The 1 Channel 5V Relay Module for Arduino, Raspberry Pi & Microcontrollers provides safe electrical isolation between low-voltage microcontroller circuits and high-voltage loads. It features 1-channel relay control with optocoupler isolation for reliable switching of AC and DC loads.
Key features
- 1-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
