5V 2 Channel Relay Module

The 5V 2 Channel Relay Module is designed to switch two separate electrical loads using low-voltage control signals from a microcontroller. Each relay channel can control devices such as lights, motors, fans, pumps, and other electrical appliances.

The module includes relay drivers, protection circuitry, and status LEDs to ensure stable and reliable operation. Each channel can be triggered independently using a digital signal, making it suitable for automation systems where multiple devices need to be controlled.

Because relays provide electrical isolation, the control circuit remains protected from high-voltage loads.

Key Features

• Dual relay channels for controlling two devices

• 5V operating voltage compatible with most microcontrollers

• Independent control for each relay

• Supports AC and DC load switching

• Onboard LED indicators for relay status

• Easy interface with Arduino and other controllers
