Bently Nevada 3500/20 Rack Interface Module

Description

The Rack Interface Module (RIM) serves as the primary interface to the 3500 rack, supporting a proprietary protocol for configuration and machinery information retrieval. Positioned in slot 1 of the rack, adjacent to the power supplies, the RIM facilitates seamless communication within the system. Compatible with Bently Nevada external communications processors like TDXnet, TDIX, and DDIX, the RIM enhances the versatility of the monitoring setup. While offering certain functionalities common to the entire rack, the RIM does not form a part of the critical monitoring path and does not impact the proper operation of the overall monitoring system. Each rack requires one RIM. For Triple Modular Redundant (TMR) applications, a TMR version of the RIM is necessary. In addition to standard functions, the TMR RIM performs "monitor channel comparison," comparing outputs from three redundant monitors. If deviations are detected beyond configured thresholds, the TMR RIM flags the monitor as in error and logs an event in the System Event List.
