Programmable digital hydraulic unit

From the union of hydraulic and digital electronics comes the Smart Power Unit Hydronit, the first compact programmable hydraulic power unit on the market. From the point of view of the range of hydraulic components, the SPUs share the same modularity concept (and most of the components) of the PPC series, thus offering the same flexibility.

Programmable digital hydraulic unit

The Smart Power Unit is the first generation of programmable digital hydraulic power unit available on the market. The heart of the Smart Power Unit is the HPC (Hydraulic Process Controller): a mechatronic module that integrates sensors, electronics and hydraulics in a single device, programmable with the CodesysTM IEC61131-3 automation software.

Hydronit has developed the Smart Power Unit, the first compact intelligent hydraulic power unit in the world.

FEATURES


The heart of the SPU is the HPC (Hydraulic Process Controller): a programmable controller with SAFETY Architecture. It integrates I / O, sensors, redundant double core processors with SAFETY and output power features to directly drive proportional solenoid valves or on-off valves without the need for external relays.


The hydraulic process controller is integrated in the hydraulic unit and available in different executions: proportional control of pressure [P], flow rate [Q] or P / Q with optional Load Sensing [LS] functionality.


HYDRAULIC INTEGRATION


HPC is seamlessly integrated with the standard Hydronit PPC compact power supply range as it uses the same standard PPC components.


Typical hydraulic circuits can be made with redundant valves in order to create SAFE (SIL2) applications ready for Industry 4.0 and Smart Manufacturing.

INTERNATIONAL AWARDS

Hydronit, in direct competition with the best European companies, has been awarded with multiple certificates of excellence from the European Commission during the Horizon 2020 framework program for research and innovation and, starting from July 2017, co-financed as a highly innovative.


The Smart Power Unit is patented n ° WO 2017/162298 A1.

INTEGRATED SENSORS


A high pressure ceramic pressure transducer (up to 350 bar), a crankshaft rotation speed sensor, two redundant 3-axis accelerometers and temperature sensors are integrated within the HPC. Additional external sensors can be connected via available I / O lines or fieldbus.

Questions and answers

  • How to customize the Smart Power Unit?

    The SPU is programmable, through the free graphic environment made available to CoDeSys, an IDE based on the international standard IEC-61131. It allows SPU programming using the most common languages used in industry: functional blocks (FDB), structured text (ST), Ladder (LD) and others.

  • What is the cost of the CoDeSys programming environment?

    The CoDeSys IDE is free for SPU customers.

  • Are displays and a control keyboard available?

    The graphic displays are customizable by Hydronit or by the customer himself according to his specifications. The keyboards are customizable through the use of plastic inserts available with more than 200 symbols. Both communicate with the SPU via the CAN bus.

  • Does Hydronit provide wiring?

    Connectors or simple harnesses are available as a standard offering. Customized wiring for the specific machine is available on request.

Application sectors

Hydronit compact power units are used where space limits make it difficult to install a traditional centralized hydraulic unit, such as in vehicles, boats, small industrial machines. Distributed hydraulics, installed close to the actuator, enables cost and installation savings and offers redundancy in the event of a failure.
