National Instruments PXI-6259 PXI Multifunction I/O Module
Featured with 16 differential or 32 single-ended Analog Input channels (16-Bit, 1.25 MS per second), 48 Digital I/O channels, and 4 Analog Output channels, the National Instruments PXI-6259 (Part Number: 779632-01, 191325F-01L) is a Multifunction I/O Module. This module has correlated digital I/O, two 32-bit timers/counters, analog I/O, and more. It is a low-cost yet effective module with robust DAQ capabilities for a broad range of applications. With SCXI or SCC signal conditioning modules, the user can also add a sensor and HV measurement capability to their PXI-6259. The NI-DAQmx driver software can be used with the NI PXI-6259 to keep the measurement and configuration process simple.
The PXI-6259 is a promising solution with a timing accuracy up to 50 ppm for the sample state. For improving measurement accuracy, this module has NI-MCal calibration technology. Additionally, this module comes with 6 DMA channels to provide high-speed data throughput. The NI PXI-6259 comes with an onboard, integrated NI-PGIA 2 amplifier, which is designed to operate with fast settling times at high rates of scanning while ensuring 16-bit accuracy. With this Multifunction I/O Module, the user will be able to achieve analog as well as digital triggering.
This module comes with seven programmable input ranges/channel and up to 48 digital I/O lines. This PXI Multifunction I/O Module can facilitate X1, X2, or X4 Quadrature Encoder Inputs as well. The PXI-6259 offers ±11 V of AI GND maximum operating voltage for analog signals. While in the “On” state, the input impedance remains >10 GΩ in parallel with 100 pF (AI+ to AI GND) and (AI- to AI GND). This module has a timing resolution of 50 ns.
The NI-DAQmx driver software can be used with the NI PXI-6259 to keep the measurement and configuration process simple. Additionally, the software can be configured using the Measurement & Automation Explorer (MAX) tool. The software is compatible with application development environments (ADEs) such as LabVIEW, LabWindows, and Measurement Studio. The device is equipped with a 68-pin shielded connector block.
The PXI-6259 is now regarded as Obsolete and is no longer available direct from the manufacturer National Instruments, but the PXI Multifunction Module will still be available for purchase and repairs with Apex Waves in perpetuity.
