Relay Module 1 2 4 6 8 Channel 5v With Optocoupler Projects Arduino Compatible
Relay Module (1, 2, 4, 6, or 8 Channel) is a 5V-controlled relay board designed for switching high-voltage AC or DC devices using low-voltage microcontrollers like Arduino, Raspberry Pi, ESP32, and others. Each channel features a high-quality mechanical relay rated at 10A/250V AC or 10A/30V DC, perfect for home automation, smart systems, and electronics projects.
Integrated optocouplers provide electrical isolation, protecting your microcontroller from voltage spikes and interference. The board includes status LEDs, screw terminals, and trigger inputs, making it easy to integrate into any DIY or industrial project.
