This 2‑channel 5 V relay board is a versatile control interface designed to switch electrical loads using low‑voltage logic signals from microcontrollers such as Arduino, ESP32, and Raspberry Pi. It features optocoupler isolation to protect the control circuitry from high‑voltage interference and ensure reliable operation.

Key Features:

  • Operating Voltage: 5 V DC for relay coils.

  • Two independent relay channels for separate load control.

  • Optocoupler isolation protects microcontroller logic from electrical interference.

  • LED status indicators display the ON/OFF state of each relay.

  • Contact Ratings: up to 10 A @ 250 VAC or 10 A @ 30 VDC per channel – ideal for lights, motors, and appliances.

  • NO/NC/COM terminals for flexible wiring options.

  • Compatible with 3.3 V and 5 V logic levels for easy integration with most microcontrollers.

Ideal for home automation, robotics, IoT, and other projects requiring safe and reliable switching of high‑power devices.
