Description

Overview

The 3500/05 system rack from Bently Nevada serves as the structural and electrical backbone of the 3500 Machinery Protection System. It is responsible for mechanically supporting all monitoring modules while ensuring stable power delivery and high-speed internal communication through a dedicated backplane architecture.

This rack does not perform signal processing itself; instead, it provides the platform required for all 3500 system modules to operate as an integrated protection and monitoring system.

Mechanical Structure & Configuration

The rack is engineered in two standardized formats to support different installation requirements:

Full-size rack (19-inch EIA)

• Supports up to 14 module slots

• Designed for standard industrial control cabinet integration

• Provides full rear access for wiring and maintenance

Mini rack (12-inch format)

• Supports up to 7 module slots

• Compact design for space-constrained installations

• Rear wiring access maintained for serviceability

Mini rack configurations are not compatible with bulkhead mounting arrangements.

Mounting Options

The system rack supports multiple installation methods depending on site design:

• Panel mounting using rectangular cut-outs with rear access wiring

• Standard 19-inch rack mounting on EIA rails

• Bulkhead mounting with front-access wiring for tight enclosures

Each mounting method is selected based on cabinet architecture and maintenance accessibility requirements.

Electrical Architecture

• Integrated backplane for module-to-module communication

• Centralized power distribution through installed power supplies

• Left-side reserved slots for system-critical modules:

• Rack Interface Module (RIM)

• Power supply units

Remaining slots are configurable for vibration monitors, relay modules, and communication interfaces within the 3500 platform.

Environmental & Compliance Standards

• Operating temperature range: –20°C to +65°C

• EMC compliance:

• EN 61000-6-2 (industrial immunity)

• EN 61000-6-4 (industrial emissions)

• Electrical safety standard: EN 61010-1

• FCC Part 15 compliance for electromagnetic regulation

Hazardous Area Certifications

The rack is suitable for deployment in classified environments when used with approved system components:

• Class I, Division 2, Groups A–D, T4

• ATEX / IECEx: II 3G Ex nA nC ic IIC T4 Gc

System Integration Notes

• Internal barrier configurations require dedicated grounding via 3500/04-01 earthing module

• Mini rack configurations require compatible system software version 2.70 or later

• Some display and enclosure accessories may have compatibility constraints depending on rack type

Application Areas

• Gas and steam turbine protection systems

• Compressor and rotating equipment monitoring

• Refinery and petrochemical machinery infrastructure

• Power generation condition monitoring systems

• Large-scale machinery protection architectures requiring modular expansion

FAQ

Q1: Does the 3500/05 perform vibration measurement?
No. It functions purely as a rack platform for housing and interconnecting monitoring modules.

Q2: Can different module types be mixed in one rack?
Yes. The rack supports mixed configurations of monitors, relays, and communication modules within available slots.

Q3: Is the rack expandable after installation?
Yes. System expansion is supported as long as slot capacity and power budget are respected.
