Instructions:

1. Installation:

   • Ensure the relay is mounted on a PCB with appropriate through-hole terminals.
   • Solder the relay terminals securely to the PCB.

2. Coil Connection:

   • Connect the coil terminals to the specified voltage (50VDC).
   • Ensure the current does not exceed 14.5mA to avoid overheating.

3. Contact Connection:

   • Connect the load to the normally open (NO) and common (COM) contacts for operation.
   • Connect the load to the normally closed (NC) and common (COM) contacts for de-energized state.

4. Operating Environment:

   • Operate the relay within the temperature range of -40°C to +85°C.
   • Store the relay within the temperature range of -40°C to +125°C.

5. Testing:

   • Test the relay by applying the specified coil voltage and verifying the contact operation.
   • Use a multimeter to check continuity between the NO and COM contacts when the coil is energized, and between the NC and COM contacts when the coil is de-energized.

6. Maintenance:

   • Regularly inspect the relay for signs of wear or damage.
   • Replace the relay if it fails to operate correctly or if the contacts show signs of excessive wear.

7. Safety:

   • Ensure the relay is disconnected from power before performing any maintenance or testing.
   • Follow all local electrical safety regulations and guidelines.
