Isolation: The relay provides electrical isolation between the low-voltage control side (Arduino) and the high-voltage load side, ensuring safety during operation.
Easy Integration: The module is designed to be compatible with most Arduino boards. It often comes with clearly labeled pins and can be connected easily using jumper wires.
Indicator LED: Many relay modules feature an LED that indicates whether the relay is activated, making it easier to debug and monitor.
Operating Voltage: Most 1 Channel Relay Modules operate on 5V DC, making them perfect for direct use with Arduino without the need for additional voltage regulation.
1, On-board precision micro-current transformer
2, On-board high-precision op-amp circuit, to do accurate sampling and appropriate compensation and other functions to signal
3, The module can measure AC current within 5A, corresponding output analog can be adjusted
4, Under ideal conditions, the input voltage VCC is 3-35V, according to the potentiometer (adjust the amplification ratio, amplification range 0-100 times) to adjust the required output voltage, but the output (OUT) of the maximum voltage does not exceed 1 / 2 VCC.
5, The output signal is the AC voltage signal, and the output signal voltage does not exceed the maximum 1 / 2VCC.
6, PCB board size: 38 (mm) x 18.5 (mm)
