Bently Nevada 136711-02 Internal Termination I/O Module with Intrinsic Safety Barriers
The Bently Nevada 136711-02 is a 4-channel I/O module for the 3500/42M monitor, featuring integrated intrinsic safety barriers. It allows for direct connection of sensors in hazardous areas without external isolation, supporting temperatures up to +85°C in critical industrial applications.
Technical Purpose and System Function
The Bently Nevada 136711-02 functions as a specialized I/O interface for the 3500/42M Proximitor Seismic Monitor. This module incorporates built-in intrinsic safety (IS) barriers, which limit the electrical energy entering hazardous areas to prevent the ignition of explosive atmospheres. By integrating these barriers directly into the I/O hardware, the system eliminates the need for external, bulky zener barriers or galvanic isolators. Consequently, the 136711-02 provides a streamlined, space-saving solution for connecting proximity probes and seismic sensors located in Zone 0, Zone 1, or Division 1 environments.

Operational Advantages and Industry Applications
Maintenance engineers prioritize the 136711-02 when monitoring rotating equipment in volatile environments, such as oil refineries, offshore platforms, and chemical gas plants. Because the internal barriers are factory-matched to Bently Nevada transducers, they ensure optimal signal integrity without the impedance mismatch often caused by third-party isolators. Furthermore, the internal termination design simplifies cabinet architecture by allowing technicians to land field cables directly on the 3500 rack. This configuration effectively protects critical assets including:
- Gas turbines in explosive processing zones
- High-pressure centrifugal compressors
- Hydrocarbon pumps and agitators
- Cooling tower fans in hazardous vapors
Installation and Safety Compliance
Technicians install the 136711-02 into the rear of the 3500 chassis, specifically in the slot corresponding to the 3500/42M monitor. To maintain the intrinsic safety rating, the user must follow strict separation rules between intrinsically safe and non-intrinsically safe wiring within the cabinet. Moreover, the module’s “hot-swappable” capability allows for safe replacement during active monitoring, provided the facility’s safety protocols allow for live maintenance. This integrated approach not only reduces installation costs but also ensures that the machinery protection system remains fully compliant with international explosive environment standards.
