PE2021C GENERAL DESCRIPTION
The PE2021C is a circuit board with its main functions being to:
■ manage the loads of the oven (contactors, motors, solenoid valve, etc.)
■ read the measurements provided by the different sensors (temperature probes, door switch, etc.)
■ power the low voltage of the entire system
■ communicate through CANBUS with the control board
■ communicate through (RS485) with possible bridge boards
