System compatibility

PCI-4452 belongs to NI DSA dynamic signal acquisition platform.It works with standard PCI industrial PC,supported by NI-DAQmx driver and LabVIEW,widely used for multi-channel vibration,acoustic noise,shock and frequency response measurement in legacy test systems.It is spare part for legacy test equipment overhaul.

Function

PCI-4452 is high-performance 4-channel DSA board for dynamic signal measurement.It supplies IEPE power for accelerometer and microphone sensors,with built-in anti-aliasing filter to eliminate aliasing interference.Four channels sample synchronously for multi-point FFT spectrum analysis.Multi-card synchronization supports large-scale vibration test setup.

Installation

Insert PCI-4452 into computer PCI slot and fasten bracket.Connect sensors to 50pin shielded terminal block.Install NI-DAQmx driver.Take ESD protection before installation.

Interface

‑50-pin multi-function analog & digital I/O connector

‑PCI gold finger edge connector

‑Board status indicator

Feature

PCI-4452 classic NI 4-channel dynamic signal acquisition board.Typical faults:50pin connector pin oxidation,IEPE excitation circuit failure,ADC measurement drift.Inspect sensor wiring and spectrum test before replacement.

Diagnostic

Fault phenomenon:no signal input,high noise,channel inconsistency.Check shielded sensor cable,transducer,PCI slot contact,NI-DAQmx driver and coupling/IEPE parameter configuration.

Product Brief

PCI-4452 is NI PCI bus 4-channel 24-bit DSA board with max 51.2kS/s simultaneous sampling and IEPE excitation,for multi-channel vibration,acoustic and frequency response testing and legacy dynamic test equipment renovation.Mainly used for maintenance and replacement of old test equipment.ESD protection must be followed during handling.
