System compatibility

PCI-4462 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 acoustic test,shock & vibration measurement,NVH analysis and machine condition monitoring in legacy test systems.It is spare part for legacy test equipment overhaul.

Function

PCI-4462 is high-performance 4-input DSA board dedicated to sound and vibration measurement.It supplies IEPE power for accelerometers and microphones,TEDS enables automatic sensor recognition.Four channels sample synchronously for FFT spectrum analysis.Digital anti-aliasing filter eliminates aliasing noise.Multi-card synchronization expands measurement channels for large-scale vibration test systems.

Installation

Insert PCI-4462 into computer PCI slot and fasten bracket.Connect sensors to BNC connectors.Install NI-DAQmx driver.Take ESD protection before installation.

Interface

‑4×BNC analog input connectors

‑PCI gold finger edge connector

‑Board status indicator

Feature

PCI-4462 classic NI 4-channel sound & vibration DSA board.Typical faults:BNC connector oxidation,IEPE excitation circuit damage,ADC measurement drift.Inspect sensor wiring and spectrum test before replacement.

Diagnostic

Fault phenomenon:no signal,high background noise,channel mismatch.Check BNC cable,transducer,PCI slot contact,NI-DAQmx driver and IEPE/TEDS configuration.

Product Brief

PCI-4462 is NI PCI bus 24-bit 4AI DSA board with max 204.8kS/s sampling rate,supporting IEPE and TEDS,for multi-channel acoustic,shock vibration and NVH testing and legacy dynamic test equipment renovation.Mainly used for maintenance and replacement of old test equipment.ESD protection must be followed during handling.
