Low-cost, portable, Ethernet data acquisition system featuring 16 inputs for DI-8B signal conditioning modules (not included) and a maximum throughput rate up to 4800 samples/second. Includes Power cable, Ethernet cable, software, and documentation.

DATAQ Instruments’ DI-718Bx Series Data Acquisition/Data Logger System is designed for general purpose and standalone data logging applications that require signal conditioning. DI-718Bx instruments may be purchased with or without stand-alone capability. Instruments without this option must remain tethered to a PC’s Ethernet port (can be via a network) 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 amplifiers may be plugged directly into the DI718Bx and are the world’s smallest fully functional isolated analog signal conditioners. Each DI-8B module protects, filters, amplifies, and isolates an input signal and provides an advanced signal conditioning solution for nearly any industrial measurement. The compact nature of both the DI-718Bx and DI-8B modules combine to form the smallest data logger/acquisition instrument in its class.

All DI-718Bx instruments are supplied with four removable 16-position screw terminal connectors to provide access to the built-in DI-8B module backplane. Instruments are housed in a small (9"L × 7.29"W × 1.52"H; 22.9L × 18.5W × 3.86H cm) enclosure consisting of an aluminum base, all-steel wraparound



DI-718Bx High Speed Unlock Code

WinDaq Unlock Code


Unlocks WinDaq to allow recording speeds up to 4.8 kHz throughput. Unlock Code ONLY. No CD will be shipped. Please Note: If you are ordering this software for a device you already own, you MUST provide the serial number of your device under "Order Notes" during checkout to receive the unlock code. Please allow one (1) business day for processing.
