Description
Product Overview
The Bently Nevada 3500/05-01-02-00-00-01 is a full-size 19-inch System Rack designed for the 3500 Machinery Protection System. It provides the mechanical mounting structure and internal backplane required for installing 3500 monitoring modules, power supplies, rack interface equipment, relay modules, communication modules, and other compatible components.
This configuration uses a 19-inch rack with 14 available monitor module slots. The rack-mounted design is intended for installation in a standard 19-inch EIA equipment cabinet or rack.
The rack is an important part of the 3500 system because the individual modules plug into the rack backplane, allowing system modules to communicate with one another while distributing power from the installed power supply modules.
The supplied identification may include:
- PWA: 138607-01 AG
- PWB: 125794-01
- System Rack: 3500/05-01-02-00-00-01
When replacing an existing rack, the complete 3500/05 ordering code and the board markings should be checked rather than ordering by “3500/05” alone.

The 3500/05 family is available in different rack sizes and mounting configurations. For this specific ordering code, the 01 rack-size option identifies the 19-inch rack with 14 module slots, while 02 identifies the full-size rack-mount option.
System Function
The 3500/05 is not a vibration monitor by itself. It is the physical and electrical platform on which the 3500 monitoring system is assembled.
A typical system architecture is:
Sensors → I/O Modules → 3500 Monitor Modules → 3500/05 Backplane → Rack Interface / Communication → Control or Monitoring System
The rack provides the common backplane connection between installed modules. It also works with the 3500 power supply architecture to distribute power to the modules installed in the rack.
A standard full-size 3500 rack reserves positions for the power supply and rack interface functions, with the remaining positions used for monitoring, relay, Keyphasor, display, and communication modules according to the system configuration.
Typical Applications
The 3500/05 rack is commonly used as part of machinery protection and condition monitoring systems for:
- Steam turbines
- Gas turbines
- Compressors
- Pumps
- Generators
- Motors
- Fans
- Gearboxes
- Rotating process equipment
- Oil & gas machinery
- Power generation equipment
- Industrial rotating machinery
Bently Nevada describes the 3500 platform as a continuous online machinery monitoring and protection system, with the 3500/05 System Rack serving as the common rack platform for the monitoring modules and power supplies.
Compatible 3500 System Modules
Depending on the installed system configuration, the rack can accommodate compatible modules such as:
- 3500/15 Power Supply
- 3500/20 Rack Interface Module
- 3500/22M Transient Data Interface
- 3500/25 Keyphasor Module
- 3500/32 Relay Module
- 3500/34 TMR Relay Module
- 3500/42M Proximitor/Seismic Monitor
- 3500/50 Tachometer Module
- 3500/60 Temperature Monitor
- 3500/65 Temperature Monitor
- 3500/72M Reciprocating Rod Position Monitor
- 3500/92 Communication Gateway
- 3500/93 Display Module
- Other compatible 3500 monitor and interface modules
Actual compatibility depends on the rack revision, module revision, system configuration, and installed I/O assemblies.
Installation & Replacement Guide
1. Confirm the Rack Identification
Before installation, verify:
- 3500/05-01-02-00-00-01
- PWA 138607-01 AG
- PWB 125794-01
- Rack size and mounting configuration
- CE option
- Existing system revision
Do not assume that every 3500/05 rack has the same mechanical configuration.
2. Check the Cabinet
The full-size version is designed around a 19-inch EIA rack installation. Confirm that the cabinet has sufficient width, depth, ventilation, and clearance for the rack and installed modules.
3. Inspect the Backplane
Before inserting modules, inspect the backplane for:
- Bent contacts
- Damaged connectors
- Contamination
- Corrosion
- Loose hardware
- Physical cracks
- Signs of overheating
The backplane is part of the electrical interconnection between the 3500 modules, so connector condition is important.
4. Install the Rack
Secure the rack firmly to the cabinet or equipment frame. Make sure the rack is mechanically supported before installing the heavier modules.
5. Install Power Supplies and Interface Modules
Install the appropriate 3500 power supply and rack interface equipment in their designated positions according to the system documentation.
6. Install Monitor Modules
Insert each 3500 monitor module into its assigned position. Check that the module is fully seated before tightening the retaining hardware.
7. Verify System Configuration
After installation, verify:
- Module positions
- I/O module compatibility
- Rack address/configuration
- Power supply arrangement
- Communication interface
- Alarm configuration
- System monitoring status
Maintenance Notes
The rack itself contains no conventional programmable logic function. Most troubleshooting should therefore focus on the physical and electrical condition of the rack and backplane.
Recommended inspection points include:
- Backplane connector condition
- Module seating
- Rack grounding
- Power supply connections
- Signs of overheating
- Corrosion or contamination
- Mechanical mounting
- Loose screws or hardware
- Compatibility of installed modules
If a complete 3500 system intermittently loses multiple modules at the same time, inspect the rack/backplane and power distribution before replacing individual monitor modules.
Compatibility & Replacement Notes
The complete part number matters when replacing a 3500/05 rack.
For example, the following codes can represent different configurations:
3500/05-01-02-00-00-01
19-inch full-size rack, rack-mount configuration, CE option.
A 3500/05 with a different rack-size, mounting, agency approval, or compliance suffix should not automatically be considered interchangeable.
Bently Nevada also offers different 3500 rack formats, including full-size and mini-rack versions as well as rack, panel, and bulkhead mounting arrangements.
FAQ
Q1: Is the 3500/05 a monitoring module?
No. It is the system rack/backplane platform used to install and interconnect compatible 3500 modules.
Q2: How many monitor module slots does this version provide?
The 01 rack-size option is the 19-inch full-size rack with 14 available monitor module slots.
Q3: Can a 7-slot mini-rack replace this unit?
Not as a direct mechanical replacement. The mini-rack has a different physical size and module capacity.
Q4: What are PWA 138607-01 AG and PWB 125794-01?
They are board identification markings associated with the rack assembly. They should be recorded when verifying a replacement.
Q5: Can I install any 3500 module in any slot?
Not necessarily. Power supply and rack-interface positions follow the 3500 rack architecture, while the remaining positions depend on the module type and system configuration.
Q6: Does the rack provide the vibration measurement itself?
No. Vibration, position, speed, temperature, and other measurements are handled by the appropriate 3500 monitor and I/O modules installed in the rack.

Inspection Before Shipment
For an industrial spare part, the rack should be inspected before packing:
- Verify the complete model number
- Verify PWA and PWB markings
- Check rack dimensions and mounting holes
- Inspect the backplane connectors
- Check for bent or damaged contacts
- Inspect for corrosion or contamination
- Check mechanical mounting hardware
- Confirm all supplied accessories
- Photograph nameplates and board markings
- Perform electrical continuity checks where applicable
- Record inspection results before shipment
For replacement orders, the safest approach is to compare the customer’s existing rack label and board markings with the replacement unit before dispatch.
