The HCY is a universal control device for mobile hydraulic applications. It is based on the proven Völkel platform, which contains two decades of 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 user can adopt the HCY to the requested control functions by software, supported by the PC software tool ConDoc.
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, analogue inputs, frequency and switch inputs effect quick programming.
