2-Channel Relay Module with Optocoupler – Arduino Relay Board (5V)

This 2-Channel Relay Module allows your Arduino, Raspberry Pi, or any other microcontroller to control high voltage devices like lights, fans, motors, and appliances. Featuring onboard optocouplers for electrical isolation, this module ensures safe and stable switching of both AC and DC loads.

Key Features:

• 🔌 Relay Channels: 2 (independent control)
• ⚡ Operating Voltage: 5V DC
• 🔒 Isolation: Optocoupler protection for safe operation
• 💡 Max Load: 10A at 250V AC or 10A at 30V DC
• 📘 Control Logic: Active LOW
• 📦 Onboard Indicators: LEDs show relay status
• 🔩 Mounting: 4 mounting holes for easy installation

Applications:

• 🏠 Home automation projects
• 🔌 AC appliance control
• 💡 Lighting systems
• 🚪 Door lock control systems
• 📟 IoT & Smart Home solutions
• 📊 Industrial control systems

How to Use:

1. Connect VCC and GND to your 5V power source or microcontroller.
2. Connect IN1 and IN2 to the GPIO pins of Arduino or ESP32.
3. Use digitalWrite to turn relays ON or OFF (active LOW logic).
4. Connect your high-voltage load to the relay terminal (NO/COM).

Package Includes:

• 1 × 2-Channel Relay Module (with optocoupler)
