The great variety of interfaces like LAN, CF, USB, I²C, serial interface, CAN interface, digital I/O makes it easy to connect various industrial devices to the OpenRISC. Because of CAN and RS485 options the Alena is good in monitoring field bus systems. Compact dimensions and DIN Rail mounting capability make the OpenRISC to a space saving and flexible mounting industrial computer. It is feasible to be installed even in space limited environments. The internal microSD slot protects the system software against accidentally removal. Due to RISC based architecture the OpenRISC has very small power consumption, so fanless heat dissipation is possible. Working in a wide temperature range from -10°C up to 65°C the OpenRISC can be applied in under harsh industrial conditions. Therefore the OpenRISC is downright designed for industrial automation. The embedded computer runs full-featured Debian GNU/Linux on ARM operating system Kernel 2.6. With Debian's repository database it is easy to install and update the free software on the OpenRISC. The OpenRISC is capable to act directly as software development host, WEB, Mail, Print and Database server or as a desktop computer with X11 window manager and many more.
