The 5V 4 Channel Relay Module is a high-quality relay board designed for controlling high-voltage appliances and devices with low-voltage microcontrollers like Arduino, Raspberry Pi, ESP8266, and ESP32. It allows easy switching of AC (220V) and DC loads through a simple control signal. With an optocoupler isolation, this module ensures better safety and reliable performance in various automation projects.
Key Features:
- 4 independent relay channels, each supporting AC 250V/10A or DC 30V/10A.
- 5V operating voltage, compatible with Arduino, Raspberry Pi, ESP8266, ESP32, and other microcontrollers.
- Optocoupler isolation for enhanced safety and reduced interference.
- LED indicators for each relay to show its ON/OFF status.
- Trigger voltage: 3.3V – 5V, making it ideal for both 3.3V and 5V logic devices.
- Screw terminals for easy connection of load devices.
- Common (COM), Normally Open (NO), and Normally Closed (NC) contacts for flexible control.
- Applications: Home automation, industrial automation, motor control, smart switches, and IoT projects.
