requirements are high and frequently specific, yet the development and manufacturing costs must be as low as possible, especially for low quantities. This balancing act is best addressed with a standard modular series that already meets many of the requirements. Polyrack designed its PanelPC2 series specifically for industrial applications. It encompasses different display sizes and technologies, case materials and

additional features. Thus, the supplier can implement customer-specific solutions in terms of a design-to-cost development. Regarding the integration stage, the customer can have everything right up to a computer that has been inspected and is immediately ready for use. Long development times and lifetime of applications are supported with long- term availability of components and systems .


ININ I INDUS NDUSTRY In machine control, easy-to-use


operating interfaces are desired not only by the users; they are also required to control increasingly complex machines. For use in harsh, industrial environments Panel PCs must be highly robust and resistant to shock and vibration, dust, dirt and moisture.


If the Panel PC is integrated into the machine, the dimensionsmustmeet fixed specifications. This can be best


accomplished even with low quantities with a casemade ofmilled aluminium. Plate-bending or tool-dependent solutions enable lower costs for higher quantities. If the Panel PC needs to be attached to themachine, flexiblemounts compensate themovement of themachine and protect the sensitive electronics. In addition to beingmounted on a supporting arm, Panel PCs can also bemounted on the wall or i n a control cabine t.


If a high-performance computer


platform or other active components are to be integrated, a well-thought-out cooling concept will be needed. This must be designed into the product at an early stage. To dimension this, Polyrack uses thermosimulation. The PanelPC 2

If the user terminals are outdoors they are also exposed to changing weather conditions. Therefore, the Panel PCs should be designed for a wide


temperature range of -20° to 85°C. Modern gasket systems protect the devices against rainwater ingress and high humidity. Than

In public areas, design and surface feel also play an important role. These enhance the ease of passengers; informa


tion systems in eye- use for the


series is by default cooled passively by way of the rear hood, as this solution functions reliably in harsh environments. It can be adapted to the TDP of the platform used by means of a cooling-fin or heatsink construction with a heat pipe connection. If the cooling thus achieved is not adequate or not possible, cooling can be performed actively.


RAILWAY ECHNOLOG APPLICATIONS On display terminals or ticket machines in train and subway stations, front protection with protection class IP67 is particularly important. A surface made of toughened, scratch-proof glass with a special anti-fingerprint coating ensures, that the displays remain scratch-free and can be used long term. The danger of vandalism can be counteracted with double-walled cases and systems of variable sandwich construction, in which the display and the case can be assembled layer by layer.

catching colours are easier to find. Depending on the case material. The company offers a selection of different coatings, laser engraving, printing and varnishes, including UV- proof and anti-graffiti paints. Many surface treatments thus enhance not only the visual appearance but also th e robustness and ensure that any lettering remains legible in the long-term. In trains, Panel PCs are used for the passenger entertainment system as well as the control unit for the guard. Here they have to withstand high mechanical stress. With speeds of up to 300 kilometers per hour, secure mounting and vibration resistance of 5 to 25 g are required. In addition to this there are the EMC requirements, statutory directive s and fire protection instructions as well as any standards specified by the vehicle manufacturer.
