NAI Introduces Industry's First Nano-sized Intelligent I/O(TM) Communications Subsystem

NIU1 Provides I/O and Communications Functions without costly NRE— in a self-contained compact solution

Bohemia, NY -- North Atlantic Industries (NAI) announces the availability of the Industry’s first integrated, compact, nano-sized subsystem with unprecedented I/O capabilities that connects to existing platform Ethernet networks, making data available to any system on the network. The Nano Interface Unit (NIU1) easily adds sensor data acquisition, distribution and communication interfaces to mission computers without expensive chassis and backplane redesign, for use in military and aerospace embedded applications.

Leveraging NAI’s field-proven, unique modular architecture, the NIU1 supports a wide selection of different Intelligent I/O, motion simulation/measurement and communications functions such as: A/D, D/A, TTL, RTD; Discrete I/O; Differential Transceiver, Synchro/Resolver/LVDT/RVDT Measurement, Simulation and Excitation; Strain Gage; Encoder; Dual Channel Dual Redundant BC/RT/MT MIL-STD-1553; high speed Sync/Async RS232/422/423/485; ARINC 429/575 and CANBus. This approach provides a simple integration effort for dedicated I/O interface capability to existing or new applications, targeting specific interfacing requirements and provides a complete I/O function subsystem. In addition, Power-over-Ethernet (PoE) is standard on the NIU1 making it easy to integrate where 28 Vdc power isn’t readily available.

Significant application benefits include:

• Independent (pre-processed) I/O functionality targeted to specific data acquisition/control areas

• Additional capabilities, technology insertion and sensor interfacing to existing fielded applications

• Minimal integration risk based on current field-proven, deployed technologies

• Only 1.5”H x 1.6”D x 6.5”L @ 16 oz. (454 g) with three mounting options.

“Our customers demand innovation in our Intelligent I/O products and the NIU1 brings immediate single function I/O and communication capability in a small, versatile and rugged subsystem,” explains Lino Massafra, VP of Sales/Marketing. “NIU1 delivers Intelligent I/O and communications where systems engineers need it.”

Pricing in quantity 100 of the NIU1-P8 configured with four high speed Sync/Async RS232/422/423/485 serial ports, 28Vdc input, Power-over-Ethernet and Dual Gigabit Ethernet Ports starts at $2,568 each. Delivery starts at 10 weeks, ARO.
