The 3500/94‑145988‑01 is a VGA display module from the Bently Nevada 3500 Machinery Protection System. It is designed to provide local visualization of the machine condition, alarm and system event data, module / channel values, and rack‑view (in 3300 style / API‑670 style) for operators near the machinery or in a control room. It includes the display module with I/O card, supports touch screen operation, custom display pages, and can be installed at a distance from the 3500 rack using standard cabling.
Its role is to give clear, real‑time visibility of protection system status, allowing quicker diagnosis, monitoring, and response.

The 3500/94‑145988‑01 is used in places where local visibility of machine protection system information is important. Typical applications include:
Power generation plants, for turbine, generator, bearing, rotor health monitoring
Oil & gas facilities (onshore/offshore), compressors, pumps, rotating equipment
Petrochemical / Chemical plants, for monitoring reactors, heat exchangers, critical rotating machines
Steel, mining, manufacturing industries with heavy machinery, fans, blowers, motors etc.
Utilities, water treatment, or other industrial automation sites where safety and early fault detection are essential
High Clarity Display: VGA resolution and color display plus optional touch screen make reading data quick and intuitive
Custom Display Pages: Up to nine custom pages, allowing operators to tailor what they view (e.g. 1X vibration, gap values, channel summaries, etc.)
Rack‑View in 3300 / API‑670 Style: Makes it easier for those familiar with API‑670 / 3300 layout to orient themselves
Distance Flexibility: Display can be located some meters away from the rack (≈8 m) with standard cable; reduces clutter around the rack
Moderate Power Draw: At ~4.6 W, it does not add large heat or power load, aiding in efficiency and reliability
Solid Build & Components: Designed for industrial environment, including temperature and humidity tolerance
Ease of Configuration: Compatible with 3500 Rack Configuration Software; built‑in I/O card simplifies integration
