Product Description

The 3500/20 (125744-02) is the fundamental Rack Interface Module (RIM) for the Bently Nevada 3500 Machinery Protection System. Its primary role is to facilitate rack configuration and provide a communication gateway for display modules and external software.

While newer systems use the TDI, the 3500/20 remains a critical legacy component, supporting non-dynamic data collection and ensuring all monitor modules are properly initialized.
