National Instruments PCI-6517 Digital I/O Device

The NI PCI-6517 (Part Number: 779083-01) Digital I/O Device has 32 sink output lines, bank isolation, and ±30 VDC maximum switching voltage. This device is suitable for general-purpose data acquisition applications, automated manufacturing test, and industrial control. The PCI 6517 can be linked to a variety of actuators, sensors, and 24 V electronic instruments. This Digital I/O Device can be used with NI-DAQmx software, which comes with the technology to make application development go more quickly. Several of the useful features in NI-DAQmx are high-performance multithreaded streaming technology, automatic code generation, and the DAQ Assistant. The device can be programmed using software packages or application development environments (ADEs) such as LabVIEW or LabWindows/CVI.

When this device is at a temperature of 25 °C and the user is utilizing all 8 lines in a port, 75 mA maximum can be output from each line. Subsequently, the port can have an aggregate most extreme current output of 600 mA (75 mA x 8 = 600 mA). If each of the 8 lines are not being utilized, the port can yield 600 mA, yet no line can output more than 350 mA. The device is equipped with a 37-pin male DSUB I/O connector.

The NI PCI 6517 Digital I/O Device is equipped with digital I/O watchdogs, which have the capability to notice application and computer errors. The National Instruments digital I/O watchdogs help safeguard against the following: PCI bus failure, computer crashes, driver crashes, and application crashes. The digital outputs go into a safe recovery setting when a fault is noticed by the watchdogs. The digital I/O watchdogs additionally guarantee safe recovery. Another beneficial feature of the PCI-6517 is the change detection feature. This feature triggers the user’s application and brings back I/O information after a digital incident with low processor usage. This device also has programmable input filters, which eradicate glitches/spikes and get rid of noise.  

The PCI-6517 weighs 2.5 oz, and measures 5.54 x 4.47 in. in physical dimensions. It has recommended operating and storage temperature ranges of 0 °C to 55 °C and –20 °C to 70 °C, non-condensing operating and storage humidity ranges of 10% to 90% RH and 5% to 95% RH.
