DI-718B 8B Module Data Logger System
Features
DATAQ Instruments’ DI-718B Series
is a four-product family of instruments
designed for general purpose and stand-
alone data logging applications that require
signal conditioning. Interface options are
USB or Ethernet. DI-718B instruments
may also be purchased with or without
stand-alone capability. Instruments
without this option must remain tethered
to a PC’s USB or Ethernet port during
data acquisition and use the PC’s own
program and memory to store acquired
data. Instruments with the stand-alone
data logging option feature a built-in
socket that accepts standard Secure Digital
(SD) memories to which acquired data
may be stored. SD memories are the
same commonly available mass storage
devices used with digital cameras and MP3
players.
Compact and low cost DI-8B ampliers
may be plugged directly into the DI-
718B and are the world’s smallest
fully functional isolated analog signal
conditioners. Each DI-8B module protects,
lters, amplies, and isolates an input
signal and provides an advanced signal
conditioning solution for nearly any
industrial measurement. The compact
nature of both the DI-718B and DI-8B
modules combine to form the smallest data
logger/acquisition instrument in its class.
All DI-718B instruments are supplied
with dual, removable, 16-position screw
terminal connectors to provide access
to the built-in DI-8B module backplane.
Instruments are housed in a small (13.81D
× 10.48W × 3.81 centimeters; 5⁷⁄16D ×
4¹⁄8W × 1¹⁄2H inches) enclosure consisting
of an aluminum base, all-steel wraparound,
and aluminum end plates.
Make Industrial Measurements
Through DI-8B Plug-in Signal
Conditioning Modules
Each channel on the DI-718B
accommodates one DI-8B module
providing a single channel of isolated input
protection, amplication, and ltering.
DI-8B modules are plugged into a socketed
backplane and are secured with a mounting
screw. Each channel has 4 corresponding
screw terminals for signal connections:
channel+, channel-, excitation+, and
excitation-. These terminals satisfy all
transducer inputs and provide sensor
excitation if necessary. Access to the DI-
8B modules is through a removable front
panel.
Stand-alone Data Logger
Operation
Use an SD Card to record and store
data—up to 2GB. A FIFO memory
conguration allows the DI-718B to record
continuously using a circular buffer or
record-until-full approach. A push button
allows manual start/stop control over the
recording process. A multi color LED
shows instrument status (Record, Standby,
Busy, Error).
Wide Range of Throughput
Rates
Supports sample throughput rates from
0.0034 Hz up to 4800 Hz when acquiring
data with a PC or from 0.0017 Hz (6.1
samples per hour) to up to 14,400 Hz
when recording to removable SD memory
(stand-alone data loggers).
High Resolution
14-bit resolution analog to digital
conversion provides a responsive
instrument capable of registering changes
as small as one part in 8,192 (±0.012% of
the full scale measurement range).
Remote Control Jack
Built-in remote control jack accepts
a standard 3.5mm stereo phone plug
(included). Provides easy access to remote
events (WinDaq Acquisition feature) and
stop/start remote recording.
File Protection
When powered down unexpectedly, the
DI-718B Stand-alone model retains all
acquired data on its memory card.
Includes Software
Be up and running minutes out of the box
with W
INDAQ software. WINDAQ/Lite
Recording and Playback software is
included free with the purchase of every
DI-718B instrument. Record at rates up to
1000 Hz using W
INDAQ/Lite Acquisition
software. W
INDAQ/High Speed option
allows you to record data as fast as the
instrument will allow. Use W
INDAQ
Playback software (WWB) to review,
measure, compare, and analyze waveform
data during or after a recording session.
Conguration Software is included for
all stand-alone data loggers allowing a
complete data acquisition conguration
to be designed and downloaded to the DI-
718B from any local or remote PC. Upload
software is also provided to allow you to
read data stored to SD memory over the
DI-718B’s Ethernet interface.
