1-Channel 12V Isolated Relay Module with Optocoupler Trigger

Are you looking for a safe way to control high-voltage heavy appliances using low-voltage microcontrollers? Connecting heavy AC/DC loads directly to your delicate microchip pins invites massive reverse voltage spikes, leading to fried controller boards, system crashes, and dangerous short circuits. If you are a smart home automation builder, robotics student, or industrial IoT developer, the 1-Channel 12V Relay Module is engineered to provide complete electrical isolation while managing large electrical appliances seamlessly.

Why Choose Our 12V Relay Module? (Features vs. Benefits)

  • Integrated Optocoupler Isolation: High-current switching creates a dangerous electromagnetic back-EMF kickback. The on-board sub-component isolates the control circuit completely using a light-driven link, guaranteeing that unexpected high-voltage surges can never travel backward to destroy your sensitive development board.
  • Dual High-Current AC/DC Switching: Weak electronic transistors cannot withstand high load current demands. This heavy-duty mechanical relay handles up to 250V AC at 10A or 30V DC at 10A, letting you safely switch large water pumps, field lights, cooling fans, and solenoid valves.
  • Flexible High/Low Level Trigger Jumper: Hard-coded logic inputs can complicate your micro-coding layout. Featuring an on-board physical jumper pin, you can switch the module’s firing mode between a High-Level signal or Low-Level ground trigger to instantly match your script logic.
  • Dual Status indicator LEDs: Troubleshooting unreactive blind nodes in a massive circuit nest wastes precious bench hours. The board includes a red Power LED to confirm incoming 12V current and a bright green Status LED that glows the exact millisecond the mechanical coil engages.
