Description

The 3500/54 (Part Number: 133396-01) is an Overspeed Detection Input/Output (I/O) Module manufactured by Bently Nevada (Baker Hughes) as part of their flagship 3500 Series Machinery Protection System.

Key Technical Specifications & Features

• Primary Function: Designed to interface speed-measuring sensors (such as proximity probes or magnetic pickups) with the 3500 system to continuously monitor rotational speed and provide critical overspeed protection and trip commands.

• System Compatibility: Works in conjunction with the 3500/54 (or 3500/53) front-end monitoring modules within a standard 3500 rack environment.

• Inputs: Accepts speed pulse input signals from eddy current proximity sensors or magnetic pickups.

• Speed Range & Accuracy: Capable of measuring high-speed rotations up to 50,000 RPM (depending on configuration/events per revolution) with high precision (typically $\pm0.1\%$ of reading).

• Response Time: Ultra-fast response time of $< 10\text{ ms}$ to ensure safety interlocks trip immediately during catastrophic overspeed events.

• Outputs:

  • Provides safety-rated relay alarm/trip outputs.

  • Generates 4–20 mA full-scale analog outputs for integration with process control systems (DCS/PLC).

• Certifications & Compliance: Built to meet API 670 standards, SIL 2 safety compliance, and hazardous area certifications (such as ATEX/IECEx Zone 2).

Typical Applications

• Steam, gas, and hydro turbines

• Large industrial compressors and pumps

• Critical rotating machinery requiring reliable, fail-safe overspeed shutdown protection to prevent catastrophic equipment failure.
