System compatibility

PCI-6255 belongs to NI M Series multifunction DAQ platform.It works with standard PCI industrial PC,supported by NI-DAQmx and LabVIEW,widely used for ultra high-channel high-speed data acquisition,laboratory dynamic measurement,production line testing and transient signal capture.It is spare part for legacy test equipment overhaul.

Function

PCI-6255 is M-series ultra high-channel high speed multifunction PCI DAQ board.It integrates 80/40-ch analog input,2-channel analog output,24-channel digital I/O and 32-bit counter functions.16-bit ADC supports max 1.25MS/s single channel sampling.PFI lines support external timing and triggering for high-density high-speed automated test systems.

Installation

Insert PCI-6255 into PCI slot and fasten bracket.Connect signal wiring to dual 68pin VHDCI terminal block.Install NI-DAQmx driver.Take ESD protection before installation.

Interface

‑Dual 68-pin VHDCI multi-function I/O connector

‑PCI gold finger edge connector

‑Board status indicator

Feature

PCI-6255 classic NI M-series high density DAQ board.Typical faults:VHDCI connector pin oxidation,ADC reading drift,counter timing error.Inspect analog input and digital channel before replacement.

Diagnostic

Fault phenomenon:abnormal AI reading,no AO output,digital channel failure,counting error.Check sensor wiring,PCI slot contact,DAQ driver and channel configuration.
