4-Relay 5v Module

This relay switch allows you to control up to 4 independent electronic devices with your microcontroller.

SPECS:

• Multiple Independent Channels: Each channel operates independently, allowing control of up to four different devices simultaneously.

  
  

• Low-voltage Control: The relay module allows for controlling high-power circuits with a low-voltage control signal, typically from a microcontroller or microprocessor.

  
  

• Optocoupler Isolation: Barrier between the low-voltage control circuit and the high-voltage load, protecting the microcontroller from potential damage due to electrical spikes.

  
  

• High Current Handling: The module can typically handle currents of up to 10A per channel.

  
  

• LED Indicators: If activated (ON) or deactivated (OFF).

  
  

• Simple Wiring: Marked pins for VCC, GND, and the control pins for each channel.
