The National Instruments part number 777676-01, commonly known as the PXI-6071E, is a versatile PXI Multifunction I/O Module specifically engineered to meet the diverse needs of applications in research, design verification and testing, industrial testing, and laboratory automation. This module features extensive analog and digital input/output capabilities, along with two 24-bit counters and timers, which deliver reliable data acquisition performance across a wide array of tasks. The integrated NI-DAQmx driver and configuration utility streamline both setup and measurement processes, enhancing user experience.

Centralizing timing functionality, the PXI-6071E utilizes the National Instruments DAQ system timing controller (DAQ-STC), which encompasses multiple timing groups tailored for applications including general-purpose counter/timer operations, analog input, and analog output. Users can configure these timing groups independently to meet specific needs, offering three 24-bit and one 16-bit counters for analog output, two 24-bit counters for general tasks, and two 24-bit plus two 16-bit counters for analog input. Additionally, the device supports both buffered and non-buffered operations while allowing seamless integration of external timing and triggering signals via PFI lines.

Enhancements for sensor and high-voltage measurements are facilitated by compatibility with SCC or SCXI signal conditioning modules. The modular architecture permits expansion up to 3,072 channels, making it particularly beneficial for large measurement systems that require high-speed data acquisition. With a bandwidth capable of 333 kHz, this multifunction I/O module supports 64 single-ended or 32 differential channels, with configurations selectable via software. The onboard analog-to-digital converter (ADC) employs a 12-bit successive approximation architecture, achieving a maximum sampling rate of 1.25 MS/s. The module boasts a relative accuracy of ±0.5 LSB (dithered) and ±1.5 LSB (undithered), alongside exceptional differential nonlinearity specifications. The minimal offset error ensures precision, with pre-calibration errors ranging from ±2.5 mV to ±100 mV, and post-calibration errors between ±12 μV and ±0.5 mV for pregain and postgain, respectively.

The PXI-6071E is an essential component for professionals requiring a robust solution for multifunction data acquisition and control tasks.
