Description

The Bently Nevada 133396-01 is a specialized I/O module designed for the 3500/53 Electronic Overspeed Detection System. This module serves as a critical component in machinery protection, providing a highly reliable and fast-response redundant tachometer system. It is engineered to meet the stringent requirements of American Petroleum Institute (API) Standards 670 and 612 for overspeed protection in critical rotating machinery.

Features

Designed for integration with the 3500 Series Machinery Detection System.
Supports redundant configurations, including 2-out-of-2 or 2-out-of-3 (recommended) voting logic.
High-speed response time of less than 50 ms for critical safety shutdown applications.
Internal termination design using 10-pin Euro-style connectors for direct wiring.
Epoxy-sealed construction for enhanced environmental durability.

Applications

Power Generation: Monitoring and protection for steam, gas, and hydro turbines and generators.
Oil & Gas: Overspeed protection for large centrifugal and reciprocating compressors and high-capacity pumps.
Industrial Processing: Safety monitoring for large fans, rolling mills, and high-speed drying cylinders in paper machines.
LNG Liquefaction: Protection for massive refrigeration compressors.

Installation Guidelines

Slot Placement: This is a rear I/O module; it must be installed in the 3500 rack directly behind the corresponding 3500/53 monitor module.
Wiring: Connect speed sensors (Proximitor or Magnetic Pickups) to the appropriate channel inputs. For 2-out-of-3 (2oo3) voting, ensure all three sensors are correctly wired to the respective channels.
Handling: Ensure the rack power is disconnected before installing or removing the module to prevent electrical damage. Use standard ESD protection practices when handling the module.
Termination: This model utilizes internal terminations; ensure wires are securely landed on the 10-pin Euro-style connectors.

FAQs

What is the primary function of the 133396-01?
It acts as an I/O interface for the 3500/53 Electronic Overspeed Detection System, providing signal conditioning and independent channel monitoring for proximity probes.

Can this module be used in a 2-out-of-3 voting system?
Yes, the 3500/53 system is designed to support 2-out-of-2 or 2-out-of-3 voting configurations to ensure high reliability and fault tolerance.

Is this module compatible with all 3500 racks?
The Overspeed Detection System requires a 3500 rack equipped with redundant power supplies to function correctly.
