⚙️ How the 5V 10A Relay Module Works

The 5V 10A Relay Module works by using a small 5V signal from a microcontroller to energize the internal relay coil. When activated:

1. The relay coil becomes magnetized.

2. Internal contacts switch position.

3. The connected load circuit is turned ON or OFF.

This allows safe control of devices such as:

• Lights

• Fans

• Pumps

• Motors

• AC appliances

• Heaters

• Industrial equipment

The relay module provides isolation between the low-voltage control side and high-voltage load side, ensuring safety in automation systems.
