Description
DI-722 General-purpose USB Data Acquisition System with Windaq software. Features 16 differential or 32 single-ended analog input channels, 50,000 Samples per second throughput, 14-bit measurement resolution, and full scale ranges of ±2.5, ±5, ±10, ±20 V full scale.
The DI-722-EN offers 14-bit resolution and 180,000 Samples per second waveform recording capability. Use the DI-720 for general purpose applications where pre amplified signals are acquired. Examples are process monitoring, and many medical research applications. Channel expansion up to 240 channels is possible with expanders.
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 150kHz. 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 50kHz throughput) and still maintain full synchronization. Station separation can be as far as 100 meters.
