The 5V 2-Channel Relay Module is an electronic switching module that allows microcontrollers and other low-voltage control systems to operate two independent circuits. Each channel uses an electromagnetic relay to switch a connected load between its normally open (NO), normally closed (NC), and common (COM) terminals.
Operating with a 5V relay supply, this module is commonly used in Arduino-based projects, automation experiments, and electronic control systems. Its two independent relay channels allow you to control two separate devices or circuits using individual control signals.

Product Note
- Check the relay's printed ratings and the module's documentation before connecting a load. Switching capacity depends on the exact relay model and module design.
- Some versions use active-LOW input signals, while others may have different input configurations.
- Verify the module's logic-level compatibility before connecting it to a 3.3V microcontroller such as an ESP32.
- Electrical safety: Relay terminals can expose hazardous voltages when used with mains-powered equipment. Mains wiring should only be handled by a qualified person using appropriate insulation, enclosures, and protection. Do not work on energized circuits.
