Functional Features Acquires vibration sensor dynamic analog signals. Completes high‑speed signal sampling and digital processing. Uploads dynamic measurement data to system host. Front‑panel LED indicates signal receiving and module fault status. Built‑in hardware self‑diagnosis detects sensor loop abnormality.
Application Scenarios Mechanical condition monitoring spare part. Widely used for turbine, fan and pump vibration monitoring system maintenance in power and petrochemical industry.
Performance Parameters High‑speed high‑precision dynamic signal sampling capability. Effective galvanic isolation suppresses site interference. Accurate sensor loop fault detection.
Material Composition Flame‑retardant plastic module housing. Multilayer glass‑fiber epoxy printed circuit board. High‑speed sampling and signal conditioning assemblies. Back‑plane plug‑in connector and sensor wiring terminals.
Structural Characteristics Standard rack‑mount plug‑in module. Front side with sensor signal terminals and status LED indicators. Rear side equipped with back‑plane bus connector. Weight approximately 0.44 kilogram.
Working Principle Vibration dynamic signal from field sensor enters module through front‑end terminals. Internal high‑speed sampling circuit converts analog dynamic signal into digital data. Processed data is uploaded to monitoring host via back‑plane bus. Diagnosis circuit continuously monitors each sensor channel loop condition.
Installation Requirements Disconnect rack auxiliary power before replacement. Insert 1440‑DYN02‑01RJ into designated rack slot and lock fixing latch. Complete sensor shielded cable wiring on front‑end terminals. Ensure back‑plane connector is fully engaged. Restore power supply, perform channel calibration and verify vibration data acquisition.
Usage Notes Deploy dedicated shielded low‑noise cables for vibration sensors. Separate sensor cables from high‑power cables. Check terminal fastening status in regular maintenance. Avoid dusty and condensing operating environment.
