BENTLY NEVADA 3500/94 (120M8155-01) – VGA Display Module for 3500 Machinery Protection Racks

The BENTLY NEVADA 3500/94 (P/N 120M8155-01) is the VGA display module designed for the 3500 series machinery protection system. From my experience, this module is typically chosen when teams want a clear, plant-floor view of rack status, trends, and alarms on a standard external monitor—without adding a separate industrial PC. You might notice that it fits directly in the 3500 rack and pulls data from the system over the rack network, so operators can quickly verify machine condition at a glance.

Company’s Order Placement Process and Guarantees

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

Key Features

• VGA output to external monitor – Presents 3500 rack status, alarms, bars, trends on a standard display for convenient local viewing.
• Rack-integrated design – Installs in the 3500 rack, leveraging the backplane for power and data; no separate PC typically required.
• Networked data access – Communicates with the 3500 system over Ethernet, enabling display of one rack or, in many cases, multiple racks.
• Operator-friendly navigation – Simple on-screen menus for quick drill-down to point status, which maintenance teams tend to appreciate under time pressure.
• Designed for industrial environments – Built to match the 3500 platform’s reliability expectations in harsh conditions.

Technical Specifications

Application Fields

You’ll usually see the 3500/94 used wherever a 3500 rack is protecting rotating assets and the team wants a simple local display. That includes:

• Oil & gas turbomachinery skids (compressors, turbines, pumps)
• Power generation (steam/gas turbines, balance-of-plant machinery)
• Petrochemical and refinery units with centralized 3500 cabinets
• Pulp & paper and mining facilities monitoring critical fans and mills

One maintenance lead told us the simple VGA screen near the rack saved them time during a trip event—they could confirm channel status right at the cabinet before escalating.

Advantages & Value

• Lower integration effort – Uses a standard VGA monitor and the rack’s own network, which typically reduces engineering hours versus a separate HMI.
• Operational clarity – Clear on-screen alarms and trends support faster troubleshooting during abnormal conditions.
• Lifecycle alignment – Matches the 3500 platform for spares, training, and long-term support, simplifying MRO planning.
• Compatibility you can count on – Designed for 3500 racks and works with common configurations using 3500/22M TDI.
• Cost control – Avoids the need for an additional industrial PC for basic local visualization in many cases.

Installation & Maintenance

• Cabinet standards – Mount in a standard 19″ 3500 rack within a well‑ventilated, low‑dust cabinet; maintain ambient temperature within spec.
• Wiring & grounding – Connect VGA cable to the external monitor; use shielded network cables; bond cabinet ground to plant earth.
• Safety precautions – Power down or place the rack in a safe state before module insertion/removal; observe ESD handling.
• Routine care – Periodically inspect connectors, clean dust from the cabinet, and check for loose cables; apply firmware updates when recommended by the manufacturer.
• Spare strategy – Keeping one spare module on site seems to be a practical approach for critical units.

Quality & Certifications

The 3500 platform is widely recognized for industrial reliability. The 3500/94 module is typically supplied with CE and UL/cUL conformity and aligns with RoHS requirements. Manufacturer’s standard warranty is commonly 12 months; our provided coverage is 365 days, and we support verification of conformity documents upon request.
