2008年4月8日消息，NI宣布推出NI USB-6509，一款供以动力的总线便携式USB数字化I/O设备，用于大范围的数据收集。由于具备96双向数字化I/O通道和即插即用USB接口，该设备是工业控制和自动化测试应用的理想选择，此设备所拥有的多项功能已足够用于多目标数据采集和学术应用。
工业特征设置包括可编程级，数字化I/O看门狗计时器，改变探测和可编程输入过滤器。由于具备可编程动力级，工程师们可以预确定USB-6509设备供以动力的等级，确保一致性。当与一些工业执行器连接时，如泵、阀、电机或继电器，该设备的可靠操作性显而易见。数字化I/O看门狗可探测到多种故障情况，如电脑死机、对用户自定义的安全级别实现自动反映。通过改变探测，在数字线改变之后，设备能自动引发应用以执行阅读操作。同样的，工程师们可以消除无意识的小过失并避免由可编程输入过滤器噪音引起的错误示数。
96通道设备可与晶体管-晶体管逻辑电路，互补金属氧化半导体和5V数字逻辑级相兼容，8根线的每一个端口都是可单另配置输入输出的。USB-6509可驱动外部数字服务，如电流为24 mA的固体继电器（SSRs）。总线设备通过数字输出可达215mA。可选择的12VDC电源可用于额外的源电流。
USB-6509与NI- DAQmx驱动软件一起工作，其简单易用，有可用于编程的直接界面。设备还可以与NI LabVIEW, NI LabWindows™/CVI, ANSI C/C++, Visual Basic .NET, C# 和Visual Basic 6.0相兼容。更多信息，读者可登录

National Instruments Introduces High-Density Industrial Digital I/O for USB
April 8, 2008 – National Instruments today announced the NI USB-6509, a bus-powered, portable, USB digital I/O device for acquiring data in a broad range of applications. With 96 bi-directional digital I/O channels and plug-and-play USB connectivity, the device is ideal for industrial control and automated test applications yet versatile enough for general-purpose data acquisition and academic applications. The
The industrial feature set includes programmable power-up states, digital I/O watchdog timers, change detection and programmable input filters. With programmable power-up states, engineers can pre-define the state in which the USB-6509 device powers up, ensuring consistent, reliable operation when connected to industrial actuators such as pumps, valves, motors or relays. Digital I/O watchdog timers can detect a variety of fault conditions, such as a computer crash, and automatically respond by setting the outputs to a user-defined safe state. With change detection, the device automatically triggers an application to perform a read operation after a digital line changes state. Also, engineers can eliminate unintended glitches and spikes in input data and avoid false readings caused by noise with programmable input filters.
