SMIH-12VDC-SL-C 12V DC 8-Pin Sealed Power Relay – 16A

The SMIH-12VDC-SL-C Power Relay is a compact, sealed electromagnetic relay designed for switching electrical loads in automation, control circuits, and electronic equipment.

Featuring a 12V DC coil, 8-pin configuration, and a reported contact rating of up to 16A, this relay provides electrically isolated switching between a low-voltage control circuit and an external load.

Its fully enclosed construction helps protect the internal contacts from dust and environmental contaminants, making it suitable for PCB-based switching applications.

Key Features

  • 12V DC Coil: Designed for DC-powered relay control circuits.
  • High Switching Capacity: Reported contact rating of up to 16A.
  • 8-Pin Configuration: Suitable for compatible PCB mounting arrangements.
  • Sealed Housing: Helps protect internal components from dust and contamination.
  • Electromagnetic Switching: Allows a control circuit to operate an electrically isolated load.
  • Compact Design: Suitable for integration into electronic control boards.
  • SMIH Series: Power relay for electrical and automation applications.

Connection and Operation

The relay uses an electromagnetic coil to switch its contacts.

  1. Apply the specified 12V DC supply to the relay coil.
  2. The energized coil activates the internal switching mechanism.
  3. The relay contacts change state, controlling the connected load.
  4. 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.
