Honeywell 51195156-300 TDC 3000 Bernoulli Drive

Product Name and Core Positioning

Core Functions and Technical Features

1. Data Storage and Redundancy
• Optional dual-drive setup for mirrored data storage, providing fault tolerance in mission-critical environments like petrochemical plants
• Employs removable cartridge-based storage (e.g., 20 MB or 44 MB cartridges) for non-volatile data logging of process parameters, alarm histories, and control logic backups.
• Supports hot-swappable cartridge replacement without system downtime, ensuring continuous operation.
• Bernoulli Drive Technology:
• Redundant Configuration:
2. System Integration
• Works with TDC 3000 software suites (e.g., 组态工具包) for parameter configuration and firmware updates.
• DB-25 connector: Links to TDC 3000 controllers (e.g., HPM, PM) or operator stations (GUS) via the LCN (Local Control Network).
• Power Input: Requires +5 VDC (2 A max) and +12 VDC (2 A max) from the TDC 3000 chassis 背板
• Physical Interfaces:
• Compatibility:
3. Reliability and Environmental Resilience
• LED indicators for power status, data transfer activity, and drive health.
• Built-in self-test (BIST) to detect cartridge errors or interface failures
• Operating temperature: 0°C ~ +40°C (non-condensing), storage temperature: -20°C ~ +60°C.
• Resistant to electromagnetic interference (EMI) per EN 61000-6-2/3 and mechanical vibrations (5-500 Hz, 2g)
• Industrial-Grade Design:
• Diagnostic Capabilities:

Technical Specifications Table

Key Design Features

1. Legacy System Compatibility
• Designed for retrofitting older TDC 3000 installations, replacing obsolete floppy disk drives with higher-capacity, more reliable Bernoulli storage
• Supports backward compatibility with TDC 2000 systems via adapter modules
2. Ease of Maintenance
• Cartridge replacement requires no tools, reducing mean time to repair (MTTR) to <5 minutes.
• Honeywell provides 10 years of 备件支持 and third-party refurbishment options (e.g., DCS Center) for long-term operational continuity
3. Security and Data Integrity
• Cartridges are write-protectable to prevent accidental data overwriting.
• Data encryption (optional via TDC 3000 software) safeguards sensitive process information
