About 2-Channel Relay
This 2-Channel Relay Module is an essential component for hobbyists and engineers looking to control high-voltage appliances (like lights, fans, or motors) using low-voltage logic signals. It acts as an electrically operated switch, allowing a microcontroller (such as Arduino, ESP32, or Raspberry Pi) to safely switch AC loads up to 250V @ 10A or DC loads up to 30V @ 10A. The module features an active-low trigger logic (common in optocoupler versions), meaning the relay activates when the input signal is pulled to ground. It includes optocoupler isolation to protect your microcontroller from high-voltage spikes and flyback diodes for coil suppression. Each channel has a dedicated LED indicator for status monitoring. It is widely used in home automation, industrial control systems, robotics, and DIY electronics projects.
