12V 0-10A DC Current Detection Module Current Sensing Detecting Delay Relay Control

Features:
Detecting range: DC 0~10A; accuracy: 0.01A(10mA).
Detect the current to control the relay then control the circuit on/off.
Set delay time to prevent output shock so as to protect the circuit.
With error calibration function.
Can turn off the LED display to reduce power consumption.
Functions Description:
P-1: Over-current Detection: when the detecting currentI1(low limit setting), the relay closes; I2(high limit setting), the relay opens.
P-2: Under-current Detection: when the detecting currentI2, the relay closes; I1, the relay opens.
P-3: Close in the Range: when the detecting current is between I1 and I2, the relay closes; relay opens in other situation.
P-4: Open in the Range: when the detecting current is between I1 and I2, the relay opens; relay closes in other situation.
P-5: Error Calibration and Delay Time Setting: the relay would not operate.
Buttons Description:
K1: Modes Selection;
K2: +
K3: -
Long press K1 for 2s into modes selection; short press K1 to select function and K2 to enter the mode.
Note:
After power on, the LED digits would pulse if the detecting current terminal is none.
