Instructions for Use

1. Installation:

   • Ensure that the relay is mounted on a suitable PCB or chassis.
   • Verify that the mounting surface is clean and free from debris.

2. Wiring:

   • Connect the coil terminals to the appropriate power supply (5V, 12V, or 24V DC).
   • Connect the common (COM), normally open (NO), and normally closed (NC) terminals to the circuit as required.

3. Operation:

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

4. Testing:

   • Use a multimeter to verify the continuity between the COM and NC/NO contacts before and after energizing the coil.
   • Ensure that the relay operates within the specified temperature range.

5. Maintenance:

   • Regularly inspect the relay for signs of wear or damage.
   • Replace the relay if it fails to operate correctly or shows signs of physical damage.

6. Safety:

   • Do not exceed the maximum ratings for voltage and current.
   • Ensure proper insulation and isolation to prevent electrical shock.
   • Follow all relevant safety standards and guidelines.
