Instructions for Use

1. Power Supply:

   • Ensure the coil voltage is 5V DC. Applying a higher voltage can damage the relay.

2. Installation:

   • Mount the relay on a PCB or a suitable mounting surface.
   • Ensure proper spacing to avoid interference with other components.

3. Wiring:

   • Connect the coil terminals to the control circuit.
   • Connect the common (COM), normally open (NO), and normally closed (NC) contacts to the load circuit as required.

4. Operation:

   • When the coil is energized, the common contact will switch from the NC to the NO position.
   • When the coil is de-energized, the common contact will return to the NC position.

5. Testing:

   • Use a multimeter to verify the continuity between the COM and NC contacts when the relay is de-energized.
   • Verify the continuity between the COM and NO contacts when the relay is energized.

6. Maintenance:

   • Regularly inspect the relay for signs of wear or damage.
   • Clean the relay contacts if necessary using a suitable contact cleaner.

7. Safety:

   • Ensure the relay is used within its specified operating parameters.
   • Do not exceed the maximum current ratings for the contacts.
   • Follow all local electrical codes and safety guidelines.
