Product Overview

The Bently Nevada 128718-01 is a specialized External Termination Block designed to facilitate the integration of external Keyphasor signals into the Bently Nevada 3500 Machinery Protection System. In complex turbomachinery applications, the Keyphasor signal—which provides a once-per-turn phase reference—is often generated by a sensor located remotely from the monitoring rack or by a third-party device. The 128718-01 serves as a robust interface, allowing these external signals to be safely and reliably connected to the 3500/25 Keyphasor Module or compatible monitor cards.

This termination block is engineered to ensure signal integrity and system protection. It typically houses the necessary circuitry or connection points to adapt the external Keyphasor input to the logic levels required by the Bently Nevada 3500 system. By utilizing the 128718-01. users can isolate the monitoring rack from field wiring issues and provide a secure, organized connection point. The 128718-01 is essential for applications requiring precise phase measurement for balancing, rub detection, and eccentricity monitoring, ensuring that the protection system receives a clean, accurate trigger signal.
