The Bently Nevada 288055-01 is the 3500/22M Standard Transient Data Interface (TDI) Module, a critical component of the 3500 Series Machinery Protection System. It serves as the primary communication gateway and data acquisition interface between the 3500 monitoring system and external machinery management software such as GE's System 1* . The TDI collects both steady-state and transient waveform data from the 3500 rack's monitoring modules (including vibration, position, and temperature monitors) and transmits it via high-speed Ethernet for analysis and diagnostics. Importantly, it operates independently of the critical monitoring path, ensuring that machinery protection functions continue uninterrupted even if the TDI loses communication.

The Bently Nevada 3500/53-03-00 is a highly reliable Electronic Overspeed Detection System designed for the 3500 Series Machinery Protection System. This module provides critical overspeed protection for rotating machinery such as steam and gas turbines, compressors, generators, and turbo-expanders by continuously monitoring rotational speed and initiating a trip signal when preset limits are exceeded. The -03-00 configuration indicates a Three-Channel System with no additional agency approvals. This triple-redundant architecture enables voting logic configurations (2-out-of-2 or 2-out-of-3) to prevent false trips while ensuring genuine overspeed events are reliably detected.

The Bently Nevada 3500/32 125720-01 is the I/O termination module that completes the 3500/32 4-Channel Relay Module system. Together with the 149986-02 (or 125712-01) main logic board, this assembly provides four independent, programmable relay outputs that serve as the critical link between the 3500 monitoring system and external control devices . As a full-height module designed for the 3500 Series Machinery Protection System, it translates alarm logic states—such as Alert, Danger, or Not OK conditions—from monitoring modules into physical dry contact outputs. These contacts can directly drive alarm indicators, sirens, machine trip circuits, or PLC/DCS inputs, making it an essential component for hard-wired machinery protection and automated control applications in turbines, compressors, and generators.

The Bently Nevada 3500/25 149369-01 is a half-height, two-channel Enhanced Keyphasor Module for the 3500 Series Machinery Protection System. Its core function is to receive input signals from proximity probes or magnetic pickups and convert them into precise digital Keyphasor signals. These signals indicate exactly when a Keyphasor mark on a rotating shaft passes the sensor, providing a critical timing reference used to measure rotational speed, vibration phase, and other vector parameters.

The Bently Nevada 3500/22M 138607-01 is a Transient Data Interface (TDI) module for the 3500 Series Machinery Protection System. Its core function is to serve as the primary communication bridge between the 3500 monitoring rack and upper-level software, such as System 1® machinery management software and 3500 System Configuration software. It combines the functionality of the earlier 3500/20 Rack Interface Module (RIM) and a communication processor like TDXnet, consolidating data acquisition and system interface tasks into a single module.

The Bently Nevada 3500/22M-01-01-00 is a Transient Data Interface (TDI) module for the 3500 Series Machinery Protection System. Its core function is to serve as the primary communication bridge between the 3500 monitoring rack and upper-level software, such as System 1 machinery management software and 3500 System Configuration software. By combining the functionality of the earlier 3500/20 Rack Interface Module (RIM) and a communication processor like TDXnet, it consolidates data acquisition and system interface tasks into a single module.

The Bently Nevada 3500/42M-01-00 is a four-channel Proximitor Seismic Monitor from the 3500 Series Machinery Protection System. Its core function is to continuously monitor the vibration and position of critical rotating machinery by accepting inputs from proximity and seismic transducers. It conditions these signals and compares them against user-programmable alarms to provide essential protection and status information.

The Bently Nevada 3500/94 is a dedicated VGA Display Router and Human-Machine Interface (HMI) module for the 3500 Machinery Protection System. It provides a high-fidelity visual interface, allowing operators to view real-time machinery data, alarm event lists, and system status directly at the rack or from a remote terminal . This module acts as the central visualization hub, translating complex machinery data from the 3500 rack into intuitive graphics, bar graphs, and alarm lists on a standard color VGA monitor. It is designed for API 670-compliant monitoring architectures.

The Bently Nevada 3500/61 is a high-performance 6-channel temperature monitoring module designed for the 3500 Machinery Protection System. This module provides continuous, real-time temperature monitoring for critical rotating machinery, accepting inputs from both Resistance Temperature Detectors (RTDs) and Thermocouples (TCs) . The 3500/61 conditions these temperature signals and compares them against user-programmable alarm setpoints. Its key distinguishing feature is the provision of recorder outputs for each of its six channels , making it the preferred choice for applications requiring analog output for trend recording or DCS integration.

The Bently Nevada 3500/42M 176449-02 is a four-channel Proximitor*/Seismic Monitor from the renowned 3500 Series Machinery Protection System. Its core function is to continuously monitor the vibration and position of critical rotating machinery, such as turbines, compressors, and generators. It achieves this by accepting inputs from proximity and seismic transducers, conditioning the signals, and comparing them against user-programmable alarms to provide essential protection and status information to operators.

The Bently Nevada 3500/40M 176449-01 is a four-channel Proximitor Monitor from the 3500 Series Machinery Protection System . Its core function is to receive signals from Bently Nevada proximity transducers, condition them to provide essential vibration and position measurements, and compare these against user-programmable alarms to protect critical rotating machinery.

The Bently Nevada 3500/33 16-Channel Relay Module is a full-height output module for the 3500 Series Machinery Protection System. Its core function is to provide 16 independent relay outputs that translate alarm conditions from monitor modules into actionable control signals—such as triggering alarms, activating shutdown sequences, or controlling external equipment.
