National Instruments PCI-6624 Counter/Timer Device

The PCI‑6624 (Part Number: 778834-01) Counter/Timer Device has eight counters, which each have three separate isolated inputs and a single isolated output. This Counter/Timer Device plays out a huge variety of counter/clock undertakings, including functions like occasion counting, era/frequency estimation, and pulse prepare generation. Example applications additionally incorporate the generation of re-triggerable pulses, two-signal edge division estimations, consistent cradled occasion counting, and persistent buffered pulse train estimations. The NI PCI‑6624 offers predominant modernly tough highlights for a wide exhibit of utilizations, such as automotive/aviation, mechanical/movement control, and assembling test. The device is equipped with a 100-pin female SCSI-II I/O connector.

The PCI-6624 Counter/Timer Device has 34 PFI lines, with eight outputs and 26 inputs. The PFI lines are unidirectional and can be set as outputs or inputs. An input cannot be configured as an output. Likewise, an output cannot be configured as an input via software. The inputs on the NI PCI-6624 can be driven referenced to the ground or supply of the external instrument linked to them. The inputs have a current limited that keeps the optical isolator safe. The optical isolator moves the externally linked signals to the TIO and a diode safeguards against reverse linked signals.

The most extreme practical exchange rate a TIO gadget can accomplish for cradled securing relies upon the accompanying variables: amount of accessible transport data transmission, processor speed, and working framework and application programming. To diminish the measure of bus action, restrain the quantity of gadgets producing bus cycles. Since coordinate memory to (DMA) exchanges are quicker than interfere driven exchanges, NI-DAQmx utilizes DMA as a matter of course for supported acquisitions. The NI PCI-6624 device has an oven-controlled crystal oscillator (OCXO) that gives a profoundly stable 10 MHz clock that can be used as a GATE or SOURCE for a counter. The device can be programmed using software packages or application development environments (ADEs) such as LabVIEW or LabWindows/CVI.

The PCI-6624 measures 6.9 x 4.2 in. in physical dimensions. The device has recommended operating and storage temperature ranges of 0 °C to 55 °C and -20 °C to 70 °C respectively.
