Approximately 9V (the voltage at which the relay activates).
Typically connected to the ground (negative terminal of the battery). shema podkljuchenija rs527
In a standard cooling fan or headlight setup, the relay acts as an intermediary. Without it, the heavy current required by the fan would melt the dash switch. By using the RS527: The sends a tiny current to Pin 86 . The Coil inside creates a magnetic field. Approximately 9V (the voltage at which the relay activates)
Ensure the motor or component being powered is grounded correctly to prevent fire hazards or electrocution. Without it, the heavy current required by the
Use appropriate wire thickness (e.g., 12 AWG or 14 AWG) for the high-current path (Pins 30 and 87) to prevent overheating.
These pins are connected to the relay's internal electromagnetic coil.
The snap shut, bridging Pin 30 and Pin 87 . The Load (Fan/Lights) receives full battery power safely. Safety and Installation Tips
