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 multi-channel 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. The system comes
with a 16 MB ATA
flash memory cards of up to 1 GB to provide the memory
capacity
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.

Technical Data
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
120 in one 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. Buy just the modules you need in the combinations you need and expand your system as your
requirements grow.
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-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.
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 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.
