1 Channel 12V Relay Module with Optocoupler

The ADIY 1-Channel Relay Module with Optocoupler operates on a 12V power supply. This module offers bidirectional isolation and enables control of the relay pull through a choice of high or low levels, based on user requirements. It features a genuine high-quality power relay, a subminiature package optocoupler, a high-power high-voltage transistor, and red and blue signal indicators. The module's layout board is thoughtfully designed to ensure comprehensive stability and reliable performance, making it suitable for a wide range of power control applications. The maximum load for the normally open interface is AC 250V/10A and DC 30V/10A. Moreover, it utilizes high-quality ultra-small optocouplers with excellent anti-interference capabilities and stable performance, requiring only a trigger current of 3mA.


  • Equipped with high-current relay 10A@250VAC / 10A@30VDC
  • It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc.
  • High-quality screw terminals (Terminal Block) provided (C, NC, NO) for quick and easy connection
  • A freewheeling diode to protect your microcontroller
  • Input Signal Pin connected to Burg stick for easy accessibility
  • LED status indicators to indicate the relay ON/OFF status
  • Mounting holes provided
  • Signal input with a high-level signal, the common and often start conduction;
  • The relay can directly control all kinds of equipment and load;
  • One often opened a normally closed contact;
  • Blue KF301 terminal line more convenient.

1. What is a 12V relay module?

  • 1-Channel 12V Relay Module is a 12V 1-channel relay interface board with a screw terminal, it can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, and so on.

2. What is the use of a single-channel relay module?

  • The Single Channel Relay Module is a convenient board that can be used to control high voltage, and a high current load such as motor, solenoid valves, lamps, and AC load. It is intended to communicate with microcontrollers such as Arduino, PIC, and others.

3. When would you use a 12V relay?

  • 12V DC relay switches are the best solution for full voltage applications because they allow a low current flow circuit to control a high current flow circuit, such as a vehicle's horn, headlights, auxiliary lamps, fan motors, blower motors, and countless other pieces of equipment.

4. How does a relay board work?

  • Relay boards are computer boards that contain a number of relays and switches. They are designed to control the voltage supply and have input and output terminals. Relay boards provide independently programmable, real-time control of multiple onboard relay channels
