Table 1. NI 6624 Specifications Overview
Overview and Applications
National Instruments 6624 devices are industrial isolated timing
interfaces for PCI and PXI/Compact PCI bus systems. You can use the
eight 32-bit channel-channel optically isolated counter/timers of an
NI 6624 device to perform a wide variety of buffered measurements or
other counter/timer tasks, including position or quadrature encoder
measurement, edge counting, period measurement, pulse-width
measurement, frequency measurement, semiperiod measurement,
2-edge separation measurement, pulse-width-modulation (PWM)
generation, pulse, and pulse-train generation.
NI 6624 devices offer superior features and high value for
automotive test, industrial monitoring and manufacturing test
applications such as factory automation, embedded machine control,
and production line verification. NI 6624 devices have been designed
from top to bottom to incorporate the latest hardware technologies
and provide innovative features for applications requiring
ease of use, high reliability, and performance. NI 6624 devices
take advantage of the NI-DAQ software (version 7.2 or higher),
which includes NI-DAQmx technology to speed up application
development with many helpful features such as the NI DAQ Assistant,
automatic code generation, and high-performance multithreaded
streaming technology.
Hardware
Connect Sensors Directly with Channel-Channel Isolation
Isolation is a form of built-in signal conditioning that provides several
advantages. Isolation provides an extended voltage range for direct
connection to industrial sensors and actuators. Isolation also improves
signal quality and protects computer circuitry. NI 6624 devices provide
channel-channel isolation where every channel is physically and electrically
separated from the others, which breaks ground loops, improves commonmode voltage and noise rejection, and permits the two parts of the circuit
to be at different voltage levels. Many industrial applications require
isolation to protect the electronics from transient voltage spikes and
provide greater common-mode noise rejection in electrically noisy
environments containing machinery and inductive loads.
Counter/Timers Based on NI-TIO ASIC
NI 6624 devices are equipped with the NI-TIO ASIC, a National
Instruments counter and digital I/O ASIC for advanced timing and
counting applications. Each NI 6624 features two NI-TIO ASICs to
provide a total of eight counter/timers. Each counter has a gate, auxiliary,
and source input, which can be controlled by external or internal signals.
Each counter has one output that can be routed externally or to other
counters on the board. 20 MHz and 100 kHz timebases are available on
each device for use with each counter/timer. A hardware trigger can be
used to start multiple counters simultaneously.
Buffered Measurements
NI 6624 devices use the National Instruments MITE bus interface
controller to implement bus-master DMA transfers. As a result, you
can perform high-speed, continuous operations such as buffered
position encoder measurement and buffered period measurement.
You can perform up to three simultaneous DMA transfers on an
NI 6624. You can use interrupts for additional simultaneous
buffered transfers.

to make configuration and programming easy. NI 6624 devices take
full advantage of key NI-DAQmx software technologies such as
multithreaded streaming technology for dramatic improvements in
I/O performance and ease of use.
• Use NI DAQ Assistant to guide you to fast, accurate measurements
with no programming
• Use automatic code generation to create your application in
NI LabVIEW, ANST C, Visual Basic .NET, or C#
• Take advantage of multithreaded streaming technology for 1000X
performance improvements
• Use automatic timing, triggering, and synchronization technology
to make advanced applications easy
• Visit ni.com for more than 3,000 FREE software downloads to
jumpstart your project
• Use NI-DAQmx functions for jumper-free software configuration
of all counter/timer and digital I/O features without hardware
switches/jumpers
• Develop your application with easy and open programming in
LabVIEW, ANSI C, Microsoft Visual C++, C#, and Visual Basic .NET
NI 6624 devices each have a 100-pin connector, with a SOURCE,
GATE, AUX and OUT signal for each of the counter/timers and two
PFI inputs for start triggering.
RTSI
NI 6624 devices are equipped with the RTSI or PXI trigger bus for
multidevice synchronization. Timing signals on an NI 6624 device
can be routed to or from other devices in your system to perform
advanced timing and synchronization.
