DI-718B Data Acquisition and Data Logger Products

Supports DI-8B Amplifiers

Product Features

  • This model is soon to be discontinued. Please consider the DI-4718B as a direct replacement. See comparison
  • Measures temperature, pressure, flow, current, voltage, and more using isolated 8B amplifiers.
  • Low-Cost, Portable, USB or Ethernet Data Logger. This product is similar to the DI-710 Series but with Signal Conditioned inputs.
  • Eight DI-8B signal-conditioned analog inputs. For a 16 channel version see the DI-718Bx Series.
  • Stand-alone data logger option allows in-the-field measurements to be saved to Secure Digital Cards (SD).
  • 14-bit analog to digital conversion.
  • Includes WinDaq Software.
  • Record from as low as 0.0017 Hz to as much as 14,400 Hz (using SD card 101014-2G) with Stand-alone models or from 0.0034 Hz up to 4,800 Hz with PC-connected instruments (WinDaq Unlock Code 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. Mix and match modules as needed.

Products in the Series


The DI-718B is an eight-channel, DI-8B module data logger system. Each DI-718B accepts up to eight 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 erasable sticker on the top of the instrument allows easy identification of all installed DI-8B modules.

DI-718B Series options include interface type and PC-connected or stand-alone data logger operation. Interface options are USB or Ethernet. 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 16MB to 2GB are supported. 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.

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, amplification, and filtering. DI-8B modules are plugged into a socketed backplane and are secured with a mounting screw. Each DI-718B 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 front panel.

Powerful Data Acquisition Server Capability

DI-718B Stand-alone data loggers are the first in their price range to 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 DI-718Bs provide the most power and flexibility. A DI-718B with an Ethernet interface and built-in memory transparently becomes 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 a standard SD card (not SDHD or SDxC) with a speed of 13x or greater. If sampling at speeds higher than 2kHz we recommend using DATAQ part number 101014-2G to record your data. This card has been tested and approved by DATAQ Instruments engineers.

Fast Throughput Rate

Supports sample throughput rates to 14,400 samples per second (using SD card 101014-2G) to SD with stand-alone Models and 4800 samples per second to PC with PC-connected Models. WinDaq Unlock Code 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 USB port or an Ethernet port using the supplied cable. 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-718B instrument. WinDaq/Lite operates at a maximum throughput recording rate of 1,108 Hz with a DI-718B 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-718B. 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.

Looking for the same features without signal conditioned inputs?

Our DI-710 Series Data Logger provides all the same great features as the DI-718B Series - without the built-in DI-8B backplane. View our complete line of Data Loggers.
