Ethernet Data Acquisition and Data Logger DI-710-ELS
DATAQ DI-710 General-purpose Ethernet Data Acquisition System with Windaq software. Features 8 differential or 16 single-ended analog input channels, 4,000 Samples per second throughput, 14-bit measurement resolution, and full scale ranges of ±10mV, ±100mV, ±1V, ±10 V full scale.
The DI-710 Series of products is a family of instruments for general purpose and stand-alone data logger data acquisition applications. Options include interface type, input voltage range, and PC-connected or standalone data logger operation. Interface options are USB or Ethernet. Gain ranges have selectable factors per channel of 1, 2, 4, and 8, or 1, 10, 100, and 1000. 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 16 MB to 2 GB 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.
- Includes a DI-710-ELS instrument, a 5-foot crossover Ethernet cable, a power supply, a screwdriver for signal connections
- 16 single-ended, 8 differential analog inputs.
- Measurement range of ±10mV to ±10V
- Allows in-the-field measurements to be saved to Secure Digital (SD) cards, or stored to a PC in real time using WinDaq software
- Built-in Real Time Clock allows automatic time and date stamping of data acquired to SD memory when used in the stand-alone mode.
- 14-bit analog to digital conversion.
- Includes WinDaq Software.
- Record up to 14,400 Hz in stand-alone mode using high speed SD card (model 101014-2G)
