System compatibility

PCI-4454 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,audio test and frequency response measurement in legacy test systems.It is spare part for legacy test equipment overhaul.

Function

PCI-4454 is high-performance DSA board with 4 synchronized analog inputs and 2 analog outputs.It supports IEPE accelerometer and microphone sensors,built-in anti-aliasing filter suppresses signal aliasing.Simultaneous I/O enables stimulus-response testing.Self-calibration function maintains long-term measurement precision,multi-card synchronization for large-scale multi-channel test.

Installation

Insert PCI-4454 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 I/O connector

‑PCI gold finger edge connector

‑Board status indicator

Feature

PCI-4454 classic NI stimulus-response DSA board.Typical faults:50pin connector pin oxidation,IEPE excitation circuit failure,ADC/DAC measurement drift.Inspect sensor wiring and stimulus-response test before replacement.

Diagnostic

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

Product Brief

PCI-4454 is NI PCI bus DSA board with 4 synchronized AI and 2 AO,16-bit resolution and max 51.2kS/s sampling rate,supporting IEPE and self-calibration,for vibration,acoustic and audio stimulus-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.
