Bently Nevada 3500/20 Rack Interface Module (RIM I/O, Part No. 135031-01)

Product Overview

The 3500/20 is a high-performance monitoring module developed by Bently Nevada as part of the 3500 Series machinery monitoring and protection system. The 135031-01 is the Rack Interface Module (RIM) with Modem Interface — the primary rack-interface I/O module for the 3500 rack. It serves as the bridge between the 3500 rack system and external control systems, enabling rack configuration and retrieval of machinery information.

3500/20 135031-01

Key Functions

• Acts as the master interface for the 3500 rack, supporting system configuration and mechanical-information retrieval.
• Provides data acquisition, configuration management, and communication between the monitoring system and external devices.
• Installed in slot 1 of the rack (adjacent to the power supply).
