3500/30 dedicated rack interface module

The BENTLY 3500/30 is a dedicated rack interface module (also known as a "Rack Communication & Control Module") for Bently Nevada’s 3500 Series Rotating Machinery Protection & Monitoring System. Unlike the single-frame-focused 3500/91 or multi-frame 3500/92, the 3500/30 is engineered as a centralized control and communication hub for large-scale, multi-rack 3500 systems (e.g., complex turbine trains, multi-compressor plants). It integrates advanced data aggregation, system-wide fault management, and third-party system integration capabilities—serving as the "brain" to coordinate multiple 3500/10 (single-frame) and 3500/20 (multi-frame) racks, ensuring unified monitoring and protection of critical rotating equipment. Below is its comprehensive detailed information:

I. Core Technical Parameters

Category	Specific Specifications
Basic Identification	- Model: 3500/30- Product Type: Multi-Rack Interface & Control Module- Applicable System: Bently 3500 Series (supports up to 16 interconnected 3500/10/20 racks)- Core Role: Centralized data aggregation, cross-rack communication, system-wide alarm management, and integration with upper-level DCS/SCADA/IoT platforms
Communication Capabilities	- Rack-to-Rack Communication:- Proprietary "3500 Link" protocol (via fiber optic/Ethernet); supports up to 16 racks in a daisy-chain or star topology- Max communication distance: 2 km per link (fiber optic); 100 m (Ethernet)- Data transfer rate: 1 Gbps (ensures real-time synchronization of vibration, speed, and temperature data across racks)- Upper-Level Integration Interfaces:- 2 x 10/100/1000 Base-TX Gigabit Ethernet ports (supports TCP/IP, Modbus TCP/IP, OPC UA, Ethernet/IP, Profinet)- 1 x RS-485 serial port (for legacy Modbus RTU communication)- 1 x fiber optic SFP port (for long-distance, EMI-immune transmission to control centers)- Local Interface: 1 x USB 3.0 Type-A port (for on-site configuration, data export, and firmware updates)
Data Processing & Storage	- Data Aggregation Capacity: Collects real-time data from up to 240 functional modules (16 racks × 15 slots)- Local Storage: 8 GB industrial-grade flash memory (stores up to 1 year of historical trend data, 10,000 transient waveform files, and 5,000 alarm events)- Processing Latency: <50 ms (from data acquisition to transmission to upper systems, critical for real-time protection)- Data Compression: Lossless LZ4 compression (reduces storage/transmission bandwidth by up to 60% without data degradation)
System Control & Alarm Management	- Cross-Rack Alarm Logic: Supports programmable inter-rack alarm conditions (e.g., "Turbine A vibration > 100 µm AND Compressor B temperature > 90°C" triggers a system-wide shutdown)- Relay Outputs: 8 Form C (SPDT) programmable relays; max switching voltage 250V AC/30V DC, max current 5A (for global control actions like emergency shutdown, cooling system activation)- Fault Diagnostics: Centralized monitoring of all rack/module health (e.g., power supply faults, sensor open circuits); generates system-level fault codes for quick troubleshooting
