AKRON, OH – DATAQ Instruments’ new Ethernet data acquisition models
DI-785 and DI-788 represent a triple competitive threat in terms of synchronization, simplified deployment and channel density. Multiple units, separated by over 100 meters, can synchronize at samples rates as high as 180 KHz per unit by simply daisy-chaining ordinary CAT-5 cables between them. With up to 32 fully isolated channels per box, and support for as many as eight simultaneously connected boxes, no other products offer the isolated channel density and speed of these new models. Both are available for immediate delivery.
The DI-785 has two built-in 16-channel 5B module backplanes. Into these up to 32 5B-type signal conditioning modules can be installed, bringing the universe of isolated industrial measurements to the instrument, including thermocouple, voltage, strain, frequency, process current, RTD, potentiometric and RMS.
The DI-788 is supplied with two built-in 16-channel 8B module backplanes that permit up to 32 8B-type signal conditioning modules to be installed. 8B modules support virtually any isolated industrial measurement such as thermocouple, voltage, strain, frequency, process current, RTD and potentiometric. Soon to be released is a line of RMS measurement modules.
Both the DI-785 and -788 offer 14-bit resolution, programmable gains per channel of 1, 2, 4 and 8, and a maximum sample throughput rate to 180,000 samples per second.
Each unit includes DATAQ Instruments’ patent-pending synchronous data acquisition interface, which offers advantages not found in other Ethernet data acquisition systems. Competing Ethernet instruments must cable to external hubs or switches, but DATAQ Instruments’ units embed the Ethernet switch in the instrument. Consequently, an instrumentation network can be constructed using minimal cables by simply connecting one instrument to another in a daisy-chain fashion. Data are acquired across multiple units synchronously, with zero latency between them. Compared to LXI-based products, DATAQ Instruments’ synchronous data acquisitioninterface is designed for continuous, long-term, high-speed, and distributed multi-channel data acquisition. In contrast, the synchronizing components of LXI provide accurate time stamps, event marks, and process initiation, not high-speed sample-by-sample synchronization.
Primary applications for the DI-785 and -788 include distributed and synchronized maintenance and troubleshooting measurements in paper mills, steel and aluminum rolling mills, hydraulic metalworking presses injection-molding, and more.
