Description

High-Speed USB and Ethernet Data Loggers, DI-4108-M and DI-4208-M from DATAQ Instruments.

DI-4108-M Programmable ranges: ±200, ±500 mV, ±1, ±2, ±5, ±10 V full scale
DI-4208-M Programmable ranges: ±2, ±5, ±10, ±20, ±50, ±100 V full scale

Product Features

  • 8 Analogue Input Channels
    Measure as many as eight system variables at once with programmable ranges per channel 

  • Differential Analogue Input Configuration
    Enhanced noise immunity and tolerance of common mode voltages.

  • 12- to 16-bit Measurement Resolution

  • Armored Inputs Absorb Mistakes
    Both Analogue and digital inputs are protected

  • Fast 160 kHz Sample Throughput Rate

  • Stand-alone Data Logger Operation
    Store data to flash drives at throughput rates up to 160kHz (requires AC power supply).

  • 15V Excitation
    DI-4108M provides 15V excitation to power sensors.

  • Pre/Post Tigger Storage to USB Memory
    Set trigger levels to record up to 2G (combined) of pre- and post-trigger data (total file size of 4G)

  • Auto Re-Trigger
    When using Triggered Storage, triggers can automatically reset, creating a new file with pre and post-trigger data each time the trigger level is breached.

  • Industrial Oriented
    DI-4108M comes with easy signal swapping connectors, stackable rugged enclosure and ground lug to provide better EMC immunity in harsh environment.

  • Supports ChannelStretch™ Channel Expansion*
    Connect as many as sixteen DI-4108s , DI-4208s, DI-4718Bs, and/ or DI-4730s to one PC. Synchronously acquire from as many as 128 and 112 Analogue and digital channels respectively.

  • Seven Digital Input Ports*
    Folds discrete I/O into the measurement process. Each bit is programmable as an input or as a switch and protected to 0-25 V dc.

  • Asynchronous Digital Switches
    Control external processes seamlessly while acquiring data.

  • Counter Channel
    Tallies the number of pulses applied. Useful for integrating rate information, like flow rate to volume, or simply the number of definable events.

  • Rate Measurement Channel
    Measures pulse rate where frequency carries information. For example: rpm or flow measurements.

  • Optional Power over Ethernet (PoE)
    The optional Power over Ethernet feature allows you to both communicate with and power the DI-4108 via the Ethernet connector, sparing the inconvenience and expense of running power to the unit.

  • Ready-to-run Software Support*
    Provided with ready-to-run WinDaq software for point-and-click DAQ performance with a real-time display, disk-streaming recording, and playback and analysis.

 

* WinDaq/Unlock required per device to use ChannelStretch™ and to record more than four total channels when using WinDaq software.
