The SIU34, or Sensor Interface Unit, is a rugged, conduction-cooled chassis designed for demanding embedded system applications. Here are the detailed specifications and capabilities:

Rugged Design:

Base-plate conduction-cooled chassis suitable for harsh environments. Designed to house up to four multi-function pre-configurable Single Board Computer (SBC) and I/O boards. Modular and Configurable:

Supports NAI’s Configurable Open Systems Architecture™ (COSA®). Can integrate a variety of interface and communications modules including MIL-STD-1553, ARINC 429/575, Serial, ARINC 825 CAN bus among others. PowerPC, Intel®, or ARM SBC processors can be added for a comprehensive processing and I/O solution. Communication and I/O:

Provides full I/O control and communication over Ethernet with support for board-level processing. Varied primary communications interfaces depending on board configurations. Power Supply:

Comes with a single mil-standard power supply unit, with an additional option for “hold-up” power/time. Applications and Use Cases:

Ideal for high-density I/O, communications, Ethernet switching, and processing for Mil-Aero applications. Versatile for applications such as data acquisition (DAQ), fire control, and other mission-critical tasks. System Configurations:

Can function as either a centralized or distributed system. Can be used to enhance legacy systems by adding sensor data acquisition and general I/O and communication interfaces without extensive redesign.
