Six New Low-Cost Digital I/O Devices from NI Deliver High-Reliability Industrial Feature Set for Real-Time Applications.

Business Editors/High-Tech Writers

AUSTIN, Texas--(BUSINESS WIRE)--May 25, 2004

National Instruments (Nasdaq:NATI) today announced six new low-cost, optically isolated digital I/O devices that deliver a high-reliability industrial feature set for applications in discrete, batch and process automation. Each device offers industrial features such as watchdog timers, optical isolation, 24 V logic levels, programmable power-up states, programmable input filters, change detection and industrial certifications.

Starting at $345 or $5 per I/O channel, the NI 651x family of DIO devices includes:

-- NI PCI-6511 and NI PXI/CompactPCI 6511 - +/-30 VDC, optically

isolated industrial 64 digital input, sinking/sourcing

-- NI PCI-6512 and NI PXI/CompactPCI 6512 - +/-30 VDC, optically

isolated industrial 64 digital output, sourcing, 350 mA max

current drive

-- NI PCI-6513 and NI PXI/CompactPCI 6513 - +/-30 VDC, optically

isolated industrial 64 digital output, sinking, 475 mA max

current drive

The 24 V logic levels included in these devices offers direct connection to industrial sensors and actuators, and are completely software programmable without jumpers. Engineers can use programmable power-up states to configure the initial digital state in software and ensure safe operation when controlling industrial actuators such as pumps, valves, motors and relays. Programmable input filters eliminate input noise, remove glitches and spikes and provide debouncing for digital switches and relays. Digital I/O watchdogs protect against a variety of fault conditions including computer and application crashes.

The NI 651x family also delivers innovative NI-DAQmx driver software technology on both Windows and LabVIEW Real-Time operating systems, offering superior ease of use and deterministic performance.

NI-DAQmx, the newest version of National Instruments measurement services software, includes automatic code generation for creating applications in NI LabVIEW, C, Microsoft Visual Basic .NET and C#. NI DAQ Assistant, a key feature of NI-DAQmx, guides engineers to fast, accurate input/output without requiring any programming. NI-DAQmx also offers multithreading streaming technology that delivers up to 100 times faster I/O throughput for concurrent operations and high-channel-count systems, as well as other advanced features including automatic timing, triggering and synchronization.

National Instruments Data Acquisition

By integrating commercial PC-based technologies and investing in innovative research and development, NI continues to lower the cost of measurement and control while improving system performance, accuracy and reliability. NI recently increased value for its data acquisition (DAQ) customers by reducing prices up to 25 percent worldwide for 13 of its most popular DAQ modules. Readers can learn more about the price reduction and view new prices on the Web at www.ni.com/dataacquisition.
