The Kontron ThinkIO-Duo (70mm deep / 35mm slot level) is equipped with an Intel Core Duo U2500 processor with a clock rate of 2 x 1.2 GHz and 512MB or 1GB of RAM. Along with internal Flash (512MB/2GB), this passively-cooled PC, also offers a customizable CompactFlash socket for data storage or backups/updates, 512KB non-volatile memory and all the standard PC interfaces (2 x USB 2.0, RS232, DVI-I). Three LAN interfaces make it possible to connect a variety of media such as cameras or a WLAN router. Users can also implement an Ethernet-based 'software' field bus. In addition, remote access/monitoring and control or connection to the company's MES or ERP systems and databases are possible.

There are also interrupt-capable onboard inputs which can be used for rapid reaction to extreme events, such as activating a cut-off switch. Watchdog and real-time clock round out the system's features.

Similar to all of the Kontron ThinkIO family, the option is available for the Wago 750/753 I/O clamps to be connected directly.

The Kontron ThinkIO-Duo is available with Windows XP Embedded Embedded or a Linux OSADL software package (Open Source Automaton Development Lab). The Dual-core technology used with Linux or Windows XPe makes Symmetric Multi-Processing (SMP) possible. Another component of dual core technology is Intel Virtualization Technology, which makes hardware administration even simpler.
