Industrial USB/Ethernet Data Acquisition and Data Logger DI-4730

Brand: DATAQ
Product code: DI-4730

    The DI-4730 is the next-generation of our very popular DI-730 series. The two are functionally identical except that the DI-4730 supports both ChannelStretch™ channel expansion and stand-alone data logging to a removable USB flash drive (unlock code required). Suitable for a wide range of analog and discrete measurements, the DI-4730, in tandem with the included WinDaq software, allows real time data acquisition, playback, and analysis performance that covers an incredibly broad array of applications in both laboratory and industrial settings. With all eleven scan list items enabled (8 analog channels, one each counter and rate, and all discrete input ports in the remaining position) a total sample throughput rate of 220 kHz is supported.

    • Measurement range of ±10mV to ±1000VDC (or peak AC) over six ranges – ±1000V, ±100V, ±10V, ±1V, ±100mV, ±10mV full scale
    • Stand-alone capability to USB thumb drive (WinDaq/Pro Unlock Code required to record all channels to USB thumb drive – See Accessories)*
    • Up to 160,000 Hz Sample Throughput Rate using WinDaq Acquisition software
    • Up to 160,000 Hz Sample Throughput Rate in stand-alone mode using high speed microSD card
    • 12 to 16-bit analog-to-digital resolution
    • Power over Ethernet (PoE) included – run the device via USB, Ethernet, or PoE
    • Adaptable low-pass filter per channel
      • Corner frequency set as a function of sampling rate
    • Seven digital inputs
      • Support for rate measurements to 50 kHz
      • Support for 16-bit counter
    • Supports ChannelStretch™ multi-unit synchronization
