The National Instruments part number 782261-01 identifies the USB-6356, a high-performance USB Multifunction I/O Module designed for industrial applications. This versatile device incorporates a blend of analog input, analog output, digital input/output, and counter/timer capabilities, making it suitable for a wide range of control and monitoring tasks. The USB-6356 features eight analog input channels, each with 16-bit resolution and a maximum sampling rate of 1.25 MS/s, complemented by two analog output channels that also support 16-bit resolution for precise waveform generation. Additionally, the module provides 24 digital I/O channels and four 32-bit counters/timers for effective pulse-width modulation (PWM), pulse train generation, and encoder measurements.

Advanced timing and triggering functionalities are integral to the USB-6356, with a 32-bit resolution and multiple triggering modes designed to enhance system synchronization and data acquisition efficiency. The device can achieve a maximum sampling rate of 1.25 MS/s for analog inputs and 3.33 MS/s for digital I/O. It is compatible with various National Instruments software platforms, including LabVIEW, LabWindows/CVI, and Measurement Studio, and can be easily configured using the Measurement & Automation Explorer (MAX) tool. The device accepts DC-coupled inputs and provides selectable input ranges of ±0.2 V, ±1 V, ±5 V, and ±10 V, accommodating a maximum working voltage of ±11 V for analog inputs, factoring in both signal and common-mode voltages.

Data connectivity is facilitated by a standard USB 2.0 interface, supporting USB Signal Stream for continuous data transfer as well as programmed I/O for precise control. The module includes crucial triggering functions such as Start Trigger, Reference Trigger, Pause Trigger, Sample Clock, and Sample Clock Timebase, ensuring accurate control and synchronization in complex data acquisition tasks. The USB-6356 is connected via a 68-pin SCSI connector for robust I/O linkages, making it an indispensable tool in many industrial automation environments.
