Relay Selection

Relay selection lies at the heart of designing an effective and reliable Air Horn Wiring Diagram With Relay. Choosing the right relay ensures that the air horn system operates efficiently, safely, and sesuai with its intended purpose. Several key factors come into play when selecting a relay, each with its own implications on the system’s performance.

  • Voltage Compatibility: The relay’s coil voltage must match the voltage of the power source used to energize it. Common coil voltages for automotive relays range from 12V to 24V. Mismatched voltage can lead to relay failure or poor performance.
  • Current Rating: The relay’s contacts must be able to handle the current required by the air horn. The current rating is typically specified in amperes (A) and should exceed the maximum current draw of the air horn. Insufficient current rating can cause the relay contacts to overheat and fail.
  • Coil Resistance: The relay’s coil resistance affects the amount of current drawn by the coil. A higher coil resistance reduces current draw, which can be beneficial in applications where power consumption is a concern. However, a very high coil resistance can make the relay less sensitive to activation.
