Bently Nevada 3300/03-02-00 System Monitor 220VAC Redundant Power Supply Version

Product Overview
The Bently Nevada 3300/03-02-00 is the standard model in the GE Bently Nevada 3300 series rack-mount system monitor. Mounted in a 19-inch rack, it features integrated power, communication, and display interfaces. It can simultaneously manage up to 16 monitoring modules (e.g., vibration, temperature, speed, displacement), providing 24/7 continuous protection and diagnostics for critical equipment such as steam turbines, gas turbines, large-capacity compressors, and generators. The suffix "-02-00" designates a 220 V AC redundant power supply, no special coatings, and no additional certifications. It is compatible worldwide and offers strong field interchangeability.

Core Functions
• Comprehensive Monitoring: Supports the full range of 3500/3300 monitoring cards, allowing for a mix of vibration, temperature, speed, and relay modules within a single chassis.
• Dual redundant power supplies: 220 V AC/DC auto-sensing, hot-swappable, power failure switchover in <5 ms, MTBF >250,000 h
• High-speed Communications: Front RS-232/485 and rear Ethernet ports support Modbus RTU/TCP and OPC UA, enabling seamless integration into DCS/SCADA systems.
• Real-time Display: 6-line LCD (128×64) displays channel status, alarm values, bar graphs, and trend charts in a cyclic manner, with 6-key front panel for quick navigation.
• Event Log: 2 MB non-volatile memory stores up to 1,000 alarm/fault/operation logs with 1 ms timestamp accuracy.
• Self-Diagnostics: Continuously monitors power supply, fuse, fan, and backplane temperatures, instantly sending fault information to System 1 software.
• Online Configuration: Configurable via Bently Nevada System 1 or Rack Configuration Software for remote/offline configuration of channel parameters, alarm logic, and relay mapping.
• Standard 6U rack: 483 mm × 267 mm × 44 mm (1E), supports mixed 3U/6U installation, saving control cabinet space.
