Description
The 3500/05-01-02-00-00-01 is the Bently Nevada 3500 Series System Rack in its full-size, 19-inch EIA, rack-mount, CE-compliant form – the welded skeleton and backplane that turn a handful of monitoring modules into a certified machinery protection system. It is not a sensor and it is not a monitor; it is the chassis that decides how many channels you can protect, how the modules talk to each other, and whether a failed power supply can be swapped before the turbine notices.
Fourteen module positions, a dedicated left-hand zone for the power supplies and the rack interface, a high-density backplane that distributes dc rails and proprietary inter-module data, and a rear-access I/O scheme that keeps the control-room front panel clean. That is the whole proposition in one breath. Decode the suffix and it reads like a build sheet: 01 = 19-inch, 14-slot frame; 02 = rack-mount on standard EIA rails; 00 = no agency approval option on the chassis; 00 = reserved; 01 = CE European-compliance configuration .
Application Scenarios
Imagine a 350 MW combined-cycle plant in the middle of a forced outage. The #1 gas turbine’s TSI cabinet has grown, quietly, over eleven years: four radial vibration pairs on the 3500/42M, an axial-position channel, a 3500/53 overspeed, a 3500/32 relay bank, a 3500/25 Keyphasor, and a 3500/22M TDI feeding dynamic data to the analyst’s workstation. Someone proposes adding a 3500/65 temperature monitor for the new bearing-PT100s, and the old seven-slot mini-rack is already full. The answer is not a second cabinet and a rewire – it is a 3500/05-01-02-00-00-01 slid into the same 19-inch bay, using the identical hole pattern, cable routing and grounding philosophy the original EPC already documented.
The pain it removes is the one that keeps protection engineers awake: a protection chassis that forces compromises. With only seven slots you start trading a relay channel for a temperature channel, or you push the second power supply out and pray the first one holds. With fourteen, the 3500/05-01-02-00-00-01 lets you keep the redundant 3500/15 pair, the RIM or TDI in its ordained leftmost position, every monitor on its own card, and still have headroom for the next outage’s “while we’re in there” addition. No re-baselining the alarm philosophy, no new cable schedule, no HAZOP re-open because the rack footprint changed.
Parameter
| Parameter | Value / Description |
|---|---|
| Product Model | 3500/05-01-02-00-00-01 |
| Manufacturer | Bently Nevada, a Baker Hughes company (legacy GE/Bently Nevada supply chain) |
| Product Category | System rack / instrument chassis with integral backplane (3500 Series Machinery Protection & Condition Monitoring System) |
| Decoded option string | 3500/05-AA-BB-CC-DD-EE → AA 01 19-inch rack, 14 slots; BB 02 rack-mount (19 in EIA rails); CC 00 no agency approval option; DD 00 reserved; EE 01 CE European-compliance configuration |
| Module capacity | 14 module slots total. Power supplies and the Rack Interface Module/TDI occupy the dedicated far-left positions; the remaining positions take monitors, relays, Keyphasor, comms and display modules |
| Backplane | Integral high-density pin-array backplane carrying internal dc power distribution (+5 V, ±15 V, +24 V rails) plus the proprietary inter-module communication bus – no external ribbon cables to fatigue |
| Mounting | 19-inch EIA rack-mount, rear access for I/O and wiring terminations. Front panel presents only module faces and status LEDs |
| Overall dimensions | 482.60 mm W × 349.25 mm D × 265.94 mm H (19.000 × 13.750 × 10.470 in). Depth grows to ≈422.9 mm (16.650 in) when internal barriers are fitted |
| Weight | ≈4.5 kg empty chassis (shipping mass varies with packing and fitted modules; fully populated racks commonly land in the 13–20 kg class) |
| Chassis construction | Heavy-gauge aluminium / structural sheet-metal frame with a dedicated copper chassis-earth stud – the single point that keeps RFI from coupling into the backplane |
| Power architecture | Accepts one or two 3500/15 AC/DC power-supply modules (redundant pair supported). Rail health is reported rack-wide rather than per card |
| Module serviceability | Live module replacement supported – monitors, relays and I/O can be changed without shutting the protected machine down, provided the architecture was designed for it |
| Internal-barrier provision | Racks hosting internal barriers require a 3500/04-01 Internal Barrier Earthing Module in its own dedicated position; plan the slot budget before you populate |
| Environmental, operating | 0 °C to +60 °C (some 3500 documentation and fitted-module datasheets extend to −20/−30 °C; treat the tighter 0–60 °C band as the conservative chassis figure) |
| Environmental, storage | −40 °C to +85 °C; 5% to 95% relative humidity, non-condensing |
| EMC / safety basis | EN 55011 / CISPR 11, EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions); EN 61010-1 electrical safety; CE-marked in the 01 configuration |
| Hazardous-area status | Chassis itself is non-incendive infrastructure; hazardous-area approvals (CSA C/US, ATEX/IECEx Zone 2, Class I Div 2) are inherited from the fitted monitors and barriers – this unit is option 00, so confirm each card’s certificate before the Ex drawing is signed |
| System standard | API 670 machinery protection architecture; combines with appropriately rated 3500 monitors for SIL-capable protection schemes (claim is system-level, not a chassis-alone rating) |
| Compatibility | All 3500-generation monitors and I/O: 3500/40M, /42M, /45, /50, /53, /60, /65, /32, /25, /22M, /20, /92 and the 3500/93 display; not a drop-in mechanical fit for the 12-inch mini-rack without the 144863-01 adapter route |
| Lifecycle note | Legacy 3500 platform; new-surplus and tested refurbished stock are the normal supply path. Verify label, serial number, revision and backplane condition before a live-spare commitment |
