Product Details
The 3500/25-02-01-05 Enhanced Keyphasor Module is a half-height, two-channel module designed for the Bently Nevada 3500 Series Machinery Protection System. It acquires input signals from proximity transducers or magnetic pickups to provide precise rotational speed, phase angle, and vector measurements for rotating machinery. This specific configuration features an I/O module with external terminations, internal barriers, and agency approvals for hazardous locations.
Signal Processing and Phase Reference
The module processes shaft-mounted keyway or notch target waveforms to generate digital timing pulses utilized across the 3500 framework. These Keyphasor pulses enable synchronous sampling, precise vibration vector calculations, and advanced phase analysis for machinery protection monitors. Each independent channel conditions incoming signals to reject electrical noise and maintain stable speed tracking through transient and steady-state operations.
Hardware Configuration and I/O Interface
Occupying two front slots within a standard 3500 rack, the assembly pairs the main processor board with a designated rear I/O module. The -02 designation indicates an I/O module option configured with external terminations, routing field wiring through separate termination blocks. The -01 and -05 suffixes denote internal barrier provisions and multi-agency certifications for hazardous areas. Front-panel LED indicators provide real-time status for channel operation, transducer power supply health, and module readiness.
