PE2022A
GeNeral deSCriPtioN
The main function of the PE2022A circuit board is to:
■ manage the loads of the oven (contactors, motors (max 5 motors), solenoid valve, etc.)
■ read the measurements provided by the different sensors (temperature probes, door switch, etc.)
■ manage two Brahma TGRD61 gas control unit
■ manage 2 blowers for air-gas premix
■ power the low voltage of the entire system
■ communicate through CANBUS with the control board
■ communicate through (RS485) with possible bridge boards
