The C2 proportional system controller works with high-speed, high-accuracy proportional pneumatic valves. The device can control nonpneumatic devices such as voice-coil actuators and linear electric drives, or as a stand-alone advanced PID controller for test and measurement or R&D applications.
A backlit graphic LCD and membrane keypad access intuitive menus to configure and tune the system. Closed-loop control electronics use a flexible PID+FF scheme with valve-management circuitry that includes a dead-band eliminator. Configuration settings include independent scaling of command and feedback signals; command ramp rates; electronic valve offset; and the ability to save and recall up to 10 gain configurations. The unit is available with or without a built-in valve driver.
