System compatibility

PCI-4351 belongs to NI high precision DAQ platform.It works with standard PCI industrial PC,driven by Traditional NI-DAQ legacy driver,supported by LabVIEW and LabWindows/CVI,widely used for RTD temperature sampling,low-level voltage and resistance measurement in industrial thermal test systems.It is spare part for legacy test equipment overhaul.

Function

PCI-4351 is 24-bit high precision DAQ board dedicated for temperature and low voltage measurement.It supplies constant current source for RTD and thermistor sensors,supports 4-wire resistance measurement to eliminate lead resistance error.Multi-channel sequential scanning and hardware trigger realize synchronous multi-point temperature acquisition.

Installation

Insert PCI-4351 into computer PCI slot and fasten bracket.Connect sensor wiring to 68pin shielded terminal block.Install Traditional NI-DAQ driver.Take ESD protection before installation.

Interface

‑68-pin multi-function analog I/O connector

‑PCI gold finger edge connector

‑Board status indicator

Feature

PCI-4351 classic NI high precision temperature DAQ board.Typical faults:68pin connector pin oxidation,ADC measurement drift,constant current source failure.Inspect sensor wiring and calibration status before replacement.

Diagnostic

Fault phenomenon:abnormal temperature reading,unstable voltage measurement,channel no response.Check shielded sensor cable,PCI slot contact,legacy NI-DAQ driver and RTD wiring configuration.

Product Brief

PCI-4351 is NI PCI bus 24-bit high precision DAQ board with 8 differential channels,supporting RTD,thermistor and 4-wire resistance measurement,for multi-point temperature monitoring and legacy thermal test equipment renovation.Mainly used for maintenance and replacement of old test equipment.ESD protection must be followed during handling.
