Part Number: 777636-01
The National Instruments 777636-01, commonly known as the PXI-6031, is a high-performance PXI Multifunction I/O Module designed for a diverse range of applications, including research, design verification, laboratory automation, and factory testing. This versatile module features 64 analog input channels, which can be configured as either single-ended or differential, alongside 2 analog output channels and 8 digital I/O channels, making it well-suited for various data acquisition tasks. The device is equipped with two 24-bit counters, ideal for general-purpose counting and timing applications.

For optimal performance, the 777636-01 utilizes the National Instruments DAQ system timing controller (DAQ-STC) to manage time-sensitive operations. This integrated timing controller enhances functionality by supporting multiple timing resolutions, allowing for operations such as buffered waveform acquisition and generation, as well as non-buffered digital operations. The accompanying NI-DAQmx driver simplifies configuration and measurement, fostering efficient system integration.

The module's analog inputs utilize a 16-bit successive approximation A/D converter (ADC) with a maximum sampling rate of 100 kS/s, capable of operating within a voltage range of ±11 V and offering overvoltage protection of up to ±25 V when powered on. The analog outputs employ a 16-bit double-buffered digital-to-analog converter (DAC) with a maximum update rate of 100 kS/s, featuring a selectable voltage range of ±10 V or 0 to 10 V, with an output impedance of 0.1 Ω and a current drive capacity of ±5 mA. Additionally, the module supports eight 5 V TTL/CMOS-compatible digital I/O channels, enhancing its digital interfacing capabilities.

The versatility of the 777636-01 extends to its compatibility with SCC or SCXI signal conditioning modules, providing efficient signal conditioning and switching within a robust chassis designed for multiplexing, amplification, filtering, and isolation of analog signals from various transducers. This multifunctional I/O module represents an ideal solution for complex measurement and control tasks across multiple industrial and laboratory environments.
