Control Board
The control board is used to control the turning on and turning off of the motor and solenoid valve.
The main board issues a start signal and a low voltage signal (12V) for opening the electromagnetic valve, which are converted into strong voltage signals (220VAC) to drive the electromagnetic valve (380VAC) and the motor in our fuel dispensers system, thus completing the function of conversion from weak voltage power to stong voltage power. The control board circuit isolates high voltage interference signals via photoelectrical isolating components.
