BENTLY 133396-01

Description

Product Description

The BENTLY 133396-01 is a critical power supply module designed for the Bently Nevada 3500/42M Proximitor® Seismic Monitoring System and related 3500 series racks. This module provides clean, regulated, and isolated DC power to the vibration, position, and seismic monitoring modules within the rack, such as the 3500/42M Proximitor® Seismic Monitor. The reliable operation of the entire machinery protection system depends on the stable output of the BENTLY 133396-01. Engineered for the critical environment of rotating machinery protection, this power supply ensures that sensitive monitoring electronics receive uninterrupted and noise-free power, which is essential for accurate measurement and reliable alarm generation. For engineers maintaining turbine and compressor protection systems, the BENTLY 133396-01 is a key component for system integrity.

Product Parameters

• Product Type: Power Supply Module (for 3500 Series Racks)
• System Series: Bently Nevada 3500 Machinery Protection System, specifically for racks housing 3500/42M and related modules.
• Input Voltage: Typically accepts a wide-range AC input (e.g., 90-132 VAC / 180-264 VAC, 47-63 Hz) or often a DC input option (e.g., 88-250 VDC).
• Output Voltages: Provides multiple isolated DC output rails required by the monitoring modules, commonly:
  • +5 VDC for digital logic circuits.
  • ±15 VDC for analog circuitry and sensor excitation.
  • +24 VDC for relay drivers and external interfaces.
• Output Power: Rated for a specific wattage (e.g., 60W) to support a full rack of monitoring modules.
• Redundancy Support: Can be configured in a parallel, load-sharing redundant pair (N+1) to ensure continuous power in the event of a single supply failure.
• Communication & Diagnostics: Integrates with the 3500 rack’s communication path, providing status and health information (Power OK, Failure) to the system’s monitoring software.
• Form Factor: Designed to mount in the dedicated power supply slots of a 3500 series rack.
• Status Indicators: LED indicators for AC Power On, DC Output OK, and Fault conditions.

Advantages and Features

• Critical for System Reliability: The BENTLY 133396-01 is the foundation of the rack’s operation; without stable power, the entire monitoring and protection chain is disabled.
• Clean and Stable Power: Provides excellent voltage regulation and low noise, which is paramount for the accuracy of sensitive vibration, position, and seismic measurements.
• High Availability with Redundancy: The built-in support for parallel redundant operation is a standard best practice in critical machinery protection, ensuring no single point of failure in the power path.
• Integrated Diagnostics: Its status is communicated to the system, allowing for remote monitoring and early warning of potential power supply issues before they affect protection functions.
• Hot-Swappable Design: In a redundant configuration, a faulty BENTLY 133396-01 module can be replaced online without shutting down the monitoring system or the protected machinery.
• Rugged Industrial Design: Built to withstand the temperature and vibration environment found in power generation and industrial plants.

Application Cases in Key Fields

• Power Generation (Gas & Steam Turbines): Powering vibration and seismic monitoring racks that protect turbine-generator sets from mechanical damage.
• Oil & Gas (Compressor Stations): Providing reliable power to monitoring systems on critical centrifugal and reciprocating compressors in pipelines and processing plants.
• Petrochemicals: Used in protection systems for large rotating equipment like cracked gas compressors and turbine-driven pumps.
• Marine Propulsion: Powering monitoring racks for main propulsion turbines and reduction gears on ships.
• Heavy Industry: Supporting protection systems on large fans, mills, and pumps in mining and metals processing.

Comparisons with Competing Products

The BENTLY 133396-01 is specific to the Bently Nevada 3500 ecosystem. Its competitors are power supplies from other machinery protection system vendors:

• Vs. Emerson/CSI Power Supply Modules: For systems like the CSI 6500, the power supply design is different and not interchangeable. The BENTLY 133396-01 is optimized for the 3500 rack’s mechanical and electrical interface.
• Vs. General Industrial Power Supplies: A generic 24V supply cannot provide the multiple voltage rails (+5V, ±15V), the communication integration, the hot-swap capability, or the certification for use in a safety-related monitoring system.
• Vs. Older Bently Nevada Power Supplies (e.g., for 3300 systems): The BENTLY 133396-01 is designed for the newer 3500 platform, offering better diagnostics and compatibility with modern monitoring modules.
• Vs. Internal PLC Power Supplies: PLC power supplies are for logic control, not for precision analog measurement systems. They lack the specific voltage combinations and noise immunity required by vibration monitoring systems.

Selection Suggestions and Precautions

• Selection Advice:
  1. Verify Rack Compatibility: Confirm that your 3500 series rack model is designed to use the BENTLY 133396-01 power supply. Check the rack’s configuration and manual.
  2. Calculate Total Rack Load: Ensure the combined power consumption of all monitoring modules, communication modules, and relays in the rack does not exceed the rated output of the power supply, even in a redundant pair sharing the load.
  3. Plan for Redundancy: For any critical machinery protection application, always specify and install a redundant pair of BENTLY 133396-01 power supplies from the outset.
  4. Source from Authorized Channels: Purchase from Emerson/Bently Nevada or authorized distributors to ensure authenticity, correct firmware, and full compatibility.
• Important Precautions:
  1. High Voltage Hazard: The module connects to AC mains voltage. Installation must be performed by qualified personnel following strict lock-out/tag-out (LOTO) procedures for the associated equipment.
  2. Observe Redundancy Wiring: When installing a redundant pair, follow the wiring diagram precisely to ensure proper load sharing and isolation. Incorrect wiring can defeat the redundancy.
  3. Do Not Mix Models in Redundant Pair: In a redundant configuration, both power supplies must be identical models (same part number and revision) to ensure proper operation.
  4. Firmware/Software Compatibility: In newer systems, verify that the power supply’s firmware (if any) is compatible with the other modules in the rack and the system software (System 1™).
  5. Post-Replacement Verification: After installing a new BENTLY 133396-01, verify all output voltages with a multimeter and confirm that the module shows a healthy status in the monitoring software before considering the system operational.
