Relay Module 5V 2 Channel

Description:

• It's an interface board containing two electromagnetic relays.   
• These relays act as electrically controlled switches, enabling the control of high-voltage or high-current devices.   
• The 5V designation indicates the voltage required to activate the relays.  
• The "2-channel" aspect signifies that the module can control two separate circuits.

Key Features:

• Electrical Isolation: Relays provide electrical isolation between the low-power control circuit and the high-power load circuit, enhancing safety.  
• High Current/Voltage Switching: Capable of switching AC and DC loads, typically up to 10A at 250VAC or 30VDC.   
• Microcontroller Compatibility: Designed to interface with 5V logic levels from microcontrollers (Arduino, etc.).   
• Screw Terminals: Provides convenient screw terminals for easy and secure wiring of load circuits.   
• LED Indicators: Often includes LEDs that indicate the relay's on/off status.   
• Protection Circuitry: Many modules have flyback diodes to protect the control circuitry from voltage spikes.
• Optocoupler inclusion: many modules include optocouplers, to further isolate the controlling circuit from the load circuit.   

Applications:

• Home Automation: Controlling lights, fans, and other appliances.   
• Robotics: Switching motors, solenoids, and other actuators.
• Industrial Control: Automating processes and controlling machinery.   
• Automotive Electronics: Controlling vehicle accessories.
• DIY Electronics Projects: Any project requiring the switching of high-power loads.
