2686A Data Logging System
8
2680 Series
Top precision and
scalability for standalone
or networked data
acquisition
The Fluke 2680 Series data acqui-
sition systems combine the best
of lab precision with the rugged
flexibility required in rapidly
changing industrial applications.
Whether you choose the 2680A Data
Acquisition System with high-speed
10/100BaseT Ethernet network
support or the 2686A Data Logging
System, you can seamlessly expand
your system any time, 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 2680 Series
20-channel analog input modules.
The sixth slot is reserved for a 2680
Series 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 channel count to
120 in a single chassis.
You can also link multiple 120
channel 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.
Key features
• 120 channel capacity chassis
designed for small- and large-
scale precision data acquisition
applications.
• User-scalability from 20 to
120 universal analog input
channels, which can include
digital input/output and alarm
contact outputs in a single
chassis.
• Universal input modules
provide precision measurement
of thermocouples, dc voltage, ac
voltage, ohms, RTDs, thermis-
tors, current, frequency. Connect
any input type to any channel to
match your application require-
ments—no “wasted” channels.
• Superior thermocouple
measurement accuracy
(J, K, R, S, T, N, L, U, C, B)
• Multiple speed and scan
selections
• Universal input conditioning
for any input, on any channel,
any time (V dc, V ac, ohms,
frequency, RTD, thermocouple,
thermistor or current).
• Optional precision, high-isola-
tion analog universal input
module (PAI) or fast scanning
analog universal input module
(FAI) to connect and measure
virtually any electrical or phys-
ical parameter.
• Computed channels, in addition
to the 20 analog channels, each
mainframe has 60 math channels
that perform custom calculations
using addition, subtraction, multi-
plication, division, log, natural
log, exponent, square root,
absolute value, and integer func-
tions. Math channels feature the
same alarm capability as analog
channels, which saves having to
perform separate post calcula-
tions on channel data. It is also
especially useful for monitoring
and alarming on real-time calcu-
lated values such as power, flow,
volumes, pressure, and more.
• Fluke DAQ software which
controls all functions and data
files, communicates with and
controls Fluke 2680A Series,
NetDAQ
®
and Hydra Series III
products and provides real-time
and historical trending.
• 20 digital I/O and 8 form C,
1 A relay output module
for hard control of equipment.
• Multiple power sources:
100 V to 240 V and 9 V dc to
45 V dc.
