5v relay module KY-019 1 way relay module

5V relay module KY-019 1-channel relay module expansion board

(Provide detailed descriptions in both Chinese and English)

Chinese description:

1. Output driving capability:250VAC-10A、 125VAC-10A、30VDC-10A、 28VDC-10A；

2. Easy to use, with a simple 3-wire structure for each output and 6 reserved output terminals;

3. Connect the input directly to the microcontroller IO port or digital circuit, with the input high-level relay engaged and the input low-level relay released;

4. Working voltage 5V, suction current approximately70mA per routeEquipped with relay status indicator light;

5. Full surface mount components, the most reasonable driving circuit design, using 8050 transistor to drive relay action;

6. Equipped with fixed screw holes for easy installation, circuit board size1.8cm*4.0cm*1.9cm, heavy15g；

Simple test instructions: The module's input and output are electrically insulated. After supplying the corresponding correct voltage, simply connect a high level (such as short circuiting with VCC) to the input pin to make the relay close. If not connected or connected to a low level (such as short circuiting with GND), the relay will not operate.
