The Model SBF90 flasher/controller is a completely electronic microprocessor based device dedicated to the school bus warning light application. It is comprised of a logic controller and a unique and highly efficient power switching circuit. The SBF90 operates the stop arm solenoid and eight 80 watt warning lamps. Inputs from the Start Switch and Passenger Door Switch activate the flasher/controller. Master Switch and Override Switch provisions are also included. Capabilities for both Sequential and Non-Sequential operation are provided.
The Model SBF90 flasher's circuitry is sealed to protect against severe environments and its internal construction is designed to withstand shock and vibration typically found in school bus applications. Wiring connections to the unit are via industry standard 0.25 inch Faston terminals.
