1. Basic Info / Brand / Series
-
Brand: Bently Nevada
-
Series / Family: 3500 Machinery Protection System
-
Model / Part Number: 3500/04 138257‑01
-
Type: Internal Barrier / I/O / module (earthing / grounding / isolation barrier)
-
Role: Provides internal signal barrier / earthing interface / I/O functionality and isolation within a 3500 rack
2. Product Introduction
The 3500/04 (138257‑01) is a module in the Bently Nevada 3500 series, commonly used as an internal barrier module or earthing front panel / grounding interface in machinery protection racks. It helps manage grounding, provide isolation between signals, and act as an interface point for internal wiring or external earthing. In a 3500 rack, the internal barrier module ensures that sensitive signals are properly referenced, noise is minimized, and safety is maintained through controlled grounding paths.
It fits into the modular rack architecture and works with other 3500 modules by connecting through the rack backplane. Its internal barrier circuits help isolate zones and protect against electrical interference or ground loop issues.
Some vendors list this as a front panel earthing module with physical dimensions and channel parameters. For example:
-
Weight: ~0.201 kg (i.e. 201 g) as per some listings.
-
Dimensions: 241 mm × 24.4 mm × 103.1 mm (9.50 in × 0.96 in × 4.06 in) in one listing.
-
Operating temperature: –40 °C to +85 °C (some vendor spec for internal barrier module)
These suggest that the module is fairly slender in form and lightweight.
3. Applications
The 3500/04 (138257‑01) module is typically used in:
-
Machinery protection racks for turbines, compressors, pumps, and generators
-
As an internal barrier / grounding module to isolate signal zones
-
In modular 3500 systems to support earthing / grounding integrity
-
Integration with proximity probes, vibration sensors, speed sensors, and protective relay modules
-
Retrofit or replacement within existing 3500 racks
-
Applications demanding reliable signal isolation, low noise, and proper ground reference
4. Advantages / Strengths
Key benefits of this module include:
-
Signal isolation — acts as a barrier to prevent interference and ground loops
-
Compact and lightweight — minimal added load and space usage in a rack
-
Wide temperature range — capable of –40 °C to +85 °C in some vendor claims
-
Low weight — one listing shows only ~0.201 kg, reducing mechanical strain
-
Compatibility with other 3500 modules and rack architecture
-
Standard form factor — fits existing slots / backplanes
-
Improved reliability and safety — ensures controlled grounding paths
-
Ease of replacement — modular, plug‑in design
-
Vendor support — recognized as a correct part for 3500 systems
-
Reduced noise / interference — ideal in environments with sensitive signals
