4 Channel 5V Relay Module with Optocoupler

The 4 Channel 5V Relay Module allows for seamless switching of high-current devices such as lights, motors, or solenoid valves with low-current signals from microcontrollers like Arduino or Raspberry Pi. Each relay can handle up to 10A at 250V AC or 30V DC, ensuring reliable performance in controlling a range of devices. It includes optocoupler isolation, which enhances safety and stability by reducing interference. The module is compact and lightweight, making it suitable for DIY projects, automation systems, and experiments. With screw terminals for secure wiring and status LEDs for monitoring, it's easy to use and integrate into various applications.
