Detailed Description:

The 5V 2-Channel Relay Module is designed to switch high voltage, high current loads using standard 5V logic from microcontrollers. It features opto-isolation for electrical protection, and screw terminals for easy wiring. Each relay can handle up to 250V AC or 30V DC at 10A, allowing control of bulbs, fans, motors, and other household or industrial appliances.

The module includes indicator LEDs for each relay and a low-level trigger interface. It’s perfect for applications in IoT, home automation, industrial control, and remote switching.

Key Features:

• 2 independent relay channels (SPDT – Single Pole Double Throw)

• Opto-isolated inputs for safety

• Low-level trigger compatible with 5V logic (Arduino, ESP, etc.)

• LED indicators for relay status

• Supports both AC and DC loads

• Screw terminal blocks for secure wiring

• Relay switching time: <20ms

• Pre-drilled holes for easy mounting

• Durable PCB with copper traces

Technical Specifications:

How to Use:

1. Connect VCC to 5V and GND to ground of your microcontroller.

2. Connect IN1 and IN2 to GPIO pins of Arduino/ESP/Raspberry Pi.

3. Write logic to send LOW signal to activate each relay.

4. Wire your AC/DC appliances using the screw terminals (COM, NO, NC).

5. Add flyback diodes when driving inductive loads.
