The Bently Nevada 3500/53-03-00 is a highly reliable Electronic Overspeed Detection System designed for the 3500 Series Machinery Protection System. This module provides critical overspeed protection for rotating machinery such as steam and gas turbines, compressors, generators, and turbo-expanders by continuously monitoring rotational speed and initiating a trip signal when preset limits are exceeded.
The -03-00 configuration indicates a Three-Channel System with no additional agency approvals. This triple-redundant architecture enables voting logic configurations (2-out-of-2 or 2-out-of-3) to prevent false trips while ensuring genuine overspeed events are reliably detected.

Triple-Redundant Channel Architecture: Three independent channels provide fault tolerance, enabling voting logic (2oo2 or 2oo3 recommended) that eliminates single points of failure and minimizes nuisance trips while maintaining fail-safe integrity
Versatile Transducer Compatibility: Accepts inputs from both eddy-current proximity probes (Bently Nevada 3300, 7200 series, 3300 RAM) and magnetic pickups, providing flexible installation options for diverse speed sensing applications
High-Speed Overspeed Protection: Designed to meet API Standard 670 and 612 requirements, delivering rapid trip response for critical machinery protection
Wide Speed Measurement Range: Supports up to 99,999 rpm maximum full-scale range with input frequencies up to 20 kHz, accommodating high-speed rotating equipment
Programmable Alarm Setpoints: All Under and Over Alert levels, plus Danger (Overspeed) setpoints, are software-configurable using 3500 Rack Configuration Software
Buffered Transducer Outputs: Front-panel coaxial connectors provide buffered signal outputs for diagnostic and test purposes, with short-circuit and ESD protection
Recorder Outputs: +4 to +20 mA proportional outputs per channel for integration with DCS, PLC, or chart recorders; module operation unaffected by recorder output short circuits
Comprehensive Diagnostics: Front-panel LED indicators and software-accessible diagnostic functions including alarm bypass, peak hold reset, and test mode enable efficient troubleshooting
