System compatibility

PCI-4461 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 acoustic test,shock & vibration measurement,stimulus-response test and machine condition monitoring in legacy test systems.It is spare part for legacy test equipment overhaul.

Function

PCI-4461 is high-performance 2AI/2AO DSA board for sound and vibration shturl.cc/ supports IEPE accelerometers and microphones,TEDS auto sensor recognition.2 input and 2 output channels run synchronously for stimulus-response testing.Digital anti-aliasing filter removes aliasing noise.Multi-card synchronization supports large-channel vibration measurement systems.

Installation

Insert PCI-4461 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 I/O connectors

‑PCI gold finger edge connector

‑Board status indicator

Feature

PCI-4461 classic NI high-end sound & vibration DSA board.Typical faults:BNC connector oxidation,IEPE excitation circuit damage,ADC/DAC measurement drift.Inspect sensor wiring and spectrum test before replacement.

Diagnostic

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

Product Brief

PCI-4461 is NI PCI bus 24-bit DSA board with 2 synchronized AI and 2 AO,max 204.8kS/s sampling rate,supporting IEPE and TEDS,for acoustic,shock vibration and 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.
