Description: 1. The 2 CH 12V Relay Board is a versatile IoT component designed to operate two independent 12V relays with opto-isolated inputs for enhanced safety and reliability. 2. Features: This board comes with two opto-isolated relay channels, each capable of handling a maximum load of 30A at 12V DC. It also includes LED indicator lights for status monitoring and diode protection to prevent back EMF damage. 3. Use Cases: Common applications include controlling heavy electrical loads (e.g., pumps, compressors, solenoids) in IoT projects or automation systems via digital signals from a microcontroller or computer. 4. Easy Integration: The 2 CH 12V Relay Board can be easily integrated with various control systems and programming languages (Arduino, Raspberry Pi, Python, etc.) using simple wiring and minimal configuration. 5. Reliability: By implementing opto-isolation, the board ensures a strong electrical barrier between the input and output sides, reducing potential hazards such as short c
