National Instruments USB-6341

The National Instruments USB-6341 is a versatile multifunction data acquisition device designed for industrial automation applications. This device features four 32-bit counters/timers and supports both digital and analog I/O, making it ideal for a variety of tasks such as test automation, control, and data logging. It accommodates up to 16 single-ended or 8 differential analog input channels, achieving a maximum sampling rate of 500 kSamples/s with 16-bit resolution, ensuring high precision in measurements through its NI-STC3 technology, which enables independent timing for analog and digital signals. The USB-6341 also offers two analog output channels, with an impressive update rate of 900 kSamples/s and 16-bit resolution, catering to applications requiring precise control over output signals with low impedance and inherent overdrive protection.

The device includes 24 digital I/O channels that can be configured as either input or output. Additionally, the four integrated 32-bit counters/timers enable functionality such as edge counting, pulse width measurement, and quadrature encoding, with multiple input routing options and synchronization capabilities with external signals. The USB-6341 operates with USB 2.0 Hi-Speed or full-speed connections, facilitating fast data transfer rates for efficient communication with host computers. It is available in two connector variants: a BNC option (part number 782251-01) featuring twenty BNC connectors, and a screw terminal option (part number 781438-01) with thirty terminals, each designed with durable enclosures suitable for industrial environments. The board-only versions (part numbers 782250-01 and 782254-01) provide distinct sampling rates of 500 kS/s and 2 mS/s.

Dimensions for the screw terminal model are 10.4 × 6.8 × 1.4 inches and weight is 3 lb 1.6 oz, while the BNC model measures 8.0 × 7.3 × 2.7 inches and weighs 3 lb 5.6 oz. The USB-6341 is backed by a three-year warranty, and the comprehensive user and maintenance manuals are available for download. Please contact a sales representative for pricing information.
