Description

The Bently Nevada 3500/20 Rack Interface Module (RIM) serves as the central communication gateway within the 3500 Machinery Protection System, providing seamless interaction between rack components and host software. Designed for reliable industrial monitoring environments, the 3500/20 enables efficient rack configuration, data acquisition, and system diagnostics while maintaining stable communication across connected monitoring modules.

As a critical system interface, the 3500/20 supports multiple communication options including RS232, RS422, modem, and data management interfaces. It is compatible with external communication processors and monitoring platforms, allowing users to access machine condition data, alarm information, and configuration parameters from local or remote locations.

For high-availability applications, the 3500/20 is also available in a Triple Modular Redundant configuration. Together with related modules such as 3500/22M, 3500/25, and 3500/32, it forms a scalable machinery protection solution for turbines, compressors, generators, and other critical rotating equipment in demanding industrial environments.
