An international military customer needed multiple communication interfaces for its helicopter, as well as a method to process many channels of various analog and digital signals. A rugged, conduction-cooled, self-contained system that could be networked to other systems on the helicopter was required. The SIU6 provided an excellent solution with a local PowerPC processor and over 100 channels of various intelligent, Multifunction I/O. In addition, the SIU6 met all demanding environmental and EMI requirements. This fully integrated and tested network solution enabled the customer to interface and process all I/O signals in a SWaP-efficient box using COTS components.
