Part Code Definition

A6500-UM = Universal Measurement Card for AMS6500 ATG series; no suffix variant, cooperate with A6500-LC for LVDT signal conversion, incompatible with old IMR6000/IMR6500 rack of classic AMS6500.

Technical Specifications

Backplane supply:24VDC from A6500-SR rack backplane, power consumption ≤4.8W

Input channel:2 fully independent configurable measuring channels, switchable sensor excitation source onboard

Supported transducers:eddy-current proximity probe, piezoelectric accelerometer/velometer, seismic pickup, Hall-effect keyphasor, LF low-frequency bearing vibration, LVDT(with A6500-LC accessory)

Measuring items:shaft relative vibration, casing absolute vibration, axial thrust displacement, shaft eccentricity, rotating speed, cylinder expansion, steam valve stem opening

Analog output:isolated 4~20mA/0~10VDC per channel for DCS remote indication

Digital port:5DI+6DO dry contact, DI for external interlock signal, DO for alert/trip relay output

Isolation grade:1500VAC between field signal and internal rack bus

Ambient:operating -20℃~+70℃, storage -40℃~+85℃, RH5%~95% non-condensing

Dimension:3HE×6TE(30×128×162mm), net weight≈0.2kg

Interface & Communication Layout

Front panel:2 SMB sensor input sockets; RUN/ALARM/TRIP status LED indicators

Rear golden finger:dedicated A6500 internal RS485 backplane bus, upload all measured data & fault codes to A6500-CC communication module

Rear terminal strip:4~20mA analog output terminals + all DI/DO wiring terminals for site interlock connection

System communication:data converted into Modbus RTU/TCP via A6500-CC to upper DCS/SCADA

Core Functions

Universal channel configuration:each channel independently set to vibration/displacement/speed/position mode via PC configuration software, flexible on-site modification without card replacement

Full-range machine protection:programmable Alert/Danger threshold, independent trip logic for each measuring parameter, sensor open/short-circuit auto-diagnosis with fault flag upload

PeakVue bearing fault detection built-in for early rolling element bearing deterioration warning

Hot swap maintenance:plug/unplug online without rack power-off, residual channels keep continuous monitoring during single-card replacement

Real-time data forwarding:transmit instantaneous value, alarm status, historical peak data to communication card for upper system acquisition

Application Scenarios

New-built steam/gas turbine, petrochemical large centrifugal compressor AMS6500 ATG protection cabinet; old unit classic AMS6500 system upgrade reconstruction, multi-parameter mixed monitoring cabinet space optimization retrofit.

Operation & Maintenance Notes

Only mount into dedicated A6500-SR rack slot; confirm matching sensor type before parameter setup; separate sensor shield cable from high-current power cable to avoid EMI interference; complete channel range & alarm threshold debugging via official configuration software after field wiring; periodically inspect front panel lamp state and DCS online data during regular unit overhaul.
