Extended mobile controller

The HCY is a universal control device for mobile hydraulic applications. It is based on the proven Völkel platform, which contains two decades' experience in control system engineering. Safety features and a CAN network make it possible to use the HCY control system in a versatile manner and for complex tasks. The controller is available with customer-specific software. The PC program ConDoc enables a rapid adaptation to the individual machine data as well as a comprehensive diagnosis. The HCY hardware is also available as programmable logic controller. In this way the advantages of a controller tested in rough environment complement with the benefits of free programming according to the international standard IEC 61131-3. Integrated current drivers for proportional solenoids, analog inputs, frequency and switch inputs effect quick programming.
