National Instruments 782264-01 Multifunction I/O Module

The part number 782264-01 from National Instruments is the identifying part number for the USB-6366 Multifunction I/O Module. The 782264-01 features 8 differential analog input channels, each with a 16-bit analog-to-digital converter (ADC). This high resolution ensures precise measurements. The device supports a maximum sample rate of 2 MS/s per channel, which is ideal for capturing fast transient signals. The input range is adjustable, offering ±1 V, ±2 V, ±5 V, and ±10 V to accommodate various signal levels. The device ensures high input impedance (>100 GΩ in parallel with 100 pF when powered on) and an excellent common-mode rejection ratio (CMRR) of 75 dB at 60 Hz. 

The 782264-01 Multifunction I/O Module includes 2 analog output channels with 16-bit resolution, capable of generating signals at a maximum update rate of 3.3 MS/s per channel. The output range is configurable up to ±10 V, providing versatility for signal generation tasks. The output channels have a low output impedance of 0.4 Ω and can drive currents up to ±5 mA. This module offers 24 digital I/O lines, which are individually programmable as inputs or outputs. These lines support TTL/CMOS logic levels and include built-in pull-down resistors to ensure defined logic states. The digital lines support waveform generation and acquisition with FIFO sizes of 2,047 samples for digital output and 255 samples for digital input. The 782264-01 also includes four 32-bit general-purpose counters/timers for precise timing and event-counting operations.

This module provides extensive triggering capabilities, including analog and digital triggers. It supports analog edge triggering, analog edge triggering with hysteresis, and analog window triggering, with a resolution of 16 bits. The device features one analog trigger source and multiple digital trigger sources, including PFI lines and internal signals. These triggers enhance the flexibility and control over data acquisition processes.

The 782264-01 is designed for reliable operation in various environments. It operates within a temperature range of 0 °C to 45 °C and can be stored between -40 °C to 70 °C. The device is built to withstand operational shocks of up to 30 g peak and random vibrations up to 0.3 grms. It measures 26.4 cm x 17.3 cm x 3.6 cm and weighs approximately 1.428 kg for the screw terminal version.
