The embedded PC is a passively cool­ed and very compact PC sys­tem that opens up many areas of app­li­ca­tion due to its num­er­ous inter­faces and in­te­gra­ted soft­ware tools

Key Features

  • Atom-CPU with passive cooling
  • Numerous interfaces like CAN, Ethernet, IOs, CFast, DVI and USB
  • Software tools for all tasks around the CAN bus
  • Link2Go: Extension modules can be attached without adapting the ePC like fieldbus couplers
  • IP20 full metal housing for optimum EMC protection


Key performance data
Various processors of the Atom series are avail­able. The chipset is characterized by high energy ef­fic­ien­cy and offers low heat loss. 1 to 2 GB RAM are available onboard and also enable more ex­ten­sive computing operations. The ePC has no rotating parts. Instead of a con­ven­tio­nal hard disk, the fast CFast is used as the suc­ces­sor to Compact Flash – the sys­tem can also be booted via this interface. The ad­van­tage is the speed of up to 3 Gbit/s for data transfer. All CFast cards from 4 to 32 GB are conveniently available from Sontheim.
Due to the full metal hous­ing, storage media and CPU, the system offers optimum EMC prop­er­ties and can be passive­ly cooled even under difficult en­vir­on­mental conditions.  

Link2Go – Put it on!
Modern automation applications require ef­fic­ien­cy and the flex­i­bil­ity to be able to react pre­cise­ly to changing requirements.


With Link2Go we have created the possibility to connect individual add-on modules to the ePC quickly and conveniently and to ex­change them as required. The spectrum of plan­ned mo­dules ran­ges from touch dis­plays and bus coup­lers to read-only memories and serial interfaces. Customer-specific modules can also be created. Link2Go – create your per­so­nal embedded solution at a standard com­po­nent price.

For maximum flexibility, the ePC already has nu­mer­ous inter­faces without extensions (Link2Go modules). These include CAN, Ether­net (EtherCAT-capable), digital inputs and outputs, DVI and USB. In the basic con­fi­gur­ation, tasks as PLC, CAN bus master or slave, signal processing center and many other applications are possible. The integrated CFast interface is – similar to a USB stick – suit­able for data collection and also for booting the device.
