Detailed Product Description:

Unlock the potential of your Arduino projects with a versatile 5V 1 Channel Relay Module, the essential component for safely controlling higher voltage or current loads using low-power microcontroller signals. This single channel relay module 5V acts as an electrically operated switch, providing crucial isolation between your sensitive Arduino circuitry and the connected load. Designed for seamless integration, our Arduino compatible relay modules feature a nominal coil voltage of 5V DC, directly compatible with Arduino's digital output pins.

At its core, an electromechanical relay operates on the principle of an electromagnet. When a 5V logic HIGH or LOW signal (depending on the module's trigger type, typically active-low for common Arduino modules) is applied to the control input, current flows through the relay's coil, generating a magnetic field. This field actuates an armature, causing a mechanical switch to change its state. The module typically provides three terminals for the load: Normally Open (NO), Normally Closed (NC), and Common (COM). In its de-energized state, the COM terminal is connected to NC. Upon activation, COM switches its connection to NO, allowing you to selectively power or depower external devices.

Our 5V 1 Channel Relay Module boasts a robust switching capacity, commonly rated at up to 10A for both 250VAC and 30VDC, making it suitable for a diverse range of applications from home automation (controlling lights, fans, or appliances) to high current switching in robotics and industrial control. Many modules incorporate a transistor driver for efficient coil activation and a flyback diode to suppress inductive voltage spikes, protecting your microcontroller. Indicator LEDs often provide visual feedback on the module's power status and the relay's current state. If you're looking to buy 5V 1 channel relay modules at a competitive 5V relay module price, explore our selection. These modules are indispensable for safely interfacing your Arduino with devices that demand power beyond the microcontroller's direct output capabilities.

The 5V Single Channel Relay Module is a compact and reliable switching board that allows microcontrollers or digital systems to control high-voltage AC or DC loads. Featuring a mechanical relay switch, optocoupler isolation, and onboard status indicators, this module ensures safe and effective switching of fans, lights, motors, or other devices.
