Instructions:

1. Installation:

   • Ensure the power supply is turned off before installation.
   • Align the pins of the PCJ-112D3M with the corresponding holes on the PCB.
   • Gently press the relay into place until it clicks.

2. Wiring:

   • Connect the common (COM) terminal to the load or power source.
   • Connect the normally open (NO) terminal to the controlled circuit.
   • Connect the normally closed (NC) terminal if needed.
   • Connect the coil terminals to the control circuit, ensuring the correct polarity (12V).

3. Testing:

   • Apply 12V to the coil terminals to energize the relay.
   • Verify that the NO contact closes and the NC contact opens.
   • Measure the contact resistance to ensure it is within the specified range.

4. Maintenance:

   • Regularly inspect the relay for signs of wear or damage.
   • Clean the contacts with a soft, dry cloth if necessary.
   • Replace the relay if it fails to operate correctly or shows signs of excessive wear.

5. Storage:

   • Store the relay in a dry, cool place away from direct sunlight and corrosive materials.
   • Avoid exposure to extreme temperatures and high humidity.

6. Safety Precautions:

   • Do not exceed the rated voltage and current.
   • Use appropriate fuses and circuit breakers to protect the relay.
   • Follow all local electrical codes and regulations.
