Bently Nevada 3500/94 (350094-03-00-00) – VGA Display Module for 3500 Machinery Protection Racks

The Bently Nevada 3500/94 VGA Display Module, part number 350094-03-00-00, is designed to give operators a clear, at-a-glance view of machine condition data from the 3500 rack on a standard VGA monitor. From my experience, it’s the go-to choice when you want rich trending, alarm lists, and channel status without tying up your DCS or a separate PC. You might notice that it typically replaces or complements the 3500/93 System Display in sites that prefer a larger screen or remote panel visibility.

Key Features

• VGA Output for Large-Format Viewing: Connects to a standard VGA monitor for clear visualization of vibration, speed, and process values.
• Native 3500 Rack Integration: Receives data via the 3500 backplane; no separate data server is required.
• Alarm Lists and Status Pages: Quickly review active/latched alarms, events, and channel health in one place.
• Trends and Channel Details: Operators can view trends and channel summaries to support quick troubleshooting.
• No Impact on Protection Functions: Display is independent of the protection logic, which typically runs in the monitoring modules.
• Easy Slot-Based Installation: Fits into a standard 3500 rack slot; uses the existing rack power.

Technical Specifications

Application Fields

You’ll typically see the 3500/94 in rotating equipment protection systems where operators want a clear local HMI without adding a PC. It’s widely used in:

• Oil & Gas (compressors, turbines, pumps)
• Power Generation (steam and gas turbines, balance-of-plant)
• Chemical & Petrochemical plants
• Pulp & Paper, Metals, and other heavy industries

Advantages & Value

• Reliability: Purpose-built for the 3500 ecosystem, which seems to be the standard in many critical machinery protection setups.
• Compatibility: Works natively with 3500 rack data—no middleware or custom drivers to maintain.
• Cost Control: Uses a simple VGA monitor; no need for an industrial PC HMI in many cases.
• Operational Clarity: Operators can see alarms and trends right at the cabinet, which typically speeds up first-line diagnostics.
• Support: Easy to replace and commission alongside existing 3500 modules.

Installation & Maintenance

• Panel/Cabinet: Install in a clean, ventilated 3500 rack cabinet; follow rack grounding and EMC practices.
• Cabling: Use a quality VGA cable of appropriate length; avoid routing parallel to high-voltage conductors.
• Power: No separate power—ensure the rack power supply (3500/15) has adequate capacity.
• Safety: De-energize the rack slot before insertion/removal; observe ESD precautions when handling the module.
• Routine Care: Periodically check connectors, clean dust from the cabinet, and verify the monitor displays alarm pages and trends correctly.
• Firmware/Compatibility: Keep the display module aligned with the rack’s configured revision level; in most cases, matching firmware revisions across 3500 components prevents nuisance issues.

Quality & Certifications

• CE compliant for industrial environments
• UL/cUL listed (typical for 3500-series modules)
• RoHS compliant design
• Manufacturer-grade quality control; covered by our 365-day warranty

Commonly Paired Components (for a complete 3500 solution)

• 3500/22M Transient Data Interface (plant historian and advanced diagnostics)
• 3500/93 System Display (for compact cabinet displays when VGA is not needed)
• 3500/15 Power Supply (AC or DC variants, depending on rack design)
• 3500/40M, 3500/42M Monitoring modules (vibration/position/process)

A maintenance lead told me they swapped to the 3500/94 to put a 19-inch VGA screen on the cabinet door—trend visibility improved, and operators could acknowledge alarms faster during startups. That matches what we typically see when plants want straightforward, reliable visibility without complicating the system architecture.
