Designed for demanding applications such as steam turbines, gas turbines, compressors, pumps, and generators, the module supports monitoring of radial vibration, shaft position, velocity, acceleration, and other critical mechanical parameters.

• Installations Requiring External Field Wiring Access:
The -02 configuration uses a Prox/Seismic I/O Module with external terminations, making it suitable for control cabinets where convenient field wiring access, simplified maintenance, and organized cable routing are important.

• Condition-Based Maintenance Platforms:
Integrated into the Bently Nevada 3500 Machinery Protection System, this module provides essential machine health information that supports predictive maintenance strategies and helps reduce unexpected equipment downtime.

Key Strengths at a Glance

• Four-Channel Proximitor/Seismic Monitoring:
Provides four independent monitoring channels for processing proximity and seismic transducer inputs, delivering vibration and position measurements for machinery protection applications.

• External Termination I/O Architecture:
The -02 option uses the Prox/Seismic I/O Module with external terminations, allowing field wiring connections to be separated from the rack module for improved installation flexibility.

• Multiple Measurement Functions:
Supports configurable monitoring functions including radial vibration, thrust position, differential expansion, eccentricity, REBAM, acceleration, velocity, shaft absolute, and circular acceptance region measurements.

• Programmable Alarm Processing:
The module compares conditioned signals against user-defined alarm setpoints, allowing operators to identify abnormal machine behavior and respond before serious equipment damage occurs.

• Reliable 3500 System Compatibility:
Designed for use within the Bently Nevada 3500 platform, it integrates with Keyphasor, communication, relay, and interface modules to create a complete machinery protection solution.
