Description
DATAQ Instruments announces model DI-785, a new 32-channel data acquisition system designed specifically to accept DI-5B style modular signal conditioners and based on our Third Generation Ethernet (3GE) communications. The DI-785 is packaged in an enclosure that measures 16.5W × 18.5D × 3.5H inches (42.9W × 47D × 8.9H centimeters) that is suitable for placement on a desktop, or can be mounted in a standard 19-inch rack using optional brackets. It’s also the first product from DATAQ Instruments to feature a built-in switching AC power supply, allowing it to be powered directly from AC line voltage. The DI-785 features 14-bit resolution, programmable gain per channel of 1, 2, 4, and 8, a maximum sample throughput rate up to 180,000 samples per second, and two built-in 16-channel DI-5B module backplanes allowing up to 32 signal-conditioning modules. Measurements include thermocouple, voltage, strain, frequency, process current, RTD, and potentiometric.
The Ethernet communications interface connects the DI-785 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-785 and/or DI-788 products may be daisy-chained together to form an ad-hoc extended network of autonomous, yet fully synchronous data acquisition stations. Add any DI-720 and/or DI-730 for a complete data acquisition system for almost any measurement. Each station can sample at a different rate (up to 150kHz throughput) and still maintain full synchronization. Station separation can be as far as 100 meters.
