National Instruments PXI-6123 Multifunction I/O Module

The National Instruments PXI-6123 (Part number: 779181-01) Multifunction I/O Module has several types of channels, including eight analog input channels, eight DIO channels, and two up/down counters, and does not contain any analog output channels. This module also has a maximum sample rate of 500 kS/s per channel, 16-bit resolution, and an absolute accuracy of 4.96 mV at the ±10 V range. The suggested warm-up time for maximum performance is 15 minutes. There is a two-year calibration interval, with specifications guaranteed for that time period. The self-calibration process is straightforward using NI-DAQmx, which compensates for nonlinearity, offset, and gain errors in the module. The self-calibration process is completed in mere seconds. This module has I/O customization options, NI-STC3 timing technology, the capability to stream information over the PXI bus, and programmable input gains to maximize resolution.

The PXI-6123 Multifunction I/O Module includes a powerful NI-DAQmx driver, with an API that works seamlessly with various development options, such as C, C#, Python, LabVIEW, and more. This integration offers high performance and an effortless experience, eliminating the need for manual function wrapping. The NI-DAQmx driver API is used across all NI DAQ models, ensuring broad compatibility and reducing the need for redevelopment when upgrading hardware. Additionally, the NI-DAQmx driver provides access to extensive help documentation, resources, and ready-to-run example programs, which can serve as starting points for user applications.

The PXI-6123 has reached Mature Status, meaning it remains available for purchase and repairs through Apex Waves but is not recommended for new designs.
