KY-019 5V 1-channel relay module high-level trigger

The 5V relay module is suitable for IOT projects with Arduino development boards.

Highlights

  • Operating voltage / TTL control signal: 5 V - 12 V 
  • One normally open (NO) and one normally closed (NC) contact
  • A power indicator LED
  • A control indicator LED, inactive when the relay is inactive

Important information

  • Please only use the relay for switching low voltages (i.e. below 12 V).
  • Working with higher voltages or mains voltage can lead to life-threatening injuries and is therefore reserved for trained specialists.
  • For the switching of higher voltages there are inexpensive and certified devices from leading providers in the smart home environment.
