The 5V 2 Channel Relay Module<\/strong> is a compact and reliable relay interface board used to control electrical devices with microcontrollers and embedded systems. It contains two independent 5V electromagnetic relays<\/strong> that can be controlled through digital input signals from Arduino, ESP modules, PIC, AVR, and other development boards.<\/p>\n

This relay module provides electrical isolation between the control circuit and the high-power load circuit, making it suitable for switching lamps, motors, fans, pumps, solenoid valves, and other electrical appliances.<\/p>\n

The module includes onboard transistor driver circuits, protection diodes, indicator LEDs, and relay switching terminals, eliminating the need for additional driver components. Each relay channel can be controlled separately through input pins.<\/p>\n

The 5V 2 Channel Relay Module<\/strong> is widely used in automation, IoT projects, smart home systems, robotics, industrial control projects, and DIY electronics applications.<\/p>\n
