4 RELAY MODULE

The 4-Channel Relay Module is a versatile electronic component that allows control of four independent high-voltage devices using low-voltage signals from microcontrollers such as Arduino, Raspberry Pi, or ESP boards. Each channel can switch AC or DC loads safely, making it ideal for home automation, IoT projects, and industrial control systems.

Built with high-quality relays and protection circuits, the module ensures safe operation while isolating low-voltage control signals from high-voltage loads. Its compact design and easy-to-use interface make it perfect for both prototyping and permanent installations.
