TheBently Nevada 126648-02is an Isolated Keyphasor I/O Module with External Terminations, designed for the 3500 Series Machinery Protection System. It is primarily engineered to interface with magnetic pickups to measure shaft rotative speed and vector parameters. This module is ideal for applications where Keyphasor signals must be connected in parallel to multiple devices while maintaining electrical isolation from other systems, such as control systems.
Compatibility:Specifically designed for magnetic pickups; compatible with Proximitor applications if an external power supply is utilized.
Signal Isolation:Provides high-level isolation for signals connected in parallel to multiple devices.
Features
Shaft Speed Measurement:Primary design focus is the accurate measurement of shaft rotative speed rather than just phase.
Digital Signal Conversion:Receives input from proximity probes or magnetic pickups and converts them into digital Keyphasor pulses (once or multiple times per turn).
Vector Parameter Tracking:Enables 3500 monitor modules and diagnostic equipment to measure 1X vibration amplitude and phase.
Flexible Input Sources:Capable of processing signals from both magnetic pickups and proximity transducers.
Phase Measurement Capability:While optimized for speed, it can provide phase measurements (noting a slightly higher phase shift than non-isolated versions).
Precise Timing:Delivers exact timing measurements essential for machinery diagnostic and protection functions.
