DS-MPE-DAQ0804 Analog & Digital I/O PCIe MiniCard

Description

The DS-MPE-DAQ0804 is a rugged, low-cost data acquisition PCIe MiniCard module with both analog and configurable digital I/O. It is ideal for adding analog I/O and digital I/O features to embedded and OEM applications requiring low cost, small size, and/or lightweight.

The DS-MPE-DAQ0804 offers 8 16-bit analog input channels, 4 16-bit analog output channels, and 21 configurable digital I/O lines in a PCIe MiniCard form factor with an extended operating temperature of -40°C to +85°C. The analog inputs offer single-ended and true differential capability, 4 programmable input ranges, and 100KHz aggregate sample rate. Outstanding features of the DS-MPE-DAQ0804 analog input circuitry include an integrated programmable timer to control A/D sample rates automatically, resulting in precise timing plus significantly reduced processor overhead compared to software polling techniques. The 2048-sample data FIFO with a programmable interrupt threshold further reduces processor overhead by reducing the interrupt rate required to transfer data from the board to the application. With these features, DS-MPE-DAQ0804 can offer accurate, full-speed performance in any single-board computer regardless of processor speed.

The 16-bit analog outputs offer 2 programmable output voltage ranges. An integrated precision, low-drift voltage reference ensures a lifetime of accurate performance across the full operating temperature range. A built-in waveform generator with 2K sample buffer enables the board to be used in stimulus applications such as sonar, laser light control, and other applications.

The 21 buffered digital I/O lines feature programmable directions in groups of 4, 6, and 8 bits. The digital I/O lines can also be configured as either 24-bit pulse width modulators or 32-bit counter/timers, driven by the on-board 50 MHz clock.

All I/O signals are provided on two miniature connectors, one for the analog signals and one for the digital signals. The connectors feature positive locking for maximum reliability in high-vibration environments.

Extended temperature capability (-40°C to +85°C) enables the board to operate in environments with extreme temperature swings, such as vehicles or outdoor installations. In addition, the board may be custom-configured with 0-ohm resistors in place of jumper blocks for increased ruggedness in high-vibration environments.

Diamond’s free Universal Driver software, included with the DS-MPE-DAQ0804, simplifies programming effort for all the board’s I/O functions under both Windows and Linux operating systems.

The DS-MPE-DAQ0804 product comes with the PCIe MiniCard hardware assembly, a cable kit with one analog cable and one digital cable, and a hardware kit containing mounting screws.
