Core board
The Bently Nevada 3500/05-01-01-00-00-00 System Rack represents the essential hardware chassis that brings together every component of a 3500 Machinery Protection System. This specific configuration combines a full-size, 19-inch EIA rack with a panel-mount format, providing 14 available module slots for housing monitor modules, power supplies, and communication gateways.
A Centralized Backbone for Critical Monitoring
The primary function of the 3500/05 rack is to provide a centralized enclosure where all 3500 series monitoring modules and rack power supplies reside. Beyond mere physical mounting, the rack delivers backplane communications that allow installed modules to exchange data with one another and receive the power they require for operation. This integrated approach simplifies system architecture and ensures that vibration, position, speed, and temperature measurements from a single machine train can be processed within one coordinated platform.

Slot Allocation and System Architecture
A critical architectural rule governs every 3500/05 rack: the power supply modules and the Rack Interface Module (RIM) must occupy the far left positions. This fixed allocation ensures that power distribution and backplane communication are established before any monitoring modules are inserted.
The remaining 14 rack positions are available for any combination of 3500 modules. This includes the 3500/40M Proximitor Monitor, 3500/42M for velocity and acceleration, 3500/50M Tachometer Module, relay modules, and communication gateways. Engineers can populate the rack according to the specific measurement requirements of each machine, creating a tailored protection system within a single chassis.
Ordering Code Breakdown
The full ordering structure follows the pattern 3500/05-AXX-BXX-CXX-DXX-EXX. For the 3500/05-01-01-00-00-00 model, the segments decode as follows:
A = 01: Full-size rack, 19-inch EIA, 14 module slots
B = 01: Panel mount option for full-size rack
C = 00: No agency approval option selected
D = 00: No reserved configuration
E = 00: No European compliance option
The trailing zeros indicate a standard configuration without specialized certifications. This variant is suitable for installations where specific hazardous area approvals or European compliance markings are not required.
Key Considerations for System Design
Several architectural constraints should be understood before specifying the 3500/05-01-01-00-00-00. If internal barriers are to be installed, the 3500/04-01 Internal Barrier Earthing Module requires a dedicated rack position for connecting the IS earth. The 3500/06 Weatherproof Housing is not compatible with bulkhead-mounted racks, though the panel mount configuration of this model avoids that restriction.
For Mini-Rack installations in EIA rails, a 144863-01 Adapter Panel is required to convert the 12-inch frame to the 19-inch standard, but the full-size rack eliminates this need.
The rack operates within a temperature range of -20°C to +65°C, consistent with the environmental specifications of the 3500 system platform. The 3500 system as a whole is designed to comply with API 670, the globally recognized standard for machinery protection systems.
Conclusion
The 3500/05-01-01-00-00-00 System Rack is the foundational hardware decision for any 3500-based monitoring installation. Its 14-slot capacity, panel-mount format, and rear-access wiring architecture provide a flexible framework for deploying vibration, position, and speed monitoring across critical rotating machinery. For engineers configuring a protection system, this rack represents the starting point—the chassis that determines module capacity, mounting strategy, and long-term expandability.
