Bently Nevada 3500/92 – 350092-04-01-00 Communication Gateway for 3500 Rack Data Integration

The Bently Nevada 3500/92 (ordering code 350092-04-01-00) is a communication gateway module for the 3500 machinery protection system. From my experience, this is the go-to card when you need a stable Ethernet pathway to bring vibration and system health data from the rack into a DCS, PLC, or historian. It typically sits in a single slot of the 3500 rack and exposes configured measurements over Ethernet, so your controls or condition monitoring software can read them without touching every monitor card one by one.

Our Order Placement Process and Guarantees

Key Features

• Ethernet data gateway – Provides a clean interface for 3500 rack data to plant networks, typically used for Modbus/TCP or similar industrial protocols depending on build options.
• Single-slot 3500 form factor – Installs neatly in standard 7- or 14-slot 3500 racks without external power wiring.
• Rack-wide data access – Publishes key process and vibration parameters configured in the rack, which simplifies DCS/PLC mapping.
• Designed for reliability – Industrial temperature, robust backplane power, and proven uptime in rotating equipment environments.
• Fast commissioning – In many cases, you map tags once and reuse templates across similar assets to cut configuration time.
• Compatibility-first approach – Typically used alongside 3500/22M TDI and standard monitor cards, so it fits easily into existing architectures.

Technical Specifications

Application Fields

You’ll usually find the 3500/92 in plants where rotating assets matter: steam and gas turbines, compressors, big motors, pumps, and gearboxes. Typical sectors include oil & gas, petrochemical, power generation, pulp & paper, mining, and water utilities. One thing I appreciate is how easily it drops into existing DCS/PLC environments, letting maintenance teams visualize vibration and alarm status without changing their control strategy.

• Real-time vibration and status to DCS/PLC for interlocks and annunciation
• Data handoff to historians/CMMS for trending and reliability analytics
• Bridge to condition monitoring software without disturbing protection logic

Advantages & Value

• Reliability – Purpose-built for the 3500 platform, so it’s as stable as the protection system you rely on.
• Compatibility – Most plants map it through Modbus/TCP or similar, reducing integration friction with major DCS/PLC brands.
• Lifecycle savings – Centralized data access means less time wiring, fewer gateways, and simpler long-term support.
• Supportability – Firmware and configuration are straightforward; technicians can replicate tag maps across similar machines.

A maintenance supervisor put it simply: “We swapped in a 3500/92, restored the saved map, and the DCS saw everything within minutes.” That tends to be the experience when the network and rack firmware are aligned.

Installation & Maintenance

• Panel/Cabinet – Mount the 3500 rack in a clean, ventilated cabinet. Keep ambient within spec and avoid direct vibration/heat sources.
• Wiring & Grounding – Use industrial-grade Ethernet cabling; maintain proper shielding and single-point grounding practices.
• Network – Assign static IPs, segregate control networks as needed, and confirm protocol configuration (register maps, byte order, scaling).
• Commissioning – Verify rack firmware levels and TDI communication; export and archive configuration files for disaster recovery.
• Maintenance – Periodic visual inspection, dust cleaning, and configuration backups. Plan firmware updates during scheduled outages after validating release notes.
• Safety – De-energize the rack when practical during module insert/removal, and follow site lockout/tagout rules.

Quality & Certifications

• Certifications – CE and UL/cUL are commonly available for 3500-series modules; RoHS conformity is typical for current builds.
• Manufacturing – Produced under ISO 9001 quality systems (typical for Bently Nevada product lines).
• Warranty – 365-day warranty provided by us for this item.

Notes: The 350092-04-01-00 variant appears to be an Ethernet gateway build that, in many cases, is set up for Modbus/TCP mapping. If you need us to confirm the exact protocol set and firmware for your rack revision, share your current 3500 configuration and we’ll align the order accordingly.
