Application Ready Systems

The need to quickly communicate actionable information between the command center and manned and unmanned military vehicles in the air, on land and at sea is of critical importance in all levels of warfare today.

Data Acquisition (DAQ) systems are used to collect information for the purpose of documenting or analyzing an electrical or physical phenomenon, for example: temperature or pressure. They serve as a focal point in tying a wide variety of sensors together that indicate temperature, flow, level or pressure. The sensors convert a physical occurrence into a measurable electrical signal, which can be factored into command and control decisions. These high-speed DAQ systems feature different analog and digital input and output modules that can be used with a wide range of signal types including 4-20 mA current, thermocouples, and RTDs.

DAQ systems are typically comprised of a chassis, backplane controller and customer-selected modules. Embedded DAQ systems have the ability to combine the I/O subsystem and mission computer into one package. Communications-based DAQs interface with a computer through a communications port and can act as remote, intelligent control systems. Serial communications such as RS-232 and -485 provide the ability to communicate long distances with multiple units on the line.

Additionally, these rugged systems must meet stringent environmental requirements such as shock, vibration and extreme temperatures within SWaP-constrained environments. These attributes are inherent in most COTS designs and offer customers readily-available, interoperable, field-proven systems and subsystems out of the box.

NAI leverages its decades of experience in embedding electronics to include application-ready Data Acquisition systems. With our highly adaptive, modular Configurable Open Systems Architecture™ (COSA®), NAI's I/O boards have the highest packaging density and greatest flexibility of any multifunction I/O boards in the industry, delivering more intelligence and functionality in a smaller footprint— all at a lower cost and shorter lead time.

NAI’s rugged DAQ systems offer a proven solution for acquiring information in real time and are ruggedized to withstand -40º C to +71º C and qualified to MIL-STD-1275D & MIL-STD-704A with 50 ms holdup (power supply); MIL-STD-461F and MIL-STD-810G.

Accelerate Your Time-to-Mission™ with NAI.
