Features:
- High Reliability Design For Critical Overspeed Protection
- Integrated Terminations For Simplified Sensor Connections
- Supports Multiple Voting Configurations To Enhance System Availability
The Bently Nevada 133396-01 is an I/O module built for the 3500/53 overspeed detection system. It acts as a key component in mechanical protection, triggering safety shutdowns when monitored machinery exceeds preset speed limits.
This module features built-in terminal blocks, allowing direct connection of proximity probes or magnetic tachometers. The internal terminations streamline installation and reduce the complexity of panel wiring.
The 133396-01 also supports multiple voting logic options, which help maintain reliable operation even if a single channel experiences a fault. Its design meets API 670 standards, making it suitable for critical equipment such as turbines and large compressors, while providing real-time speed monitoring to control systems.
The 133396-01 Bently Nevada Overspeed Detection I/O Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Sensor Interface: Each module can connect to a single pulse signal from an eddy current sensor (such as the 3300 8mm series) or a magnetoelectric sensor.
- Backplane Communication: Communicates with the front-end 3500/53 main module via the 3500 frame backplane and exchanges data with other modules within the system (such as the 3500/22M transient data interface module).
- Remote Interface: Provides back-end panel connection, supporting remote activation of System Reset, Trip Multiply, and Rack Alarm Inhibit functions.
- External Gateway: Can be used with the 3500/92 communication gateway module to integrate speed and status data into the factory DCS or PLC system via standard protocols.
- Core Power Equipment: Overspeed shutdown protection for steam turbines and gas turbines to prevent catastrophic damage caused by overspeed.
- Heavy-duty industrial compressors: Real-time speed monitoring and safety interlocking for critical compressor units in oil and chemical production.
- Large pump sets: Mechanical protection for critical power pumps in oil refineries or water conservancy projects.
- Compliance protection: Suitable for overspeed protection systems that must meet API 670 or API 612 industry standards.
- Voting logic control: Supports 2-to-2 or 3-to-2 redundant voting logic (requires multiple modules), comparing readings from multiple sensors to determine whether to trigger a shutdown, balancing safety and availability.
- Fast relay triggering: When overspeed or sensor failure (NOT OK) is detected, an alarm or interlock trip signal is output through an integrated fast-response relay (e.g., with 3500/32 or 3500/34 modules).
- Real-time status feedback: LED indicators: The panel features an OK light (module status), a TX/XR light (communication status), and a Bypass light (bypass mode). Analog recording: Provides a 4-20 mA recorder output, proportionally feeding back speed information to the recording instrument or monitoring system.
- Buffered output: A coaxial connector on the front panel allows for buffered sensor signal output for on-site diagnostics using portable analyzers.
