Numatics ControlD
The Numatics ControlD is a stand-alone control device used for open-loop, closed-loop or dual-loop (cascaded) process control. It is designed to control proportional valves by regulating the current to the valve’s solenoid coil. Control loop parameters can be customized for an application using DigiCom software (included).
