Dataq DI-720 Series Data Acquisition Systems

General Purpose Data Acquisition System with 32 Single-ended Analog Input Channels
Produktnummer: DI-720

The DI-720 Series and DI-730 Series are families of instruments that offer 14-bit resolution and 150-200kHz waveform recording capability. They communicate through your PC's parallel port or an optional Ethernet or USB interface.

Use the DI-720 for general purpose applications where pre amplified signals are acquired. Examples are process monitoring, and many medical research applications.

Use the DI-730 for wide dynamic range measurements, especially those involving AC or DC electric motors. Examples include paper, aluminum, and steel mills; high speed trains; and rail and seagoing locomotion. The high sample rate, exceptional isolation, and CMR characteristics of the DI-730 make it very well suited for maintenance and troubleshooting of DC drive systems. Other applications include RPM measurements from motor/generators, supply voltage and current measurements, and field current measurements from drive-roll, braking, and take-up motors. See pages 11 and 12 for Application Close ups.

The Ethernet communication option connects DI-720 and DI-730 Series products to any local area network (LAN). Direct Internet access is also possible. This patented (US 7,792,139 B2) communication option uses standard CAT- 5 cable to yield continuous data acquisition throughput rates up to 180kHz. Multiple DI-720/730 products (each equipped with an Ethernet interface) may be daisy-chained together to form an ad-hoc extended network of autonomous, yet fully synchronous data acquisition stations. Each station can sample at a different rate (up to 180kHz throughput) and still maintain full synchronization. Station separation can be as far as 100 meters.
