National Instruments PCI-6513 Digital I/O Device

The PCI-6513 (Part Number: 778970-01, 778974-01) has a computerized channel alternative accessible for information lines to take out glitches on input information. When it is utilized with change recognition, separating can lessen the quantity of changes to look at and process. The user can design the advanced info channels to go through a computerized channel after the photocouplers; additionally, the user can control the planning interim for the channel employments. The channel square pulses that are shorter than half of the predefined timing interim pass beats that are longer than the predetermined interim. Halfway length pulses, pulses longer than half of the interim, however not as much as the interim, could conceivably pass the channel. The digital device is equipped with a 100-pin keyed female SCSI I/O connector. It has a maximum input voltage of ±30 VDC and a maximum input current of 12.5 mA per line. Part number 778974-01 is for the PCI-6513 Bundle. 

The channel works on the contributions from the photocouplers. Photocouplers turn on quicker than they turn off and pass rising edges speedier than falling edges. The user can empower floating on the same number of info lines as is essential for the application. All filtered lines share a similar planning interim, which ranges from 200 μs to 200 ms.  Inside, the channel utilizes two clocks: the sample clock and the channel clock. The sample clock on the NI PCI-6513 has a 100 ns period. The channel clock is produced by a counter and has a period equivalent to one portion of the predefined timing interim. The information signal on the NI PCI 6513 is inspected on each rising edge of the example clock, which is 100 ns. Nonetheless, an adjustment in the information signal is perceived if it keeps up its new state for no less than two successive rising edges of the channel clock.

The NI device is run using the NIDAQmx driver software which is compatible with software packages/application development environments (ADEs) such as LabVIEW, LabWindows/CVI, or Measurement Studio.

The PCI-6513 weighs 2.5 oz, and measures 5.54 x 4.47 in. in physical dimensions. It has a recommended operating temperature range of 0 °C to 55 °C.
