Description

The Bently Nevada 3500/04 Internal Barriers are advanced intrinsically safe interface modules designed to enhance explosion protection for transducer systems integrated within the 3500 Machinery Protection System. These barriers are engineered as an internal rack solution, eliminating the performance limitations often associated with external barrier configurations.

The 3500/04 Internal Barriers ensure seamless compatibility with 3500 series monitors while maintaining full compliance with global hazardous-area certification standards. Their integrated design allows safe and reliable signal transmission from proximity, acceleration, velocity, and temperature sensors in explosive environments.

Unlike conventional isolation methods, the 3500/04 modules maintain system integrity without degrading monitoring accuracy, making them ideal for critical industrial protection applications where safety and precision are essential.

Applications

Power plants: Generator condition monitoring and protection control
Substations: Busbar protection, switching control, and signal acquisition
Chemical plants: Intrinsically safe process automation and monitoring
Steel plants: High-interference equipment control in harsh environments
Manufacturing: Automated production lines and robotics control systems

Features

Integrated rack-mounted intrinsic safety barrier design
No performance degradation to 3500 monitoring system
Supports multiple transducer types and industrial signals
Compatible with standard and TMR system configurations (with limits)
Hot-upgrade capability via I/O module replacement

Functions

Explosion protection for hazardous-area signal transmission
Safe signal isolation between field devices and control system
Supports vibration, speed, temperature, and process monitoring
Ensures compliance with global hazardous area standards
Maintains accurate real-time machinery condition monitoring

FAQ

Q1: What is the function of the 3500/04 Internal Barriers?
A1: They provide intrinsic safety protection for transducer signals connected to the Bently Nevada 3500 system in hazardous environments.

Q2: Which sensors are compatible with the 3500/04 system?
A2: It supports proximity probes, accelerometers, Velomitor sensors, RTDs, thermocouples, and process variable inputs.

Q3: Can internal barriers be mixed with standard modules?
A3: Yes, both standard and internal barrier modules can be installed in the same 3500 rack.

Q4: Do internal barriers affect system performance?
A4: No, they are designed to maintain full system performance without signal degradation.

Q5: Is an IS Earthing Module required?
A5: Yes, each rack using internal barriers must include a dedicated IS Earthing Module.
