Arduino 4 Channel 5V Relay Module With Optocoupler

Description

Unlock the power of home automation and control high-voltage appliances with ease using the Arduino 4 Channel 5V Relay Module with Optocoupler. This versatile module features four high-quality relays, each integrated with current buffers, allowing seamless connection to your Arduino or microcontroller. Perfect for DIY electronics enthusiasts and automation projects, this relay module provides a simple yet reliable way to control devices like motors, lights, fans, and other household appliances.

Each relay on the module is rated to handle up to 230V AC or 30V DC with a 10A current capacity, ensuring safe and efficient operation even with high-power loads. The module also integrates optocouplers for added protection, isolating your control circuit from the high-power circuits, making it ideal for sensitive electronics and preventing potential damage.

Key Features:

• High Power Control: Rated for up to 230V AC or 30V DC at 10A, this module enables you to control high-power devices easily and safely.
• Multiple Relays: The board features four independent relays, each with a normally open (NO) and normally closed (NC) contact, giving you flexibility in managing different devices simultaneously.
• Optocoupler Protection: Built-in optocouplers provide electrical isolation, protecting your low-voltage circuits from high-voltage spikes and ensuring reliable operation.
• Easy Integration: Powered by a 5V DC supply, this module connects seamlessly to your Arduino or microcontroller. It’s designed to work with both DC and AC signals, making it suitable for a wide range of applications.
• User-Friendly Indicators: The module features five LEDs—one for power and four for indicating the status of each relay, so you can easily monitor the state of your system.

How to Use:

• VCC: Supply voltage (5V from Arduino)
• IN1, IN2, IN3, IN4: Control pins for each relay (set HIGH to activate the relay)
• GND: Ground connection

Whether you’re building a smart home system, automating appliances, or experimenting with new projects, the Arduino 4 Channel 5V Relay Module with Optocoupler provides the power, protection, and convenience you need to get the job done.
