What does decentralised automation actually mean?

With decentralised solutions, control and monitoring take place directly in the field,exactly where the action takes place. Individual valves, remote I/O modules and valve terminals are mounted close to the process. This reduces cable lengths and increases the reaction speed.

Decentralised automation solutions have been tried and tested for many systems in hydrogen production. Festo supplies ready-to-install, sturdy and space-saving solutions that are installed directly in the field. This ensures efficient and safe operation, even when space is limited. For more complex systems, demanding safety requirements or highly standardised processes, central control cabinet concepts can offer additional advantages in terms of integration, documentation and easier maintenance. Depending on the specific requirements, a combination of decentralised and centralised components can also be the most flexible solution.

How Festo supports your hydrogen production

In our expert video "From the control level to the field level – automation solutions for hydrogen production", Reiner Laun, Hydrogen Global Industry Segment Manager at Festo, explains how decentralised automation benefits customers.

Examples of decentralised automation products

  • CPX platform – modularly expandable valve terminal, open for various protocols
  • Remote I/O modules for analogue and digital signals
  • Individual valves directly on the actuator
  • Ball valve units for oxygen and hydrogen
  • Angle seat valves for precise closed-loop control
  • Components for explosion proof areas (ATEX-certified)

Safe hydrogen despite explosion risk

Hydrogen is highly reactive. That is why decentralised automation must be safe and reliable,in potentially explosive areas too. Festo offers specially certified components for Ex zones as well as solutions for non-explosion-proof environments. For maximum safety during electrolysis.

Isn't that too time-consuming? – Quite the opposite.

A decentralised system may seem complex, but it is often simpler in everyday operation. It has clearly structured modules, is easy to expand, and the direct access to field devices makes maintenance and disassembly easier. Festo supplies pre-configured, tested solutions on request – ready for immediate use.

Everything from a single source

Festo offers you an personalised and coordinated product portfolio for decentralised automation. Working with just one partner has many advantages: You reduce the number of suppliers, lower your planning, procurement and operation costs and have a contact person who knows you.

A clever alternative: the control cabinet

We show why centralised control with a control cabinet can also be a great solution. Because a control cabinet brings all the important components together: the control unit, valve terminals and compressed air preparation are located in a "control centre". This creates order and reliably protects the technology – for example the pneumatic, electric and electronic components in the electrolyser – and simplifies installation.
