Product Brief: Bently Nevada 3500/94 VGA Display (147663-01)
The 3500/94 VGA Display (part number 147663-01) is a dedicated operator interface module for the Bently Nevada 3500 series machinery protection system. It provides a local, real-time graphical display of machinery health data directly from the 3500 rack, including vibration values, temperature readings, speed, axial position, alarm statuses, and event lists. The module connects to the 3500 rack via the TDXnet or TDIX communication processor and displays data without requiring a separate computer or DCS workstation.
This display is typically mounted in an instrument panel door or control room console near the 3500 rack, allowing operators and maintenance personnel to view critical machine conditions at a glance.
Key Features
High-resolution VGA (640 x 480) color TFT LCD – clear, easy-to-read graphics.
Direct connection to 3500 rack communication processor (3500/20, 3500/22, TDXnet, TDIX).
Real-time display of monitored parameters (vibration, temperature, speed, position, etc.).
Alarm and event indication – visual alert for Alert/Danger conditions.
Trend viewing – historical data and time plots.
Bar graph, digital, and strip chart formats – user-selectable display modes.
Touchscreen option (if equipped – base 147663-01 is typically display only; touch version has different suffix).
Panel or console mounting – standard 1/2 VGA panel cutout.

Application Scenarios (use cases)
| Application Area | Description |
|---|---|
| Steam Turbine Control Room Panel | Mounted on generator control panel, displays bearing vibration, thrust position, and case expansion locally for operators. |
| Gas Turbine Compressor Station | Installed in local control console at compressor skid – shows real-time radial vibration and exhaust temperature spread. |
| Hydro Turbine Plant Operator Desk | Provides continuous display of thrust bearing temperature, wicket gate position, and shaft runout. |
| Offshore Platform Machinery Room | Local display for critical compressor train – allows quick alarm checks without accessing DCS screens. |
| Refinery Compressor House | Mounted near 3500 rack for maintenance walkways – shows trend data during startup/shutdown. |
| LNG Plant Turboexpander Panel | Used for display of high-speed vibration and overspeed status before safety trips. |
| Test Stand / R&D Rotor Dynamics Lab | Provides real-time monitoring without computers – ideal for quick checks during bearing or seal testing. |
| Retrofit of Older 3500 Systems | Replaces obsolete CRTs or adds modern display to existing 3500 racks without upgrading entire system. |
Notes
The 147663-01 is the non-touchscreen version (display only). Touchscreen versions have different suffixes (e.g., -02, -03).
Requires an external 24 VDC power source – not powered by the 3500 rack backplane. Ensure the plant control power supply can provide 15 W.
Must be connected to a 3500 rack communication processor (e.g., 3500/20 Rack Interface Module, 3500/22M, TDXnet, or TDIX) via RS-232/422 cabling.
Configuration is done via 3500 System Configuration Software – display assignment and channel mapping are user-programmable.
Backlight life is approx. 50,000 hours (5.7 years continuous). Replacement backlights are available (recommended to order spare).
For outdoor or extreme ambient applications, a sun-shield or enclosure may be required due to 50°C max operating temperature.
