2680A-FAI: The speed to
capture dynamic process
changes
The Fluke 2680A-FAI (Fast Analog
Input) is a perfect choice when you
need a lot of information in a hurry
and still need to maintain a high
degree of accuracy for your meas-
urements. The 2680A-FAI module
provides chassis throughput rates
of more than 3,000 channels-per-
second. Specially manufactured
field effect transistors (FETs) allow
up to ± 50 V input, and channel-
to-channel isolation well above
the 15 V industry norm, to give
you more confidence in the
integrity of your measurements.
The system comes with a 16 MB
ATA memory card, and supports ATA
flash memory cards of up to 1 GB to
provide the memory capacity you
need. The 2686A is easily config-
ured for stand-alone data logging
operations by simply selecting a
preset configuration from the mem-
ory card. It can also be used in net-
works in tandem with the 2680A
to provide the extra data security of
a memory card.
Scale your system to meet
your needs
With the Fluke 2680A and the
2686A, you can seamlessly expand
your system from 20 to more than
2,000 channels just by adding
modules and chassis. Both models
feature six slots in each chassis
that you can fill with modules as
needed to meet your application
requirements. Five slots in each
chassis are available for any com-
bination of 20-channel analog
input modules available for the
2680 Series. The sixth slot is also
available for a digital I/O relay
module to add control capabilities
to your system. If you don’t need
the sixth slot for control, you can
plug in an additional analog input
module, increasing your input
channel count to 120 in one chassis.
You can also link multiple 120-
channel systems together seam-
lessly for the widest possible view
of your data. And, with TCP/IP
connectivity, you can connect to
existing LANs to distribute informa-
tion wherever it needs to go.
Whether you need speed and
throughput, isolated precision, or
digital I/O and relays, the Fluke
2680 Series can scale up to thou-
sands of channels to meet your
needs. Buy just the modules you
need in the combinations you need
and expand your system as your
requirements grow.
2680A-PAI provides high
precision and high isolation
for the most demanding jobs
The Fluke 2680A-PAI (Precision
Analog Input) 20-channel high-
precision, high-isolation module
serves the most demanding jobs
where precision is paramount and
isolation is critical. Some of the
most notable applications for this
module include temperature meas-
urement in semiconductor and
pharmaceutical manufacturing, as
well as nuclear plant performance
monitoring. The 2680A-PAI
module offers 300 V of isolation
on two channels and 150 V on 18
channels, as well as 18-bit resolu-
tion and excellent thermocouple
accuracy, all in a scalable system.
Both the 2680A-FAI and the
2680-PAI modules support a wide
range of inputs including dc volts,
ac volts, RTD, Ohms, thermocouple,
thermistor, dc current, ac current,
and frequency. Other sensors and
transducers, such as load cells,
pressure sensors, and displace-
ment sensors can be easily incor-
porated into your measurement
system.
