Current Detection Module Digital Display Sensor Protective Board Detector Switch DC 7‑30V

1、Current Sensor Module: Can easily detect the DC current and control the on and off of relay according to the set limit current.

2、Wide Detection Range: The voltage detection range is 7‑30V, and the current detection range is 0‑30A, meeting various needs.

3、Accurate Measurement: With a high measurement accuracy up to 0.1A, the sensor module has error calibration function as well.

4、Circuit Protection: Used to limit the current in the circuit and protect electrical equipment from damage caused by the current.

5、Convenient Operation: The digital display can be turned off for a long time to reduce power consumption, useful and convenient.Item Type: Current Detection Module

Product Model: YYI-4

Voltage Detection Range: DC7-30V

Current Detection Range: 0~30A

Detection Accuracy: 0.1A (100mA).

Standby Current: About 20mA.

Relay Output: Can control the on and off of DC lines within 30A.

Function: Detect whether the current is too large or too small, control the relay switch to control the line on and off, or give a signal.

How to Use:

No. 1 Operation Instructions:

1. P-11: When the measured current is greater than I1, the relay is closed; when the measured current is less than I1 again, the relay is disconnected;

2. P-12: When the measured current is greater than I1, the relay is closed; it always stays closed until the circuit board is powered off;

3. P-21: When the measured current is greater than I2, the relay is closed; when the measured current is less than I1, the relay is disconnected;

4. P-22: When the measured current is greater than I2, the relay is closed; it always stays closed until the circuit board is powered off;

5. 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;

6. P-32: When the measured current is less than I1, the relay is closed; it always stays closed until the circuit board is powered off;

7. P-41: When the measured current is between I1 and I2, the relay is closed, otherwise the relay is disconnected;

8. P-42: When the measured current is between I1 and I2, the relay is closed; it always stays closed until the circuit board is powered off;

9. P-51: When the measured current is less than I1 or greater than I2, the relay is closed, otherwise the relay is disconnected;

10.P-52: When the measured current is less than I1 or greater than I2, the relay will be closed; it will always be closed until the circuit board is powered off.

No. 2 Setting Instructions:

1. Power on to display the measured current(if the measured current terminal is suspended, the number of digital display is normal);

2. The first time K1 is pressed, it takes more than 1 second to effective prevent false triggering. The screen displays: P 11: K2 adjustment mode, K3 adjustment function

3. Press K1 for the second time, the screen flashes 0.05 means that the value of the threshold I1 is 0.05A; K2 sets I1 plus, K3 sets I1 minus;

4. 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

5. Press K1 for the fourth time, the screen displays the measured current; it means it enters the standby state;

6. In standby mode, long press K2 or K3 to fine tune the measured current error. 1 x Current Detection Module
