Features:
- Real-Time Speed Monitoring – Continuously tracks machinery speed to prevent overspeed or reverse rotation damage.
- Wide Measurement Range – Supports 0 to 99,999 RPM with maximum input frequency of 20 kHz.
- Standards Compliant and Robust – Meets API 670, CE, and IEC 61000 standards with industrial-grade operating temperature tolerance.
The Bently Nevada 3500/54M 286566-01 Overspeed Detection Module provides critical protection for high-speed rotating machinery. By monitoring real-time speed and triggering immediate trips, it prevents catastrophic equipment failures, ensuring operational safety and reliability. The module’s wide measurement range and fast input frequency handling make it suitable for demanding industrial applications.
Powered from the 3500 series rack backplane at 24 VDC, the 3500/54M 286566-01 integrates seamlessly into existing 3500 machinery protection systems. Its operating temperature tolerance of -40°C to +85°C ensures performance in harsh environments, while compliance with API 670, CE, and IEC 61000 guarantees global standards adherence.
Operators using the 3500/54M 286566-01 benefit from accurate monitoring, early warning, and rapid response capabilities. The module’s design enhances predictive maintenance strategies, reduces unplanned downtime, and provides reliable protection for turbines, compressors, motors, and other critical rotating machinery in industrial plants.
The 3500/54M 286566-01 Bently Nevada Overspeed Detection Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

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.
