Connection and Operation
The relay uses an electromagnetic coil to switch its contacts.
- Apply the specified 12V DC supply to the relay coil.
- The energized coil activates the internal switching mechanism.
- The relay contacts change state, controlling the connected load.
- When coil power is removed, the contacts return to their normal positions.
Important: Verify the exact coil terminals and contact pinout using the manufacturer's datasheet before wiring.
Applications
- Industrial Automation
- Electronic Control Boards
- Power Switching Circuits
- Home Automation Systems
- Electrical Control Equipment
- Motor Control Circuits
- Lighting Control
- Embedded Electronics Projects
- Relay-Based Switching Systems
Important Notes
-
The relay requires a 12V DC coil supply.
- A microcontroller GPIO cannot directly drive the relay coil; use a suitable transistor or relay driver circuit.
- Install a flyback diode or appropriate suppression circuit when using a DC relay coil.
- Verify the maximum contact current and voltage ratings before connecting a load.
- The original product information contains conflicting contact ratings and does not establish the exact contact configuration.
- Confirm the relay pinout and PCB footprint before installation.
- Disconnect power before installing or replacing the relay.
