国家仪器 PXI-6511 数字 I/O 模块

国家仪器PXI-6511(部件编号:778967-01)是一款64通道,银行隔离,Sink/Source输入,±30 VDC基于PXI的数字I/O模块.它具有-30 V到30 V的数字输入电压范围,以及24 V的数字I/O逻辑电平.该型号被设计为工业级数字I/O接口,具有八组完全隔离的通道.如果软件应用或硬件(计算机)相关故障发生,PXI-6511可以使用集成的数字I/O看门狗触发切换到用户配置的安全输出状态,以确保安全检测和恢复故障状态.此外,可编程输入滤波器消除尖峰,并通过可软件选择的数字滤波器为数字继电器/开关提供足够的拒绝.

This module comes equipped with a high-density 100-pin keyed female SCSI connector that provides access to the digital inputs. The input lines on the National Instruments PXI-6511 consist of input photocouplers. These photocouplers react to both the voltage differential and voltage increase. With this module, the user can configure power-up states as required, ensuring device power-up in a predefined, known state. The user can have the power-up states defined simply by using the Measurement & Automation Explorer (MAX) tool. To eliminate glitches/spikes on the input lines, this model offers a digital filtering option. Filtering can also minimize the number of changes when it is used with the change detection feature.

The PXI-6511 is run using the NIDAQmx driver software which can be programmed with software packages or application development environments (ADEs) such as LabVIEW or LabWindows/CVI.

The NI PXI-6511 also allows the user to configure the digital I/O channels to pass across a digital filter stationed after the photocouplers. In addition, the user can define and control the timing interval the digital filter uses.

The NI device weighs 4.8 oz, and measures 8.38 x 5.12 in. in physical dimensions. It has recommended operating and storage temperature ranges of 0 to 55 °C and –20 to 70 °C respectively, operating and storage humidity ranges of 10 to 90% and 5 to 95%, operating and non-operating random vibrations of 0.3 grms and 2.4 grms respectively–all at a frequency range of 5 to 500 Hz.
