Ethernet Data Acquisition and Data Logger DI-718B-ES
DATAQ DI-718B-ES Low-cost, portable, Ethernet data acquisition system with stand-alone capability (records to SD card) featuring 8 inputs for DI-8B signal conditioning modules (not included), a maximum throughput rate up to 14400 samples/second to flash memory. Includes power cable, Ethernet cable, bare stereo jack for remote control operations, software, and documentation.
DATAQ Instruments’ DI-718B Series is a four-product family of instruments designed for general purpose and standalone 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 amplifiers may be plugged directly into the DI718B 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.
- Includes a DI-718B-ES instrument, a 5-foot crossover Ethernet cable, a power supply and adapter, a 3.5mm stereo jack for remote control, a screwdriver for signal connections
- Measures temperature, pressure, flow, current, voltage, and more using isolated 8B amplifiers
- Stand-alone data logging option allows in-the-field measurements to be saved to Secure Digital Cards (SD)
- Eight DI-8B signal-conditioned analog inputs
- 14-bit analog to digital conversion
- Record up to 14,400 Hz in stand-alone mode using high speed SD card
- Up to 4800 Hz Sample Throughput Rate when connected to PC
