Bently Nevada 149369-01 3500/25 Enhanced Keyphasor Module

This model is used to provide Keyphasor signals to the monitor modules in a 3500 rack. The
module receives input signals from proximity probes or magnetic pickups and
converts the signals to digital Keyphasor signals that indicate when the
Keyphasor mark on the shaft coincides with the Keyphasor transducer. The 3500
Machinery Protection System can accept up to four Keyphasor signals for
normal configuration and up to eight Keyphasor signals in a paired
configuration.
