Product Details
5V 10A Relay Switch Module – Single Channel Electromagnetic Relay
The 5V 10A Relay Switch Module is a compact, single-channel electromagnetic relay breakout board designed to let low-power microcontrollers safely switch high-voltage and high-current AC or DC loads. Unlike transistors that are limited by maximum collector current and cannot handle AC loads, this relay module can switch loads up to 250V AC or 30V DC at currents up to 10A — all triggered from a simple 5V GPIO signal drawing only 20mA.
The module is built around a standard electromagnetic relay with clearly labelled COM (Common), NO (Normally Open), and NC (Normally Closed) screw terminals, giving full flexibility to either connect or disconnect a load when the relay is activated. An onboard status indicator LED provides immediate visual feedback of the relay's current state, making debugging and prototyping fast and effortless.
To operate: power the module via its Vcc (5V) and GND pins, then connect the IN (Control) pin to any GPIO pin of a 5V microcontroller such as Arduino UNO or MEGA. Drive the control pin HIGH or LOW via your program to switch the relay ON or OFF. The load is connected across the COM and NO terminals (to energize on trigger) or COM and NC terminals (to de-energize on trigger), depending on the application logic.
