Fluke 2680 Series:
A powerful choice

The Fluke 2680 Series offers the
choice of networked data acquisi­tion, stand-alone data logging, or a
combination of both. Choose from
two basic chassis models:

2680A Data Acquisition
System chassis

The Fluke 2680A Data Acquisition
System is the choice for multi­channel applications requiring reli­able Ethernet communications. It
features a front-end style data
acquisition system that communi­cates and distributes data any­where you need it to go. The
10BaseT and 100BaseT communi­cations interface makes it compati­ble with both older and newer
network installations.

2686A Data Logging
System chassis

The Fluke 2686A Data Logging
System writes data to a memory
card for easy retrieval and storage,
making it ideal for remote locations
and mobile or non-computer
assisted data logging applications.

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 meas­urements. The 2680A-FAI module
provides chassis throughput rates
of more than 3,000 channels-per­second. Specially manufactured
field effect transistors (FETs) allow
up to ± 50 V input, and channel­to-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 config­ured for stand-alone data logging
operations by simply selecting a
preset configuration from the mem­ory card. It can also be used in net­works 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 com­bination 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 120­channel systems together seam­lessly for the widest possible view
of your data. And, with TCP/IP
connectivity, you can connect to
existing LANs to distribute informa­tion 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 thou­sands 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 high­precision, 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 meas­urement 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 resolu­tion 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 displace­ment sensors can be easily incor­porated into your measurement
system.

2680A-DIO: Digital I/O and
relay outputs add control

For data acquisition systems that
also require control functionality,
the Fluke 2680A-DIO digital I/O
and relay output module provides
20 digital I/O and eight hard-con­tact 1 Amp form-C relays. This
equips each chassis to respond to
a wide range of alarm or control
situations. The 2680A-DIO also
includes an up/down counter with
preset start count capability, so
you don’t need to begin all counts
at zero.

2680A-180: Universal Input
Module requires no external
signal conditioning

Fluke’s patented Universal Input
Module is included with all Fluke
data acquisition products, provid­ing unparalleled thermocouple
accuracy and compatibility with a
broad range of diverse inputs. The
Universal Input Module enables
you to easily measure just about
any electrical or physical parame­ter without changing hardware or
adding external signal condition­ing. You can connect any combina­tion of dc voltage, ac voltage,
thermocouples, current, RTD,
resistance (2- or 4-wire), or fre­quency measurement inputs
directly to the input module.

Fluke DAQ Software makes
it easy to get the most out of
your data

Each Fluke 2680A and 2686A
comes with our powerful, highly­flexible, yet easy-to-use Fluke DAQ
Configuration Software. Fluke DAQ
allows you to configure the 2680
Series for:

•

Input type

•

Alarms

•

Math functions

•

Totalizer function

•

Digital I/O lines

•

Scan speed

•

•

Trigger type

You can use Fluke DAQ Software to
set up data files, collect and chart
data in real-time or historical
mode, and manage memory card
files. Using Fluke DAQ, you can
collect data from your system the
way you need to and distribute it
where you want it. And you can
share data with others, anywhere
on your LAN or anywhere around
the world using Web servers.

Fluke DAQ Software also
enables you to integrate Fluke
NetDAQ

®

data acquisition products
(2640A and 2645A) into your
2680 Series system, providing
almost unlimited channels working
together seamlessly.

Optional software extends
system capabilities

Fluke has partnered with industrial
software developer Indusoft to cre­ate additional tools to extend the
power of your 2680 Series system.
Optional software tools allow you
to create human machine inter­faces and develop custom applica­tions that interact with other
equipment and software packages.

Fluke 2680A-DEVSW:
Development software for
HMI design

The optional 2680A-DEVSW tool is
based on Indusoft Web Studio, an
object oriented development soft­ware program that works with
Fluke DAQ Software. This unique
development system allows pro­grammers and non-programmers
to develop modern human
machine interfaces (HMI) which
open graphical windows to your
application.
