What it does

The 4 Channel 5V Relay Module for Arduino, Raspberry Pi & Microcontrollers provides safe electrical isolation between low-voltage microcontroller circuits and high-voltage loads. It features 4-channel relay control with optocoupler isolation for reliable switching of AC and DC loads.

Key features

  • 4-channel relay for load switching
  • Optocoupler isolation between logic and load
  • LED indicators for status
  • 10A/250V AC or 10A/30V DC rating
  • 5V coil for easy control
  • Screw terminals for secure connections
  • Freewheeling diode protection

Good to know

  • HIGH VOLTAGE on relay contacts – handle with extreme care
  • Verify wiring before energizing
  • Mount in enclosure when controlling mains voltage
  • Relay coil draws ~70-90mA when energized
  • Inductive loads need snubber circuits
