Low Cost DAQ Modules Sport Pricey Features

Reporting performance levels associated with more costly products, the DI-158 series data-acquisition (DAQ) modules deliver sampling rates of either 14 or 28.8 ksamples/s and provide four fixed differential analog input channels with 12 bits of resolution. They also include a channel gain scan list, two d/a outputs with a ±10V range, four bits of general-purpose digital I/O, and USB or Ethernet interfaces. The DI-158 series includes three modules varying in interface type and input voltage range. The DI-158-U provides selectable gain ranges per channel of 1,2,4, and 8 with a full-scale range of ±10V. The DI-158-UP and DI-158-EP provide ±64V full scale at a gain factor of 1 and per-channel, selectable gains of 1, 2, 4, 8, 16, 32, 64, 128, 256, and 512. Prices start at $99 each.
