The National Instruments USB-6353 Multifunction I/O Device (Part Number: 781441-01) is engineered to deliver versatile and high-performance data acquisition and control capabilities. This device features 32 single-ended analog input channels that can also function as 16 differential channels, with a maximum sample rate of 1.25 MS/s for individual channels and 1.00 MS/s across multiple channels. The timing resolution is 10 ns, complemented by a timing accuracy of 50 ppm, ensuring precision in data collection. The USB-6353 is equipped with an analog trigger that supports various triggering functions, offering ±Full scale for AI<0.31> and ±10 Volts for APFI<0.1>. This trigger operates with 16 bits of resolution and is configured primarily for analog edge triggering, featuring an input resistance of 10 kΩ. Protection values for the device are rated at ±30 V in the 'on' state and ±15 V in the 'off' state, enhancing reliability. In addition to its input capabilities, the USB-6353 has four analog output channels, also with 16 bits of resolution, which facilitate the conversion of digital signals to analog outputs with a low output resistance of 0.2Ω and a current drive capability of ±5 mA. These channels can operate in various modes, including the frequently used Periodic Waveform Regeneration mode for generating consistent waveforms. The device is housed in a compact form factor measuring 10.4 × 6.8 × 1.4 inches (26.4 × 17.3 × 3.6 cm) and weighs approximately 3 lb 2 oz (1.42 kg), making it suitable for various applications in controlled environments, with an operating temperature range of 0 to 45 °C and storage capabilities from -40 to 70 °C. The USB-6353 features 128 screw terminals for efficient connectivity, and is backed by a 2-3 year warranty. For additional operational details, user manuals and maintenance guides are available for download. Pricing information can be acquired through a National Instruments sales representative.
