National Instruments USB-6229

The National Instruments USB-6229 is a multifunction data acquisition (DAQ) device designed for versatile measurement and control applications. With up to 32 single-ended or 16 differential analog input channels, it provides a 16-bit resolution through its analog-to-digital converter (ADC), achieving a maximum sample rate of 250 kS/s per channel. Users can choose between I/O connector options featuring either 128 screw terminals or a combination of 30 BNC and 60 screw terminals. The USB-6229 supports various input ranges of ±10 V, ±5 V, ±1 V, and ±0.2 V, with a maximum input voltage of ±11 Volts and an input current limit of ±20 mA during overvoltage conditions. This device features robust overvoltage protection on all analog input and sense channels, ensuring reliability in demanding environments.

In addition to the analog inputs, the USB-6229 includes four analog output channels, also providing 16-bit resolution and varying update rates depending on the number of active channels. For a single output channel, the update rate reaches 833 kS/s, while for four channels, it operates at 625 kS/s per channel. The device is equipped with a frequency generator channel operating at base clocks of 10 MHz and 100 kHz, maintaining a high accuracy of 50 ppm.

Physically, the USB-6229 measures 10.5 x 6.73 x 1.75 inches and weighs 2 lb 11 oz. It operates effectively within a temperature range of 0 ºC to 45 ºC and has a storage temperature range of -20 ºC to 70 ºC. The device endures operational and non-operational vibrations of 0.3 grms and 2.4 grms, respectively, across a frequency range of 5 Hz to 500 Hz. The USB interface ensures compatibility with USB 2.0 high-speed or full-speed specifications, making setup and integration straightforward for a variety of applications. The USB-6229 is backed by a three-year warranty, and detailed user and maintenance manuals are available for download. For pricing information, please consult a sales representative.
