The NI PXI-4220 is a high-performance, 2-channel bridge input module designed for use with SCXI & Legacy systems. With a part number of 778745-4220, this module offers precision measurement capabilities for a variety of sensor types. It is specifically designed to work with Full-, Quarter-, and Half-Bridge Sensors, making it highly versatile for different measurement needs.
The PXI-4220 features a 16-Bit resolution and can achieve a maximum sampling rate of 333 kS/s, ensuring high accuracy and fast data acquisition rates. This module allows for excitation voltage adjustment via pins 2 and 7, which can be software-adjustable, providing flexibility for various measurement setups.
Equipped with multiple lowpass filter cutoff frequency options, including 10 or 100 Hz, 1 kHz or 10 kHz, and the ability to disable the filter, users can tailor their signal processing requirements precisely. Each channel incorporates a 4-pole Butterworth filter, optimizing signal integrity and measurement accuracy.
The PXI-4220 operates with either an external (PXI Trigger Bus) or internal (20 MHz) time base, offering versatility in synchronization and timing. The module also supports 1 x Star Trigger and 6 x Trigger Lines on the PXI Trigger Bus, enhancing its integration capabilities within complex test systems.
This module boasts an amplifier input impedance of greater than 1 GΩ DC and maintains an input bias current of ±20 nA max, ensuring high fidelity for sensitive measurements. Compatibility with NIDAQmx Driver Software (Version 7.0 or later) and programming environments such as LabVIEW, LabWindows/CVI, and Measurement Studio offers a seamless software experience for users.
The physical dimensions of the PXI-4220 are 6.3 x 3.9 x 0.79 inches, making it compact and suitable for integration into a variety of PXI chassis configurations.
