Compressor/Pump Relay: Description and Operation
The compressor relay is energized by the air suspension control module to allow high current to flow from the battery to the compressor motor.
-
A solid state relay is used in the air suspension system for air compressor control. The relay incorporates a custom power Metal Oxide
Semi-Conductor Field Effect Transistor (MOSFET) and ceramic hybrid circuitry. The relay switches high current loads in response to low power
signals and is controlled by the logic of the air suspension control module.
