Instructions for Use:

1. Installation:

   • Ensure that the relay is installed in a location where it will not be exposed to excessive heat, moisture, or mechanical stress.
   • Mount the relay on a flat, stable surface using the provided mounting holes.

2. Wiring:

   • Connect the coil terminals to the control circuit using the specified coil voltage (12V DC).
   • Connect the common (C), normally open (NO), and normally closed (NC) terminals to the load circuit according to your application requirements.

3. Operation:

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

4. Testing:

   • Test the relay by applying the specified coil voltage and verifying that the contacts switch as expected.
   • Measure the contact resistance to ensure it is within the specified range.

5. Maintenance:

   • Regularly inspect the relay for signs of wear or damage.
   • If the relay fails to operate correctly, check the wiring and power supply before replacing the relay.

6. Safety:

   • Do not exceed the maximum switching voltage and current ratings.
   • Ensure that the relay is disconnected from the power source before performing any maintenance or testing.
