Description

This 5V 4-channel relay module is a useful interface board that lets you control four high-power devices like lights, fans, or motors with microcontrollers like Arduino, ESP32, or Raspberry Pi. It uses standard electromechanical relays with opto-isolators for safety and durability.

Each channel can be triggered individually and can handle high voltages and currents, making it ideal for home automation, DIY control systems, and industrial electronics.

Features:

• 4 separate relay channels

• Trigger level can be set to HIGH or LOW using jumpers

• Control AC or DC loads up to 10A

• Opto-isolation for safe signal separation

• Onboard power and status LEDs

• Easy screw terminals for load connection

• Suitable for automation and IoT projects

Specifications:

• Operating Voltage: 5V DC
