Overview of 3500/25 Enhanced Keyphasor Module

The 3500/25 Enhanced Keyphasor Module is a compact, half-height, two-channel module designed to provide precise Keyphasor signals to the monitor modules in a 3500 rack.

• Input signals sourced from proximity probes or magnetic pickups.
• Conversion of input signals to digital Keyphasor signals, marking when the Keyphasor mark on the shaft aligns with the Keyphasor transducer.
• Capability to support up to:
  • Four Keyphasor signals in standard configuration.
  • Eight Keyphasor signals in paired configuration.

The module is an integral part of the 3500 Machinery Protection System, enhancing its ability to monitor and protect rotating equipment.
