DSM Computer extends its product range with an easily installable, compact standard DIN rail-mounted PC family

Thanks to its standardized installation capability, the industrial computer with a width of only 7 MW (122 mm) can be easily installed in a switchgear cabinet or standard electrical cabinet. DSM's new standard DIN rail-mounted family can be deployed as a gateway and communications computer, Web server or distributed control unit in the industrial environment, e.g. in the building automation, in smart metering and electro-mobility applications, in plant control and in cloud computing solutions.

The core component of the H1-A standard DIN rail-mounted PC is a small Qseven™ module sized only 70 x 70 mm from MSC Vertriebs GmbH that is based on the energy-saving Intel® Atom™ processor Z510. The module is currently available in two variants, with 1 GB DDR2 memory and 2 GB flash memory, or as an alternative with 512 MB RAM without flash memory. The Intel® US15W SCH System Controller Hub with integrated Intel® Graphics Media Accelerator GMA 500 is deployed as chipset. To achieve an optimum heat dissipation, the Qseven™ board is directly connected with the computer housing.

In addition to the two fast GigaBit LAN and two USB 2.0 outputs, the H1-A provides a serial RS232 connection; if required, a second RS232 interface can be provided instead of the usual VGA interface. To compensate for potential differences, the two RS485 ports are galvanically isolated. This allows distances as long as 1000 meters to be bridged. The VGA interface can be used to connect a control monitor for the commissioning and for maintenance purposes. The user data can be saved on the onboard flash memory or on an SD card. System monitoring, a watchdog timer and the ACPI power management ensure the high reliability of the computer.

The standard DIN rail-mounted PC is installed in a robust, high-quality aluminum housing with a height of 90 mm and a depth of 41 mm (55 mm with cooling fins). The 24 V DC power supply and the RS485 interfaces are implemented as screwed- or clamp-type contact. The specified operating temperature range of the industrial PC lies between 0° and 45° C.
