Description
DI-730 High Voltage Ethernet Data Acquisition System with Windaq software. Features 8 wide range differential analog input channels, 150,000 Samples per second throughput, 14-bit measurement resolution, and full scale ranges of ±10, ±100 mV, ±1, ±10, ±100, ±1000 V full scale.
The DI-730-EN offers 14-bit resolution and 150,000 Samples per second waveform recording capability. 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 make it 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.
Connect to any local area network (LAN). Direct Internet access is also possible. This patented (US 7,792,139 B2) communication option uses standard CAT5 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.
