DAMA 4 Pin Multi Purpose 30/20A Heavy Duty SPST Relay | Pack of 1

DAMA 4 Pin Multi Purpose 30/20A Heavy Duty SPST Relay can be used in various applications. This relay is used for high powered retrofitted headlights or fog light systems but is also widely used for upgrading car motors, fuel pumps, fog horns, trunk solenoids, and cooling fans.

A 4 Pin 12V 120/200A Split Charge SPST Relay is typically used in automotive and marine applications to manage the charging of multiple batteries in a vehicle or vessel. The primary purpose of a split charge relay is to isolate the starter battery from auxiliary batteries when the engine is not running, preventing the auxiliary batteries from draining the starter battery.

Here are common applications for a 4 Pin 12V 120/200A Split Charge SPST Relay:

  1. Dual Battery Systems:

    • In vehicles with dual battery setups, such as RVs, boats, off-road vehicles, and camper vans, the relay is used to connect the auxiliary (house) battery to the charging system only when the engine is running. This ensures that the starter battery is prioritized during engine start.
  2. Camper Vans and RVs:

    • When converting a van into a camper or RV, a split charge relay is often employed to charge the house battery from the vehicle's alternator while driving. This allows appliances in the camper to be powered without draining the vehicle's starter battery.
  3. Marine Applications:

    • Boats with multiple battery banks for various systems (e.g., engine, navigation, accessories) use split charge relays to manage the charging process and prevent discharging of critical batteries.
  4. Off-Road Vehicles:

    • Off-road vehicles equipped with additional lighting, winches, or other accessories can benefit from a split charge relay to isolate and protect the primary battery while ensuring the auxiliary battery is charged when needed.
  5. Emergency Vehicles:

    • Emergency service vehicles, such as ambulances or fire trucks, may utilize split charge relays to maintain a separate power source for auxiliary equipment without compromising the starting power of the vehicle.

Key Components of a 4 Pin 12V 120/200A Split Charge SPST Relay:

  • SPST (Single Pole Single Throw): The relay has one normally open contact, allowing current flow when activated.
  • 4 Pins: Typically labeled as Normally Open (NO), Normally Closed (NC), Common (C), and Coil (or Control).
  • 12V: Designed to operate with a 12-volt electrical system.
  • 120/200A: Indicates the maximum current capacity of the relay, which is crucial for handling the charging current between batteries.

Always refer to the specific relay's datasheet or instructions to ensure proper installation and usage in your particular vehicle or application.
