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.
