1 CHANNEL 12V RELAY MODULE

The 1-Channel 12V Relay Module is a single-channel electromagnetic relay module designed to control high-voltage or high-current AC/DC loads using low-voltage control signals from a microcontroller. It operates with a 12 V relay coil and can switch AC loads up to 250 V and DC loads up to 30 V, depending on the relay specifications. The module typically includes optocoupler isolation, transistor driver circuitry, flyback diode protection, and status LED indicators, ensuring safe, reliable, and stable operation. It can be easily interfaced with Arduino, ESP32, STM32, Raspberry Pi, and PIC microcontrollers through a digital output pin. Due to its compact design, electrical isolation, and dependable performance, the 1-Channel 12V Relay Module is widely used in home automation, industrial automation, IoT devices, robotics, lighting control, motor switching, security systems, and remote control applications.
