Bently Nevada 3500/20 Compatible products
Core system components: Bently Nevada 3500/20 is used with 3500/05 rack, 3500/15 redundant power supply (such as 114M5335-01), and relies on 3500/92 communication gateway to connect to DCS or System 1* software.
Monitoring and execution module: Supports vibration monitoring module (such as 3500/42M), overspeed protection module (3500/53), relay module (3500/32), and realizes multi-rack cascading through RS422 interface.
Upper system integration: Connect TDXnet, DDIX communication processor through I/O module, or directly connect to Bently Nevada Transient Data Interface (TDI) for dynamic data analysis.
Bently Nevada 3500/20 Key Features
Dual-mode security lock and flexible configuration:
The physical key lock of Bently Nevada 3500/20 supports RUN (lock configuration) and PROGRAM (allow remote configuration) dual modes to prevent unauthorized modification; 63 addressable addresses support multi-rack expansion to meet the distributed monitoring needs of large factories.
Triple redundancy (TMR) support:
TMR version (such as 125744-01) adds "monitor channel comparison" in addition to standard functions, real-time comparison of three redundant monitor outputs, triggering system event list when abnormal, and improving fault tolerance in high-risk scenarios such as nuclear power plants.
