The 10 Channel 12V Relay Module is a high-performance switching board designed for projects that require greater power stability and load handling. With 10 independent relays, it allows microcontrollers like Arduino, Raspberry Pi, and PIC to control fans, pumps, lights, motors, and other high-voltage devices safely. The 12V power input provides extra reliability in industrial environments, ensuring steady operation even under heavy loads. This module is widely used in home automation, IoT projects, robotics, and industrial machinery control systems in Bangladesh. Featuring LED indicators and optocoupler isolation, it offers both safety and convenience for makers, students, and engineers.
