BL02-0AA0 Double Proportional board IS SUITABLE TO AUTOMATIC BLOW MOULDING MACHINE ; The proportional valve amplifier board amplifies the weak signal (current or voltage) reflected in the control process to drive the proportional valve parameters to change proportioned to achieve the purpose of automatic control. Proportional amplifier board mainly through the size of the current to change the driving pressure. It is best to use high precision, and current control proportional valve; In this way, the function of the magnifying plate can be best played.
