Bently Nevada 3500/22M 147364-01 Transient Data Interface Module

The Bently Nevada 3500/22M Transient Data Interface (TDI) Module, model 147364-01, is a key component in the 3500 Machinery Protection System, designed to act as the central communication link between the monitoring rack and external condition monitoring software such as System 1®. This enhanced version of the TDI integrates both the Rack Interface Module (RIM) and Transient Data Interface into a single unit, reducing hardware complexity while improving system communication, diagnostics, and monitoring capabilities.

The module allows high-speed, real-time transfer of both steady-state and transient vibration or position data. It plays a vital role in machinery diagnostics by capturing data during key events like startups, shutdowns, or system faults. The 147364-01 is installed in Slot 1 of the rack and supports redundant operation to ensure system reliability in mission-critical environments.
