Bently Nevada 3500/94 Display Module

The Bently Nevada 3500/94 VGA Display integrates reliable visualization with responsive touch-screen control and therefore supports the entire 3500 Machinery Protection System. The module works with the 3500/94 I/O card and a remote VGA monitor, which you may install up to 8 meters from the rack. This design improves panel layout flexibility while maintaining clear system diagnostics and fast navigation.

Key Functions

The 3500/94 Display shows complete system information, so technicians access event lists, module data, alarm summaries, and AP-670-style rack views without delay. The interface also provides nine customizable display pages that help engineers organize high-value vibration and system-health data.
