DaqBoard3031USB USB-Based, 16-Bit, 1 MHz Data Acquisition Board for OEM and Embedded Applications

Description

IOtech's USB 2.0 DaqBoard/3000USB Series offers high-speed, multifunction data acquisition in a low-cost, board-only design. Unique to the DaqBoard/3000USB Series is a low-latency, highly deterministic setpoint control output mode that operates independent of the PC. In this mode digital, analog, and timer outputs can respond to analog, digital, and counter inputs as fast as 2 µs; at least 1,000 times faster than other products that rely on the PC for decision making.

The DaqBoard/3000USB Series has a 16-bit, 1 MHz A/D converter coupled with 16 single-ended, 8 differential analog inputs (/3001USB and /3005USB models), 64 single-ended, or 32 differential analog inputs (/3031USB and /3035USB models). Four of the analog inputs can be configured as four differential thermocouple inputs (all models). Each channel can be software-­configured for a different voltage range, as well as for single-ended or differential bipolar input, or thermocouple input (up to four channels). While all analog input ranges on the DaqBoard are calibrated at the factory, the DaqBoard also allows user calibration through a separate program called DaqCal. This software stores its calibration results in tables that are separate from factory calibration.

Twenty four TTL-level digital I/O lines are included in the DaqBoard/3000USB Series. Digital I/O can be programmed in 8-bit groups as either inputs or outputs and can be scanned in several modes. Four 32-bit counters are built into the DaqBoard/3000USB Series. Each of the four counters accepts frequency inputs up to 20 MHz, and each counter channel can be configured in a variety of modes, including counter, period, pulse width, time between edges, or multi-axis quadrature encoder. The analog, digital, and counter inputs all can be read asynchronously under program control, or synchronously as part of an analog and digital scan group.

Four 16-bit, 1 MHz analog output channels are built into the DaqBoard/3001USB and /3031USB units. Each D/A output can continuously output a waveform that can be read from PC RAM or a file on the hard disk. Alternatively, a program can ­asynchronously output a value to any of the D/As for non-waveform applications. The DaqBoard/3000USB Series can use two of its 8-bit ports to generate a 16-bit digital pattern at up to 1 MHz, and its hardware also includes two 16-bit timer outputs.
