The Bently Nevada 138607-01 3500/22M Standard Transient Data Interface (TDI) Module is a crucial component for seamlessly connecting the 3500 monitoring system to GE’s System 1 machinery management software. The TDI combines the functionality of a 3500/20 Rack Interface Module (RIM) with advanced communication processors like TDXnet to collect and transfer both steady-state and transient data from critical machinery.

Positioned within the RIM slot of a 3500 rack, the TDI works in conjunction with M series monitors (e.g., 3500/40M, 3500/42M) to continuously gather and transmit waveform data over an Ethernet link to the host software. While the standard TDI captures static data, an optional Channel Enabling Disk allows for the capture of dynamic or transient data, enhancing the system’s data acquisition capabilities.

With improvements over previous communication processors, the TDI ensures smooth integration and optimal data transfer performance. It operates independently of the critical monitoring path, meaning it has no impact on the overall monitoring system’s function, ensuring the safety and reliability of operations.

For Triple Modular Redundant (TMR) applications, the TDI supports monitor channel comparison, providing monitor voting based on predefined settings. It flags discrepancies between redundant monitors, ensuring the highest level of accuracy and system reliability.
