PQ controls Model 504 Series Valve Drive Board
The Model 504 series of valve drive boards are an electronic interface between a command source (potentiometer, joystick, footpedal, etc.) and an electro-hydraulic valve or pump. The board recieves analog signals from the command source and provides Pulse Width Modulated (PWM) Output to drive most electrically modulated valves and pumps available today. The board also provides On/Off outputs and other features to smoothly stroke a valve or pump with greater control and flexibility over conventional hydraulic components. The 504 valve boards are designed for use on mobile equipment where extreme environments (both weather and electrical) are encountered.
