3500/25 149369-01 | Bently Nevada | Enhanced Keyphasor Module

Description

Features: • Half-height • (2) Channels • Input Signals: Proximity Probes or Magnetic Pickups The/ Bently Nevada 3500/25 Series Enhanced Keyphasor Modules are half-height, two-channel modules 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.

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.

A system with more than four Keyphasor inputsmay usea paired configuration provided thereare no more than four primary Keyphasor inputsignals. A paired configuration requires twoconsecutive monitoring positions in either theupper/lower or both half-slot positions.  FourKeyphasor modules will accept four primaryand four backup input channels and providefour output channels (one per module). Aconfiguration of two paired and one nonpaired (three Keyphasor modules total) is alsopossible.  In sucha configuration, the user mayconfigure the one non-paired Keyphasor(order either two 2-channel or one 1-channeland one 2-channel option) The Isolated Keyphasor I/O module is designedfor applications where the Keyphasor signalsare tied in parallel to multiple devices andrequire isolation from other systems, such asacontrol system.  The Isolated I/O module wascreated specifically for Magnetic Pickupapplications but is compatible with and willprovide isolation for Proximitor* applications aslong as an external power supply is provided. The intent of this I/O module was primarily tomeasure shaft speed and not phase. Themodule can provide phase measurements, butthis I/O introducesa slightly higher phase shiftthan the Non-Isolated I/O version. Figure1shows the amount of phase shift that theIsolated I/O modules will add at differentmachine speeds. Enhanced product features include generationof once-per-turn event signals from multievent-per-turn inputs, field-upgradeablefirmware, and asset management datareporting.
