Bently Nevada 350093-03-00-00 (3500/93 System Display) – Local Rack Display for the 3500 Machinery Protection System

The Bently Nevada 350093-03-00-00—commonly referenced as the 3500/93 System Display—is the front-panel display for the 3500 rack. It lets operators quickly view vibration, speed, temperature, and system status without a PC. From my experience, plants like it because it’s simple, deterministic, and doesn’t interfere with protection logic. You might notice that it pulls live values, alarms, and events directly from the rack backplane, so there’s no extra wiring or external power to think about.

Our Order Process and Guarantees

• Warranty period: 365 days
• Delivery: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• Dedicated rack-front display – Reads live data and alarm states directly from the 3500 backplane for quick checks at the cabinet.
• No external power – Typically powered by the rack, which keeps wiring clean and reduces panel complexity.
• Operator-friendly navigation – Front-panel keys/menu structure make it easy to find channels, setpoints, and events.
• Non-intrusive to protection – Display does not alter protection functions; it’s purely visualization, which many safety teams prefer.
• Fast replacement – Drop-in fit for 3500 racks. Field teams typically swap and validate within a short maintenance window.
• Built for harsh duties – Suited for continuous industrial operation when properly installed in a protected cabinet environment.

Technical Specifications

Application Fields

Typically used anywhere a 3500 rack is installed. That includes steam and gas turbines, centrifugal compressors, large pumps, fans/blowers, and critical gearboxes—common across oil & gas, petrochemical plants, power generation, steel, paper, mining, and pipelines. One thing I appreciate is how maintenance crews can walk up to the rack, scroll through channels, and confirm alarm setpoints before a start-up without launching software.

Advantages & Value

• Reliability – Display function is segregated from protection logic, which seems to be the safer approach for critical machinery.
• Compatibility – Designed for the 3500 rack family; no extra gateways just to see values locally.
• Cost control – Saves engineering hours during commissioning and troubleshooting; fewer accessories to maintain.
• Supportability – Widely used, well-documented, and easy for operators to adopt with minimal training.

Installation & Maintenance

• Cabinet standards – Install in a properly grounded 3500 rack within an enclosed cabinet to protect from dust, vibration, and moisture.
• Ventilation – Maintain adequate airflow around the rack. Avoid direct sunlight on the display window where possible.
• Wiring – No field wiring to the display; it interfaces via the rack backplane. Keep backplane and power supply connections secure and clean.
• Safety & ESD – Use proper ESD protection. Power-down and follow site LOTO policies if you remove or replace the module.
• Routine care – Periodically clean the front panel with a soft lint-free cloth. Check firmware alignment with the rest of the rack during planned outages.
• Documentation – Keep a list of critical channels and alarm setpoints handy; it speeds up navigation and reduces mistakes during a trip investigation.

Quality & Certifications

• CE compliant; typically UL/cUL recognized
• RoHS conformity in many cases
• Manufactured under ISO 9001 quality systems (typical for this product line)
• Warranty: 365 days from us

A maintenance supervisor recently mentioned their -03 variant dropped into the rack and matched existing firmware levels without any rework—exactly the kind of low-risk swap teams like before a turnaround.
