3500/20 125744-02 Bently Nevada Standard Rack Interface Module with 125768-01 RIM I/O Module
The Bently Nevada 3500/20 Rack Interface Module (Part Number: 125744-02) is a critical component of the 3500 Machinery Protection System, providing essential communication, power distribution, and system coordination within a 3500 rack-based monitoring and protection architecture. Designed for continuous, high-reliability operation in demanding industrial environments—including oil & gas, power generation, chemical processing, and heavy manufacturing—this module serves as the central hub that links 3500 I/O modules, sensors, and external control systems via RS-232, RS-485, and Modbus protocols.
As the primary interface between the 3500 rack and higher-level systems such as SCADA, DCS, or PLCs, the 3500/20 125744-02 enables real-time data access, alarm reporting, configuration uploads, and remote diagnostics. It also supplies regulated ±24 V DC sensor power to connected transducers and ensures synchronized operation across all modules in the rack through the 3500 backplane. With dual independent communication ports and support for redundant configurations, this module enhances system availability and simplifies integration into modern asset health monitoring strategies.
