Akron, OH. DATAQ Instruments has announced the complementary models DI-4108 and DI-4208 USB data-acquisition systems. Both instruments are identical except for measurement range and can be connected for higher channel counts and mixed measurement ranges using DATAQ Instruments’ ChannelStretch technology.
Common features include eight differential analog inputs (armored to withstand up to 120 VRMS and seven bidirectional discrete ports. Two ports can be programmable as a counter or frequency input. The analog inputs are multiplexed to an ADC that provides 12- to 16-bit resolution as a function of sample rate. Sample rate ranges from 2.2 samples per hour to 160,000 samples per second. Model DI-4108 provides six measurement ranges from ±200 mV to ±10 V. Model DI-4208 supports ±2 to ±100 V. All ranges are programmable per channel, and instruments may be combined with ChannelStretch in any combination up to 128 analog channels and 112 digital ports.
Included is DATAQ’s WinDaq software to allow ready-to-run data acquisition, display, playback, and analysis as well as .Net classes and ActiveX controls for programming the DI-4108 or DI-4208 under Windows. A documented instrument protocol is also provided for other operating systems.
