National Instruments 778627-01

The National Instruments 778627-01, commonly known as the PCI-6014, is a multifunction I/O device engineered for high-performance applications encompassing analog, digital, and timing inputs and outputs. This versatile device features 16 channels of 16-bit analog input, two channels of 16-bit analog output, and eight digital I/O lines, making it ideal for research, design verification, laboratory automation, and industrial testing. The device employs the NI data acquisition system timing controller (DAQ-STC) to ensure seamless integration and dependable performance for time-sensitive applications.

The PCI-6014 is equipped with advanced capabilities, including two 24-bit counters with digital triggering, in addition to its I/O functionality. It utilizes a 68-pin connector and supports two software-configurable modes for analog input: differential mode (with eight channels) and nonreferenced single-ended mode (with up to 16 channels). Scanning configurations can be tailored to specific requirements, allowing combinations such as 12 channels, of which four can function differentially and eight non-referenced. The A/D converter allows for optimization of resolution through programmable gain settings (0.5, 1.0, 10, or 100), enhancing measurement accuracy.

With its flexibility, each digital I/O line can be independently configured for input or output via software, and all ports begin in a high-impedance state upon startup and reset, offering increased adaptability for various applications. The included NI-DAQmx driver and configuration tool automate the setup process and streamline measurement workflows. The DAQ-STC timing controller encompasses three timing groups that oversee analog output, general-purpose counters/timers, and analog input operations, achieving a maximum timing resolution of 50 ns. This comprehensive capability supports a range of sophisticated applications, including buffered pulse generation and equivalent time sampling, with a maximum sampling rate of 200 kS/s and programmable input range for bipolar signals.
