Description
The Bently Nevada 135489-02 I/O Module with Internal Barriers provides intrinsically safe signal isolation for 3500 system transducers. Moreover, it integrates internal barriers and terminations to protect hazardous area connections. This module supports 2 Proximitor/Acceleration channels plus 2 Velomitor channels, ensuring reliable industrial monitoring performance.
Functional Highlights
- Explosion Protection: Internal barriers provide intrinsic safety for hazardous area wiring.
- IS Earthing Compliance: The 3500/04-01 IS Earthing Module ensures proper grounding in each rack.
- Rack Flexibility: Compatible with standard I/O modules, maintaining safe separation between hazardous and safe circuits.
- Maintenance-Friendly Layout: Modular depth and positioning simplify online access during routine inspection.

System Integration
Internal Barrier I/O Modules can coexist with standard I/O modules without compromising safety. In addition, grouping barrier modules in adjacent positions simplifies installation, and leaving at least two empty rack positions between modules ensures easy online maintenance access. External terminations are not suitable for these modules, as intrinsically safe multi-core wiring
