Bently Nevada 3300-53-02-02-00-60-05-00-00-00 Overspeed Detection System Module Rack Based

Bently Nevada 3300-53-02-02-00-60-05-00-00-00 Overspeed Detection System Module

Product Overview
The Bently Nevada 3300/53 Overspeed Detection System is a rack-based protection module engineered to prevent catastrophic failure of steam, gas, and hydro turbines caused by uncontrolled acceleration. Using triple-redundant speed inputs and two-out-of-three (2oo3) voting logic, the 3300/53 meets API 670 and IEC 61508 SIL 2/3 requirements with response times as fast as 40 ms. Whether you are modernizing an aging mechanical governor or adding an independent electronic overspeed trip, the 3300/53 integrates seamlessly with existing 3500 racks, System 1 software, and plant historians.

Key Features & Benefits
• Triple-channel speed monitoring—accepts eddy-current probes, magnetic pickups, or optical encoders
• 2oo3 voting plus configurable 1oo2, 2oo2, or 1oo1 logic for diverse safety strategies
• Programmable setpoints from 1 rpm to 32 kHz with 0.01 % accuracy
• < 40 ms relay trip time for API 670 compliance
• Hot-swappable module and terminal strips—no rack shutdown required
• SIL 2 certified (SIL 3 capable with external voting) for IEC 61511 safety loops
• Front-panel LEDs for Power, OK, Alert, Danger, and individual channel status
• Dual relay outputs (SPDT) plus solid-state driver for external trip solenoids

Typical Applications
• Steam turbine overspeed protection retrofits
• Gas compressor train safety shutdown systems
• Hydro turbine runaway prevention
• API 612 & 617 test-stand overspeed validation
