The National Instruments USB-6366 is a high-performance multifunction I/O device designed for a variety of applications, including industrial automation, test automation, and data logging. This device features eight differential analog input channels with a 16-bit resolution that guarantees no missing codes, supporting sample rates up to 2 MS/s per channel. It provides multiple input ranges of ±1 V, ±2 V, ±5 V, and ±10 V, combined with a high input impedance of greater than 100 GΩ when powered on and 2 kΩ when powered off. The USB-6366 also includes two 16-bit analog output channels capable of a maximum update rate of 3.3 MS/s per channel, designed for low output impedance at 0.4 Ω and equipped with ±25 V overdrive protection.

For digital interfacing, the device is equipped with 24 digital I/O lines and four 32-bit general-purpose counters/timers, facilitating precise timing and control operations. Utilizing NI-STC3 onboard timing technology, it offers advanced synchronization features and an analog input bandwidth of 3.4 MHz, with various triggering modes such as analog edge and analog window triggering. The device has built-in overvoltage protection of ±36 V when powered on and ±15 V when powered off for its analog input channels, enhancing its reliability in demanding environments. Additionally, it supports USB Signal Stream and programmed I/O data transfer modes for high-speed, accurate data acquisition. The USB-6366 is delivered with NI-DAQmx software for streamlined configuration and measurement, and it meets safety standards including CSA, EN, UL, and IEC 61010-1. Available in multiple connector types such as BNC, mass termination, or screw terminals, the USB-6366 serves as a versatile, high-precision solution tailored for complex applications.
