Description
Bently 3500/01 (129133‑01)
- Key Features: 14 module slot full‑size rack structure; 19‑inch EIA standard rail‑mount compatible; integrated high‑reliability multi‑layer back‑plane bus board; dedicated left‑side slots reserved for dual redundant power‑supply modules; supports rack‑rail mounting, panel‑cutout mounting and bulkhead mounting installation modes; metal shielding chassis reduces external electromagnetic interference; supports hot‑swap for all plug‑in modules without system shutdown; complies with API‑670 mechanical requirements for machinery‑protection racks.
- Technical Specifications & Performance Parameters
- Total available module slots: 14 slots
- Installation standard: 19‑inch EIA cabinet rail
- Operating temperature: 0 ℃ ~ +60 ℃
- Storage temperature: ‑40 ℃ ~ +85 ℃
- Back‑plane bus communication rate: dedicated parallel high‑speed system bus
- Weight: 7.8 kg
- Material Composition: Heavy‑duty cold‑rolled steel metal chassis shell with anti‑corrosion powder‑coating finish; multilayer FR‑4 back‑plane bus printed‑circuit board; gold‑plated module edge‑connector receptacles; reinforced aluminum alloy guide rails for module insertion; metal shielding partition plates; steel‑material mounting hardware kit.
- Structural Features: Rectangular metal cabinet‑style chassis; front side with module insertion guide rails for plug‑in modules; rear side accommodates all external I/O termination modules; internal multi‑layer back‑plane bus board distributes power supply and system communication signal for every slot; far‑left two slots exclusively reserved for redundant power‑supply modules; multiple mounting holes for three different installation styles.
- Working Principle: Rack chassis provides mechanical positioning and physical support for all plug‑in functional modules. Internal back‑plane bus board distributes regulated power supply from power‑supply modules to every slot. Back‑plane bus implements high‑speed parallel data communication between all inserted modules, completes measurement‑data exchange, alarm‑status transmission and configuration‑command forwarding among different functional modules.
- Application Scenarios: Main chassis platform for large‑scale steam‑turbine, gas‑turbine and centrifugal‑compressor 3500 TSI machinery‑protection system; petrochemical complex and thermal‑power‑plant rotating‑machinery monitoring cabinet; project upgrade and spare‑part replacement for existing 3500 full‑size rack systems.
- Installation Requirements: Fix rack chassis firmly onto 19‑inch cabinet guide rails or panel‑cutout mounting bracket; guarantee sufficient rear‑side service space for I/O modules and field‑wiring routing; ensure rack chassis reliable protective earth ground connection; reserve proper ventilation clearance around rack for heat dissipation; install power‑supply modules into dedicated far‑left slots before inserting other functional modules.
- Usage Notes: Strictly implement reliable protective‑ground connection for rack metal chassis; prohibit physical impact and deformation to back‑plane board during module insertion; maintain cabinet ventilation environment to avoid excessive operating temperature; prevent conductive dust and oil‑mist accumulation inside rack chassis; perform visual inspection of back‑plane connector gold‑plated contacts during major equipment overhaul cycles.
