SICAM A8000 CP-8050, SICAM A8000 Rack, SICAM AK3

The SICAM A8000 CP-8050, the latest member of the SICAM A8000 family, is not only extremely compact but also extremely flexible and powerful thanks to its modern system architecture. The system offers a variety of possibilities to automate widely distributed processes. In terms of communication, automation functionality and redundancy, the SICAM A8000 CP-8050 is the most powerful device within the SICAM A8000 product family. Automation, telecontrol and communication tasks can be easily combined and are fully IEC 61850 compliant. Compared to its predecessor SICAM AK 3, it not only convinces with a much more compact mechanical design, but also with security features that are already deeply embedded in the system architecture. A significant simplification of the hardware components with a simultaneous increase in performance has also been achieved, details can be found in the “General" section.

Features & functions

SICAM A8000-CP8050: The processor board for optimized solutions for use in the higher performance range: The powerful dual-core CPU allows different communication protocols to be combined on one and the same interface.  Thus the need for hardware can be reduced significantly. A redundant power supply is just as much a part of the consistent further development as, for example, the redundancy function integrated deeper into the system, in order to significantly reduce engineering costs compared to its predecessor SICAM AK(3).

  • All existing and proven SICAM AK(3) system concepts or functions, starting with redundancy, automatic data flow, hardware-based application layer firewall, up to the support of pack-tight SICAM rack I/O boards and much more are of course still available with SICAM A8000 CP-8050 - as successor of the SICAM AK(3) generation.
  • The processor board SICAM A8000 CP-8050 offers 4 interfaces, which can be expanded with CI modules to a maximum of 34 units.
  • Universal binary or analog input/output modules can be plugged in any order and, with a module width of 30 mm, are suitable for even the smallest space conditions.

All functions can be used efficiently and easily with the new, intuitive engineering tool - the SICAM Device Manager. Furthermore, the system - like all products of the SICAM RTU system family - can also be parameterized with the object-oriented engineering software SICAM TOOLBOX II.


The SICAM A8000 CP-8050 is the first system ever to allow other applications besides the classic RTU functions to be loaded onto the same device. The proven docker container technology is used to protect the applications from each other. This allows the functionality to be expanded flexibly and customer-specifically without having to use additional hardware components. Find out more on our SIAPP page (


SICAM A8000 Rack Solution: The latest platform combines high packing density with a powerful CPU and latest cyber security standards.

  • For new systems with a high signal range at the smallest level.
  • As retrofit solution for further use of the AK / AK3 design without rewiring.

SICAM AK3: The new SICAM A8000 series replaces the proven SICAM AK system and offers the latest features also with regard to cyber security. Further information about SICAM AK3 is available in our partner portal SIOS.
