuit board is cut off P-51: When the measured current is less than I1 or greater than I2, the relay is pulled in, and the relay is disconnected in other cases; P-52: When the measured current is less than I1 or greater than I2, the relay pulls in; it always remains closed until the power supply of the circuit board is cut off Setup Instructions: Power on to display the measured current; (if the measured current terminal is floating, the digital display is a normal phenomenon) It takes more than 1 second to press K1 for the first time to prevent false triggering. The screen displays: P 11: K2 adjustment mode, K3 adjustment function Press K1 for the second time, the screen flashes and displays: 0.05 means the value of the threshold I1 is 0.05A; K2 sets I1 plus, K3 sets I1 minus Press K1 for the third time, the screen flashes: 0.10 means the value of the threshold I2 is 0.1A; K2 sets I2 plus, K3 sets I2 minus Press K1 for the fourth time, the screen displays the measured current ; it means entering the standby state; Long press K2 or K3 in standby state to fine-tune the measured current error Packing list: Current detection module*1 _x000D_
