Description
Product Description
The Bently Nevada 3500/22M 164466-01 Transient Data Interface (TDI) serves as the central communications and data acquisition gateway for the 3500 Machinery Protection System. It consolidates rack-level communication, configuration control, and high-resolution vibration data transfer into a single integrated module.
Functionally, this module replaces the legacy rack interface role while extending capability into advanced transient data capture, enabling detailed machinery behavior analysis during start-up, coast-down, and process disturbances. It is engineered for continuous integration with System 1 condition monitoring software.
Designed for reliability in critical rotating equipment environments, the module ensures that both static and dynamic machine data are reliably transmitted, stored, and synchronized across the monitoring architecture.
