Relay Module 4 Channel 5V for Arduino and Microcontroller Projects

Description:
The 4 Channel 5V Relay Module is a robust and user-friendly module designed to control multiple high-current electrical devices using low-current digital signals. This module is highly compatible with Arduino, Raspberry Pi, and other microcontroller platforms, making it an excellent choice for home automation, robotics, and industrial control applications.

Specifications:

Key Features:

• Quad Relay Control: Independently control four devices.
• High Load Support: Suitable for high-current loads up to 10A.
• Optocoupler Isolation: Ensures safety and protects the microcontroller from voltage spikes.
• LED Indicators: Displays the state of each relay channel.
• Wide Compatibility: Designed to work seamlessly with 5V microcontrollers like Arduino, Raspberry Pi, and more.

Applications:

• Home Automation: Manage multiple appliances like lights, fans, and pumps.
• DIY Projects: Control motors, solenoids, or other high-current devices.
• Industrial Automation: Automate machinery with multiple actuators.
• IoT Projects: Integrate with sensors and communication modules for smart control systems.

Usage Tips:

1. Connections:
   • Connect VCC to the 5V output of your microcontroller.
   • Connect GND to the ground.
   • Use IN1, IN2, IN3, and IN4 to control the four relay channels.
2. Logic Control:
   • A high signal (5V) activates the corresponding relay, while a low signal (0V) deactivates it.
3. Safety Precautions:
   • Ensure the load does not exceed the rated capacity of any relay channel.
   • Avoid touching high-voltage connections while the module is powered.
4. Testing: Before connecting to high-voltage devices, test functionality using an LED or multimeter.

The 4 Channel 5V Relay Module is a versatile and essential component for projects requiring reliable control of multiple high-current devices.
