The 2-Channel 12V Relay Module allows you to control two high-power devices independently using low-voltage signals from a microcontroller such as Arduino. Each channel features an optocoupler-isolated relay with normally open (NO) and normally closed (NC) terminals for flexible switching configurations.

Designed for easy integration, the module includes indicator LEDs for relay status and screw terminals for secure high-voltage connections.

Key Features

  • 2 Independent Channels – Control two devices separately
  • 12V Relay Coils – Requires 12V supply for relay operation
  • Optocoupler Isolation – Protects your microcontroller from high-voltage feedback
  • Screw Terminals – NO, NC, and COM connections per channel
  • Status LEDs – Visual indication of relay state
  • Low-Level Trigger – Activate relays with a LOW signal from your microcontroller

Ideal For

  • Home automation and smart switching
  • Motor and pump control
  • Lighting control systems
  • Arduino and microcontroller relay projects
