Product Description The Bently Nevada 3500/22M 138607-01 is the primary communication and data processing interface for the 3500 Series Machinery Protection System. The TDI (Transient Data Interface) functions as the bridge between the 3500 rack and the System 1™ condition monitoring and diagnostic software. Unlike standard interface modules, the 22M variant has the onboard capability to capture high-resolution transient data during machine startup and coast-down, as well as steady-state dynamic data (waveforms). It processes signals from all other modules in the rack, providing critical diagnostics for rotating machinery without compromising the primary protection functions.
Application Areas This interface is a fundamental component in large-scale industrial machinery protection environments, including power plants, refineries, and offshore platforms. It is specifically used to monitor steam turbines, gas turbines, centrifugal compressors, and high-speed pumps, where detailed vibration analysis and transient event logging are necessary for predictive maintenance.

Operational Precautions
- The TDI must be installed in the slot immediately adjacent to the power supplies (Slot 1) for proper rack communication.
- Ensure the “Rack Key” on the backplane is correctly aligned to prevent physical damage to the module pins during insertion.
- The module should be “Locked” via the front-panel key switch or software configuration to prevent unauthorized setpoint or configuration changes.
- Always backup the rack configuration file using the 3500 Rack Configuration Software before performing a firmware upgrade or module replacement.
