Bently Nevada 350005-05-00 (3500/05 System Rack) – Core Chassis for 3500 Machinery Protection Systems

The Bently Nevada 350005-05-00 corresponds to the 3500/05 System Rack, the backbone chassis for the 3500 series machinery protection and condition monitoring platform. From my experience, this is the piece that makes multi-channel vibration, Keyphasor, and relay modules work together reliably—housing the backplane, the power slots, and the front-access module bays. If you’re building or expanding a plant-wide 3500 system, this rack is typically the starting point.

Our Order Process & Guarantees

Key Features

• 14‑slot, 19-inch rack chassis – EIA‑310 compatible frame designed to host 3500 monitoring, relay, power and interface modules.
• Modular backplane architecture – Simplifies system build, expansion, and maintenance; modules are front-insertable and typically hot‑swappable.
• Redundant power support – Accepts dual 3500/15 Power Supply modules for high availability in critical machinery protection.
• Flexible communications – Works with 3500/22M TDI for data interfaces (e.g., Modbus TCP) and connection to plant historians or System 1 software.
• Mixed monitoring capability – Hosts proximity, seismic, Keyphasor, temperature, and relay modules to cover most rotating assets.
• Industrial installation options – Fits standard 19-inch cabinets; panel/bulkhead mounting is commonly used in control rooms and skid panels.
• Serviceability in the field – Clear slot mapping, front access, and well-documented wiring via I/O modules makes daily work faster.

Technical Specifications

Application Fields

Plants typically standardize on the 3500/05 rack when they need continuous protection and API 670‑style monitoring on:

• Steam and gas turbines in power generation
• Compressors and expanders in oil & gas and petrochemical units
• Large process pumps and fans in refining and chemical plants
• Critical rotating assets on pipeline stations and LNG facilities
• Pulp & paper and steel mills where high uptime is non-negotiable

Advantages & Value

• Reliability first – The rack supports redundant power and proven monitor modules. You get stable protection even during maintenance or module replacement.
• Compatibility across the board – Works with Bently Nevada 3500 monitors, TDI, relays, and I/O, making spares and expansion straightforward.
• Lifecycle savings – Standardized chassis simplifies inventory, training, and troubleshooting—usually cuts downtime and service calls.
• Scalable architecture – Start with essential monitoring and add channels or communications as the asset base grows.
• Support ready – Documentation and global service ecosystem are strong, which seems to be a big plus on multi-site projects.

Installation & Maintenance

• Cabinet and environment – Mount in a clean, ventilated 19-inch cabinet or protected panel enclosure. Allow space for cable bend radius at the rear I/O.
• Power and grounding – Use 3500/15 Power Supply modules; follow GE/Bently grounding and shielding practices to minimize noise pickup.
• Wiring – Land transducer and relay wiring on the appropriate I/O modules. Keep sensor and power wiring segregated when possible.
• Safety – De‑energize power before inserting/removing modules unless procedures specify hot-swap is acceptable for that module type.
• Routine care – Periodically check terminal tightness, clean dust from ventilation paths, and keep firmware of interface modules (e.g., TDI) up to date as recommended.

A maintenance lead at a gas pipeline station told us they keep a spare 3500/05 rack in the shop—when they need to reconfigure a train, they build it offline and swap it over a planned stop. It typically saves them hours.

Commonly Paired 3500 Modules (for planning)

• 3500/15 Power Supply – AC or DC versions; supports redundant operation in the 3500/05 rack.
• 3500/22M TDI – Transient Data Interface; provides system communications and historian links (e.g., Modbus TCP, System 1 connectivity).
• 3500/25 Keyphasor – Speed and phase reference for rotating machinery analysis.
• 3500/40M, 3500/42M Monitors – Proximitor/seismic channels for vibration, axial position, and radial measurements.
• 3500/32M Relay – Alarm and trip relays for protective logic, often used with redundancy strategies.

Quality & Certifications

• CE and UL/cUL markings on applicable modules and assemblies
• RoHS compliance for electronic assemblies where specified
• Manufactured under ISO 9001 quality systems (manufacturer)
• Warranty from us: 365 days
