描述
这镍SCXI-1163(零件号:776572-63)是一个孤立的数字输出模块。该模块上有32个可用通道，它们被组织成8个独立的存储体，每个存储体有4条输出线。这SCXI-1163能够连接现场数字逻辑信号，消除接地环路问题，并将主机与有害电压隔离。这数字输入输出模块可以通过SCXIbus控制。因此，它可以很容易地集成到现有的SCXI系统中，并且不需要更多的DAQ仪器或电缆。如果直接连接到插入式DIO仪器，该模块还可以在并行模式下运行。它与大多数TTL和CMOS逻辑兼容。
当NI SCXI 1163数字输入输出模块处于多路复用模式时，数字输出线路或继电器由DAQ仪器上的数字线路控制。设置为逻辑高电平的位会在相关输出线上产生逻辑高电平。如果国家仪器公司SCXI-1163模块处于多路复用模式，控制DAQ仪器通过SCXIbus总线向模块发送更新。NI-DAQ 7驱动软件允许用户以每秒600次更新的速度更新所有线路——一次更新链接到所有32条线路。该驱动程序与软件包/应用开发环境(ade)兼容，如LabVIEW、LabWindows/CVI或Measurement Studio。此外，背面信号连接器有一个并行接口，用于并行模式。在并行模式下，更新速率基于模块的传播延迟和负责的DIO仪器的最高更新速率。此外，如果DIO仪器具有该功能，也可以获得频闪更新。
该器件的功耗要求典型值为60mA/组，最大值为80mA/组。它在存储体之间具有250 Vrms的共模隔离。这SCXI 1163配有一个50针凸形带状电缆后连接器和一个48针DIN C凸形前连接器。该设备的尺寸为1.2 x 6.8 x 8.0英寸。在物理维度上。
SCXI-1163R
The NI SCXI-1163 (Part Number: 776572-63) is an isolated Digital Output Module. There are 32 channels available on this module, which are organized into eight isolated banks with four output lines each. The SCXI-1163 has the capability to interface to field digital logic signals, removing ground-loop issues and segregating the host computer from harmful voltages. This Digital I/O Module can be controlled via the SCXIbus. Thus, it can be integrated with ease into existing SCXI systems and does not require more DAQ instruments or cabling. This module can additionally function in parallel mode if it is cabled straight to a plug-in DIO instrument. It is compatible with most TTL and CMOS logic.
When the NI SCXI 1163 Digital I/O Module is in multiplexed mode, the digital output lines or relays are controlled by digital lines on the DAQ instrument. A bit set to logic high creates a logic high at the related output line. If the National Instruments SCXI-1163 module is in multiplexed mode, updates are sent to the module by the controlling DAQ instrument via the SCXIbus. The NI-DAQ 7 driver software allows the user to update all lines at 600 updates per second–a single update links to all 32 lines. The driver is compatible with software packages/application development environments (ADEs) such as LabVIEW, LabWindows/CVI, or Measurement Studio. Additionally, there is a parallel interface to the back signal connector, which is meant for parallel mode. During parallel mode, update rates are based on propagation delays for the module and on the highest update rate of the DIO instrument in charge. Furthermore, if the DIO instrument has the feature, strobe updates are also obtainable.
The device has a power requirement of 60 mA/bank typical, and 80 mA/bank maximum. It has a common mode isolation of 250 Vrms between banks. The SCXI 1163 is equipped with a 50-pin male ribbon-cable rear connector and a 48-pin DIN C male front connector. The device measures 1.2 x 6.8 x 8.0 in. in physical dimensions.
