- Agency approval: base version without extra hazardous‑area certification
- Material Composition: FR‑4 high‑Tg multilayer printed circuit board; industrial‑grade surface‑mount signal processing chips; gold‑plated backplane edge connector; metal module front panel with status LED indicators; metal shielding can for analog signal circuit; high‑strength plastic module locking mechanism.
- Structural Features: Full‑height plug‑in rack module structure; front panel equipped with multi‑color LED status indicators; rear side gold‑plated edge connector mates with 3500 rack backplane; internal metal shielding housing isolates analog signal circuit from digital noise; mechanical locking latch fixes module inside rack slot.
- Working Principle: Module internal circuit generates high‑frequency excitation signal and delivers to field proximity probe via backplane and I/O modules. It receives impedance‑variation feedback signal from transducer system, converts impedance change into digital displacement and vibration measurement values. It compares real‑time measured values against user‑configured Alert and Danger setpoints. Alarm status transmits to rack backplane bus for relay modules and upper communication modules.
- Application Scenarios: Radial shaft‑vibration protection for steam turbines and centrifugal compressors; thrust‑bearing axial‑position monitoring; rotor eccentricity measurement; differential expansion monitoring for large rotating machinery; petrochemical and power‑plant 3500 TSI machinery‑protection racks.
- Installation Requirements: Insert module into designated full‑height slot inside 3500 system rack; engage mechanical locking latch to secure module position; complete rack power‑off hot‑swap following official maintenance procedure; configure measurement parameters, alarm thresholds and transducer total length via 3500 rack configuration software; verify transducer wiring termination status on corresponding I/O module.
- Usage Notes: Do not plug or unplug module under full‑power hot‑swap without following official operating procedure; avoid static electricity discharge to circuit board components; strictly match configured total transducer system length with actual field probe plus extension‑cable total length; inspect front‑panel LED indicator status during daily equipment inspection; perform configuration backup after every parameter modification.
