Bently Nevada 3500/25 Enhanced Keyphasor Module

Description

The 3500/25 Enhanced Keyphasor Module is a half-height,two-channel module used to provide Keyphasor signals tothe monitor modules in a 3500 rack. The module receivesinput signals from proximity probes or magnetic pickups andconverts the signals to digital Keyphasor signals that indicatewhen the Keyphasor mark on the shaft coincides with theKeyphasor transducer. The 3500 Machinery ProtectionSystem can accept up to four Keyphasor signals for normalconfiguration and up to eight Keyphasor signals in a pairedconfiguration.
The Enhanced Keyphasor Module is an improved 3500system module. It offers expanded Keyphasor signalprocessing capabilities over the previous design whilemaintaining complete downward-compatibility in terms ofform, fit and function with existing Keyphasor modules for usein legacy systems. The Keyphasor module, PWA 125792-01, iscompletely replaced by the updated 149369-01 module.When a system Keyphasor input is required for Triple ModularRedundant (TMR) applications, the 3500 system shouldemploy two Keyphasor modules. In this configuration, themodules work in parallel to provide both a primary andsecondary Keyphasor signal to the other modules in the rack.
