Description
Bently 3500/02 (129133‑02)
- Key Features: 14‑slot full‑size rack mechanical layout; 19‑inch EIA standard installation compatible; updated‑revision multi‑layer back‑plane bus supporting new‑generation M‑series monitor modules; supports rail‑mount, panel‑mount and bulkhead‑mount installation styles; integrated metal electromagnetic‑shielding chassis; full hot‑swap support for all plug‑in modules; dedicated dual‑power‑supply slots on far‑left position.
- Technical Specifications & Performance Parameters
- Total module slots: 14 slots
- Installation standard: 19‑inch EIA
- Operating temperature: 0 ℃ ~ +60 ℃
- Storage temperature: ‑40 ℃ ~ +85 ℃
- Weight: 7.9 kg
- Material Composition: Powder‑coated cold‑rolled steel chassis housing; updated‑revision multilayer FR‑4 back‑plane bus PCB; gold‑plated module receptacle contacts; reinforced aluminum alloy module guide rails; metal shielding partition components; complete installation mounting hardware set.
- Structural Features: Same outer mechanical dimension as 3500/01 chassis; front‑side module insertion guide‑rail structure; rear‑side space for external I/O termination modules; far‑left two slots reserved for redundant power‑supply modules; internal updated‑revision back‑plane bus board implements power distribution and inter‑module high‑speed communication.
- Working Principle: Chassis provides mechanical fixation and positioning for all plug‑in modules. Internal back‑plane board distributes power‑supply output to every module slot. Back‑plane high‑speed parallel bus completes bidirectional data exchange among power‑supply, monitor, communication gateway and relay modules, transmits measurement data, alarm flags and configuration instructions across whole rack system. Updated back‑plane circuit improves signal integrity for high‑speed M‑series module communication.
- Application Scenarios: New‑project 3500 TSI system main chassis for steam‑turbine and compressor units; system retrofit requiring compatibility with M‑series enhanced monitor modules; petrochemical and power‑plant rotating‑machinery protection cabinet assembly; spare‑part replacement for existing 3500/02 rack chassis hardware.
- Installation Requirements: Secure rack chassis firmly onto cabinet mounting rails or panel‑mount bracket; ensure good protective‑earth grounding for metal chassis; maintain sufficient rear‑side wiring and service clearance; guarantee surrounding ventilation for heat dissipation; install power‑supply modules into dedicated left‑side slots before loading other functional modules.
- Usage Notes: Ensure protective‑ground connection remains intact all the time; avoid violent module insertion which may damage back‑plane gold‑plated contacts; keep rack internal free of heavy dust and oil‑mist contamination; verify firmware compatibility between inserted monitor modules and chassis back‑plane revision; inspect back‑plane connector condition during major overhaul work.
