Product Description
Product Introduction
1. Output driving capability: 250VAC-10A, 125VAC-10A, 30VDC-10A
28VDC-10A；
2. Easy to use, each group has a simple 3-wire structure for output, with 6 reserved output terminals
3. Connect the input directly to the Q port of the microcontroller or digital circuit, and input the high-level group
Electrical appliance is closed, input low level relay is released:
4. Working voltage 5V, suction current of about 70mA per circuit, with relay status indicator
Indicator lights;
5. Full surface mount components, the most reasonable driving circuit design, using 8050 transistor
Activate the relay;
6. Equipped with fixed screws for easy installation
Simple test instructions: The module's input and output are electrically insulated for correct use
After pressing, simply connect a high level (such as short circuiting with VCC) to the input pin to make it
The relay is closed, not connected or connected to a low level (such as a short circuit with GND), and the relay does not operate
