The Bently Nevada 3500/22M Transient Data Interface (TDI) acts as the intermediary between the 3500 monitoring system and compatible software such as System 1 Condition Monitoring and Diagnostic software and 3500 System Configuration software. Combining the functionalities of a 3500/20 Rack Interface Module (RIM) with the data collection capabilities of a communication processor like TDXnet, the TDI facilitates seamless communication.

Installed in the slot adjacent to the power supplies of a 3500 rack, the TDI interfaces with M series monitors (3500/40M, 3500/42M, etc.), continuously gathering steady state and transient dynamic (waveform) data. This data is then transmitted via an Ethernet link to the host software. Refer to the Compatibility section for detailed information.

Standard static data capture capability is inherent to the TDI. However, utilizing an optional Channel Enabling Disk enables the TDI to capture dynamic and high-resolution transient data as well. Functioning as a communication processor within the 3500 rack, the TDI enhances data collection capabilities.

Although the TDI offers functionalities common to the entire rack, it does not form a part of the critical monitoring path and does not impact the proper operation of the overall monitor system for automatic machinery protection. Each 3500 rack necessitates one TDI or RIM, invariably occupying Slot 1 next to the power supplies.
