The National Instruments PXI-4224 is a highly sophisticated PXI Analog Input Module designed for precise analog data acquisition in industrial applications. With part numbers 779182-01 and 191288F-02, this module features channel-to-channel isolation that ensures accurate measurements even in the presence of high common-mode voltages, making it ideal for applications such as thermocouple measurements, multichannel data logging, and testing of fuel cells and batteries. The PXI-4224 supports 60 VDC (42 Vrms) isolation between channels and provides programmable gain settings to enhance measurement accuracy across its eight differential analog input channels. It achieves a maximum sample rate of 200 kS/s with a 16-bit resolution over a ±10 VDC input range.

The module connects easily via a 25-pin D-SUB connector and an SMB connector, with each set of screw terminals clearly marked to correspond with their respective differential input signals. For enhanced integration, users can utilize the TB-2725 terminal block specifically designed for the PXI-4224 or create a customized connector using the 25-pin D-SUB interface. The design also allows for effective noise reduction through shielding of field wiring, addressing common challenges associated with ground potential differences. Although the PXI-4224 has been designated as obsolete by National Instruments, it remains available for purchase and repair through Apex Waves. This module is backed by a three-year warranty, and comprehensive user and maintenance manuals can be downloaded for further guidance in setup and application.
