Dataq Data Acquisition System DI-718Bx
Sixteen channel, DI-8B-module data logger system
● Measures temperature, pressure, flow, current, voltage, and more
● Low-Cost, Portable, Ethernet Data Logger (external USB to Ethernet converter available)
● Sixteen DI-8B signal-conditioned analog inputs
● Stand-alone data logger option allows in-the-field measurements to be saved to Secure Digital Cards (SD)

● Record from as low as 0.0017 Hz to as much as 14,400 Hz (assumes SD latencies of 80 milliseconds or less) with Stand-alone models or from 0.0034 Hz up to 4,800 Hz with PC-connected instruments (WinDaq/HS required to achieve recording rates over 1,108 Hz with PC-connected instruments)
● Wide variety of measurement functions and ranges based on DI-8B module selections
The Dataq Data Acquisition Instrument DI-718Bx is a sixteen channel, DI-8B-module data logger system. Each Dataq Data Acquisition Instrument DI-718Bx accepts up to sixteen high-performance, plug-in (DI-8B) signal conditioning modules to include virtually any isolated, industrial-type signal. Because DI-8B modules are identical in pinout and size, they can be mixed or matched in any combination. Choose from thermocouple, true rms, voltage, strain, frequency, process current, RTD, potentiometric, or DC transducer—whatever suits your application. A eraseable sticker on the top of the instrument allows easy identification of all installed DI-8B modules.
The DI-718Bx Series offers the option of PC-connected or stand-alone data logger operation. Instruments with the stand-alone data logger option feature a built-in multimedia socket that accepts standard Secure Digital (SD) memories to which acquired data may be stored without a connected PC. SD memories are the same commonly available mass storage devices used with digital cameras and MP3 players. Memories ranging in size from 8MB to 2GB are supported. Instruments without this option must remain tethered to a PC’s Ethernet port or to a an accessible network during data acquisition and use the PC’s own program and memory to store acquired data.
Make Industrial Measurements Through DI-8B Plug-in Signal Conditioning Modules
Each channel on the Dataq Data Acquisition Instrument DI-718Bx accomodates one DI-8B module providing a single channel of isolated input protection, amplification, and filtering. DI-8B modules are plugged into a socketed backplane and are secured with a mounting screw. Each DI-718Bx channel has 4 corresponding screw terminals for your 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 top hatch.
Powerful Data Acquisition Server Capability
DI-718B Stand-alone data loggers offer data acquisition server capability. Acting as a server allows stand-alone instruments to locally and independently acquire data to their memory cards, and then make that acquired data available upon demand, either by plugging the memory card into a reader, or uploading via the Ethernet interface.
Ethernet-enabled Dataq Data Acquisition Instrument DI-718Bx's provide the most power and flexibility. The Ethernet interface and built-in memory allows the DI-718Bx to transparently become like any other computer on a network, able to share recorded data over a network to a PC on the other side of the facility, or over the Internet to a PC on the other side of the world. These stand-alone instruments can be added easily and seamlessly to existing networks without incremental bandwidth burdens, storing data in memory and uploading on demand. Stand-alone data loggers can also be controlled locally using multifunction push-button control and multi-colored, red, green, orange LED status indicator.
Recommended Memory Card
For optimal performance, DATAQ Instruments, Inc. recommends using a Lexar Professional 133X 2 Gigabyte Secure Digital Flash Memory Card to record your data. Memory cards are available through our online store.
Fast Throughput Rate
Supports sample throughput rates to 14400 samples per second (assumes SD latencies of 80 milliseconds or less) to SD with stand-alone Models and 4800 samples per second to PC with PC-connected Models. WinDaq/HS is required to achieve recording rates over 1,108 Hz with PC-connected instruments.
Easy to Connect & Use
Installs in seconds. Simply connect to your computer's Ethernet port or to any accessible network (cable not included). Connect power, then connect your signals to the provided screw terminal blocks. Stand-alone models just need a memory card and power.
Includes WinDaq Software
Be up and running minutes out of the box with WinDaq acquisition and playback software. WinDaq/Lite software is included free with the purchase of every DI-718Bx instrument. WinDaq/Lite operates at a maximum throughput recording rate of 1,108 Hz with a DI-718Bx Instrument. A special version of WinDaq acquisition software may be purchased (WinDaq High Speed Option) allowing you to record data at the speed of the instrument (up to 4800 Hz).
WinDaq Waveform Browser, our unrestricted playback and analysis software for Windows, is also included free with the purchase of every DI-718Bx. Use it to review, measure, compare, and analyze the waveform file after it has been recorded by WinDaq acquisition software. WinDaq> software products support up to 14 bits of measurement resolution.
