Description
The National Instruments PXI-4220 PXI Strain/Bridge Input Module, with part number 778745-4220, is a high-resolution 16-Bit, 2-Channel device capable of a sampling rate up to 333 kS/s. Each channel features 9-pin, D-SUB connectors, facilitating easy and secure connectivity. This module is highly adaptable, offering programmable excitation, bridge configuration, filtering, and amplification for each channel, ensuring versatile use across a range of applications.
Embedded within the module is a 4-pole Butterworth filter per channel, with software-selectable cutoff frequencies including 10 Hz, 100 Hz, 1 kHz, and 10 kHz, which provide users with the flexibility to tailor signal processing to their specific needs. The PXI-4220 can synchronize with an external time base via the PXI trigger bus or utilize its own internal 20 MHz master time base for precise timing operations.
It includes a PXI trigger bus that comprises 1 x star trigger and 6 x trigger lines, which are essential for coordinating multi-device synchronization. The module’s amplifier boasts a significant >1 G DC input impedance and ±20 nA max input bias current, providing reliable and accurate amplification of the input signal. Compatible with NIDAQmx driver software (version 7.0 or later), it integrates seamlessly with popular application development environments (ADEs) like LabVIEW, LabWindows/CVI, and Measurement Studio, enhancing the development experience.
