National Instruments 779113-01 PXI Multifunction I/O Module
The National Instruments 779113-01 (PXI-6221) is a multifunction PXI data acquisition module from the M Series, designed for a wide range of measurement, control, and automated test applications. The module provides 16 analog input channels that can be configured as either 16 single-ended or 8 differential inputs, with 16-bit resolution and an aggregate sampling rate of up to 250 kS/s. It update rates of up to 833 kS/s per channel. For digital control and timing applications, the 779113-01 provides 24 bidirectional digital I/O lines, eight of which can be clocked at up to 1 MHz for synchronized digital operations. Two 32-bit counters/timers and additional digital triggering capabilities provide further flexibility for automation and measurement systems.
The analog input section supports software-selectable voltage ranges of ±0.2 V, ±1 V, ±5 V, and ±10 V, allowing the module to accommodate signals with different amplitude requirements. The digital I/O can also be used for correlated operations, with the clocked lines supporting synchronized data transfer and digital waveform generation. These features make the part suitable for applications including data logging, machine and process control, laboratory automation, research and development, and design verification testing.
The module can be integrated with compatible signal-conditioning hardware, including SCC and SCXI systems, to expand its measurement capabilities for sensor signals and other specialized inputs. This flexibility makes the 779113-01 suitable for a variety of industrial and laboratory test configurations where multiple types of signals need to be measured or controlled from a single PXI-based platform.
The 779113-01 is supported by National Instruments NI-DAQmx driver software, which provides configuration, measurement, and hardware-control functions for data acquisition applications. NI-DAQmx integrates with development environments such as LabVIEW, LabWindows/CVI, and Measurement Studio, allowing users to develop custom measurement and control applications. The module incorporates National Instruments technologies including NI-STC 2 system controller technology, NI-PGIA 2 programmable gain instrumentation amplifier technology, and NI-MCal calibration technology to support measurement accuracy and system performance.
The Multifunction I/O Module provides a combination of analog input and output, digital I/O, counters/timers, triggering, and signal-conditioning support in a single PXI module. Its flexible I/O configuration and compatibility with the NI-DAQmx software environment make it a practical choice for automated test, data acquisition, control, and laboratory measurement systems.
