Instructions for Use:

1. Installation:

   • Ensure the relay is mounted on a suitable PCB or chassis.
   • Secure the relay using the provided mounting holes to prevent mechanical stress.

2. Wiring:

   • Connect the coil terminals to the appropriate power supply (5V DC).
   • Connect the common (COM), normally open (NO), and normally closed (NC) contacts to the circuit you wish to control.

3. 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.

4. Handling:

   • Handle the relay with care to avoid damaging the contacts or the coil.
   • Avoid exposing the relay to excessive humidity, dust, or corrosive environments.

5. Testing:

   • Use a multimeter to verify the continuity between the contacts before and after energizing the coil.
   • Check the coil resistance to ensure it matches the specified value.

6. Maintenance:

   • Regularly inspect the relay for signs of wear or damage.
   • Replace the relay if any issues are detected to ensure reliable operation.
