126648-02 | Bently Nevada Isolated Keyphasor I/O Module

The Bently Nevada 126648-02 Isolated Keyphasor I/O Module is a specialized component in the 3500 Series monitoring system, designed for scenarios requiring signal isolation. This module ensures Keyphasor signals can be shared across multiple devices without interference or grounding issues, making it highly suitable for Magnetic Pickup applications.

Key Features

• Primary Use:
  • Provides isolation for Keyphasor signals, ensuring compatibility with multiple parallel systems, such as control systems.
  • Optimized for Magnetic Pickup applications but also supports Proximitor® applications (with an external power supply).
• Phase Measurements:
  • Capable of measuring phase but introduces slightly higher phase shift compared to the Non-Isolated I/O version.
• Primary Application: Shaft speed measurement rather than phase analysis.
