Scalable intelligence in a low-power rugged form factor

April 04, 2017 // By Julien Happich
Aitech Defense Systems has developed a new method of providing high performance, application-specific remote I/O management through the use of expansion modules, or “slices,” in the new rugged, space-qualified Ai-RIO.

 Through its modular, small form-factor (SFF) structure, the remote I/O interface unit (RIU) is a system-of-systems that provides a new level of scalable intelligence that meets specific user requirements and adapts to evolving application needs.

The Ai-RIO is an extremely high density, low power rugged sub-system that provides exceptional, user-specific functionality. The Ai-RIO is easy to expand, with up to eight units networked together, for unprecedented functionality in a compact space.  Added capabilities include I/O, power switching, mass/SD FLASH memory as well as other functionalities. Offering one of the widest ranges of I/O available in a SFF platform, the remote I/O sub-system includes a Gb Ethernet port with precision time sync IEEE-1588 support, ten RS-422 ports (eight of which are RS-422/485), an additional eight LVDS or RS-422/485 UARTS as well as four SpaceWire ports with LVDS I/O, two CANbus ports and sixteen GPIO in two blocks of eight. Using Aitech’s RIO-NET client/server software as well as additional memory and I/O arrays, the new unit can serve as a standalone command and data handling (C&DH) platform or networked remote command/response I/O unit. The rugged Ai-RIO features a powerful radiation-qualified, dual-core PowerPC processor with two rad-tolerant FPGAs.  All internal electronics are conduction-cooled and mechanically fixed and housed within a sealed, EMI/EMC Faraday cage for maximum thermal transfer. The housing is constructed of 6061/T6 flight grade aluminium and is based on a common 5.5"x5.5"x1.2" form factor. External connectors can be either micro D-Subs for space applications or standard micro MIL-DTL-38999 circular military connectors for use in defence environments.  The base unit configuration weight of an Ai-RIO is only 3.75 lbs with a power dissipation of less than 12W.
