Bently Nevada 33500/22M 146031-01+288055-01 Transient Data Interface Module

The Bently Nevada 33500/22M Transient Data Interface Module (TDI), part numbers 146031-01 and 288055-01, is a high-performance communication and data interface unit designed for integration within the 3500 Machinery Protection System. This TDI version combines enhanced hardware capability with advanced transient data collection, supporting seamless communication with System 1® condition monitoring software.

Functioning as the system’s Rack Interface Module (RIM), it captures both steady-state and transient vibration or position data during machinery events such as startups, shutdowns, or malfunctions. With dual part numbers, this configuration includes both the core TDI module and associated terminal components for optimized installation and data transfer.

Installed exclusively in Slot 1 of the rack, the 33500/22M ensures centralized control, simplified configuration management, and high-resolution data communication for real-time diagnostics and predictive maintenance.
