3500/20 125744-02 Bently Nevada Standard Rack Interface Module with
125768-01 RIM I/O Module
Product Overview
The Bently Nevada 3500/20-01-02-00 125744-02 is a high-performance
Rack Interface Module (RIM) designed specifically for the Bently
Nevada 3500 series machinery condition monitoring system. This
module serves as the primary communication bridge between the rack
and external devices (such as a PC or transient data interface
(TDI)), supporting data acquisition, configuration management, and
system communication. It is a key component in building predictive
maintenance systems for industrial rotating machinery.
Core Functions
Communication Hub: Supports RS-232/RS-485 serial and Ethernet
communications, and is compatible with protocols such as TCP/IP and
Modbus TCP, enabling real-time data transmission and remote
monitoring.
Plug-and-Play: The modular design and DIN rail mounting support
allow for seamless integration into existing 3500 system racks,
simplifying deployment. High Reliability: Operating temperature
range -40°C to +85°C, and EMI-resistant design, suitable for harsh
industrial environments such as power plants, petrochemicals, and
metallurgy.
Redundancy Support: In a TMR (triple redundant) configuration, it
can be expanded to a TMR RIM version. By comparing the outputs of
redundant monitors, it automatically identifies anomalies and
triggers alarms, ensuring system safety.

Application Scenarios
Rotating Machinery Monitoring: Real-time collection of parameters
such as vibration, displacement, and speed. Suitable for critical
equipment such as steam turbines, compressors, pumps, and fans.
Predictive Maintenance: Trend analysis and threshold alarms enable
early detection of potential faults such as bearing wear, shaft
misalignment, and imbalance.
System Integration: Supports integration with DCS, SCADA, MES, and
other platforms, facilitating factory intelligent upgrades.
