Description
Bently Nevada 126648-01
Keyphasor I/O Module | External Terminations | 3500 Machinery Protection System
Product Detailed Description
The Bently Nevada 126648-01 is a Keyphasor I/O module used with the 3500 Machinery Protection System and compatible Enhanced Keyphasor monitoring hardware. It provides an interface for shaft speed and phase-reference signals from supported sensors, helping monitoring equipment determine rotational speed and phase-related information for machinery diagnostics. This version uses external terminations, so the appropriate termination hardware and wiring configuration must be verified before installation.
