General

  • Manufacturer GE / Bently Nevada
  • Model 3500/54M 286566-01
  • Condition New Original ready stock
  • Product Family 3500/54M-04-00 286566-05,3500/54M,3500/53 133388-01
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Backplane Data Transmission: Real-time communication with the 3500/22M (RIM) module via the 3500 rack backplane, uploading speed data, alarm status, and event lists to the host computer.
  • Software Configuration Interface: Parameter settings (such as trip point, hysteresis, tooth count, etc.) are performed using the 3500 Rack Configuration Software, supporting remote access via Ethernet or serial interface.
  • Status Indicators (LEDs): The module panel features OK, TX/RX (communication in progress), and Bypass indicators, providing intuitive feedback on on-site physical communication and operating status.
  • External System Integration: Supports sending data to DCS or PLC systems for secondary monitoring via the 3500/92 communication gateway using Modbus RTU/TCP or Ethernet/IP protocols.
  • Steam/Gas Turbines: Monitor spindle speed to prevent overspeeding due to sudden load drops.
  • Large Compressors: Ensure impellers operate within safe speed ranges during multi-stage compression processes.
  • Expanders: Monitor speed during cryogenic processes to prevent overspeed damage to seals.
  • Generators: Monitor generator frequency-dependent speed stability to ensure grid synchronization safety.
  • Reverse Flow Monitoring: In pump applications, prevent backflow of media that could cause reverse rotation during shutdown, damaging bearings or mechanical seals.
  • Ultra-fast Response: The system has an extremely short response time (typically < 50 milliseconds), ensuring forced shutdown of the oil circuit before high-speed equipment such as steam turbines experience overspeed.
  • Voting Logic: Supports 2-out-of-2 (2oo2) or 2-out-of-3 (2oo3) logic configurations. In 2oo3 mode, a single sensor failure will not cause false tripping, greatly improving system availability.
  • Self-Diagnostic Function: The module continuously monitors the sensor circuit (open circuit, short circuit) and the status of internal electronic components. Once a hardware anomaly is detected, a failure warning will be immediately issued via the OK relay.
  • API Standard Compliance: Fully compliant with the mandatory requirements of API 670 (Mechanical Protection Systems Standard) and API 612 (Special Purpose Steam Turbine Standard) regarding electronic overspeed protection.
