The 288055-01 is the standard configuration kit for the Bently Nevada™ 3500/22M Transient Data Interface (TDI), bundling the main module with a dedicated isolation USB cable. This module acts as the core communication and data acquisition hub within the 3500 monitoring system, effectively bridging various M-Series monitoring modules within the rack (e.g., 3500/40M, 3500/42M, etc.) with host software platforms (e.g., System 1™ Condition Monitoring and Diagnostic software, 3500 System Configuration software).
Compared to the traditional 3500/20 Rack Interface Module (RIM), the TDI not only inherits all rack management functions but also integrates the data acquisition capability of a communication processor like TDXnet. It supports continuous, high-resolution steady-state and transient dynamic waveform data acquisition, uploading it to the host via Ethernet, providing the data foundation for equipment predictive maintenance and advanced diagnostics.
Integrated Design: Embeds the communication processor function within the 3500 rack, saving space for external equipment and wiring.
Non-Intrusive Monitoring: While providing rack-level functions, the module is not part of the critical monitoring and protection path, ensuring it does not affect the system's normal machinery protection functionality, thereby guaranteeing safety and reliability.
Standardized Slot: Occupies the same slot as the RIM module (Slot 1, adjacent to the power supply), facilitating easy upgrade and replacement.
Flexible Data Acquisition: Standard support for static data acquisition; unlocks dynamic and high-resolution transient data acquisition capability through an optional "Channel Enabling Disk."
II. Summary of Core Functional Features
This module integrates multiple core functions including data acquisition, communication, status indication, and system integration. Its key features are as follows:
Powerful Data Acquisition Capability:
Standard support for continuous steady-state data acquisition.
Unlocks high-resolution transient dynamic (waveform) data acquisition capability through an optional "Channel Enabling Disk," meeting the needs for fault diagnosis and in-depth analysis.
Rich Communication Interfaces:
Local Configuration: Front panel USB-B port, used with a dedicated isolation cable for local software configuration and data retrieval.
Network Communication: Supports 10Base-T/100Base-TX copper Ethernet (RJ-45) and optional 100Base-FX fiber optic Ethernet (MT-RJ), enabling high-speed, remote data transmission and configuration management.
Protocol Support: Compatible with BN Host Protocol and BN TDI Protocol over TCP/IP, ensuring seamless communication with host software.
Clear Status Indication:
The front panel is equipped with multiple dedicated LED indicators, intuitively displaying key statuses such as "OK (Operating Properly)", "TX/RX (Communicating)", "TM (Trip Multiply Mode)", and "CONFIG OK (Valid Configuration)", facilitating quick on-site inspection and fault localization.
Convenient System Integration:
Provides complete system contacts (Trip Multiply, Alarm Inhibit, Rack Reset) for interlocking with external control systems.
Features a programmable "OK Relay" for signaling the overall health status of the 3500 rack to a DCS or alarm system.
Supports external grounding of the Signal Common, enhancing system noise immunity and safety in complex electrical environments.
Safe and Reliable:
The module itself complies with multiple international electromagnetic compatibility (EMC) and electrical safety standards.
When combined with certified I/O modules and installed per specifications, it can meet requirements for use in hazardous areas such as Class I, Division 2 / Zone 2, making it suitable for demanding industrial environments like oil & gas and chemical processing.
III. Compatibility and Upgrade Guidance
3.1 System Compatibility
Must be used with M-Series Monitors (e.g., 3500/40M, 3500/42M, etc.).
When upgrading from a 3500/20 RIM to a 3500/22 TDI, verify compatibility of existing M-Series modules. Some early M modules may not be compatible with the TDI. Check BNTechsupport.com for the latest compatibility list.
3.2 Critical Upgrade Warning and Procedure
WARNING: If the old RIM I/O module is left in the rack when installing a new TDI, it will damage the TDI.
Mandatory Upgrade Order:
Remove the existing RIM main module.
Remove the existing RIM I/O module.
Insert the new TDI I/O module.
Insert the new TDI main module.
3.3 Network Requirements
To ensure system network security and stability, please refer to the 《3500 Hardening Guide》 (Document 106M9733) before deployment. This document can be requested at BNTechsupport.com.

V. Application Scenarios and Value
The 288055-01 TDI module is a core component for building modern, high-data-granularity condition monitoring systems. It is particularly suitable for:
Critical Rotating Machinery Protection and Monitoring: Such as steam turbines, gas turbines, compressors, pumps, and fans, providing millisecond-level capture of fault transients.
Predictive Maintenance and Advanced Diagnostics: By continuously acquiring steady-state and rich transient waveform data, it provides the data foundation for equipment health assessment, root cause analysis of faults, and remaining useful life prediction.
Process Industries and Energy Sector: Enables the transition from "reactive maintenance" to "predictive maintenance" in industries with extremely high demands for equipment reliability and safety, such as oil & gas, chemical processing, and power generation.
Integrated Monitoring Systems: Acts as a reliable data bridge between the 3500 hardware system and higher-level systems like Plant Historians, MES, or Enterprise Asset Management (EAM) systems.
