Bently nevada Enhanced Keyphasor Module 3500/25 125800-01
|
|
3500/25 125800-01 Types
|
The 3500/25 Enhanced Keyphasor Module is a half-height, two-channel module 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.

Specifications:
Inputs
Power Consumption:3.2 Watts typical
Signal:Each Keyphasor Module accepts up to two
transducer signals from proximity probe transducers or magnetic pickups. The input signal range is +0.8 V
to -21.0 V (NonIsolated I/O modules) or +5V to -11V
(Isolated I/O modules). Signals exceeding this range are limited internally by the module. Passive magnetic pickups require a shaft rotative speed greater than 200 rpm (3.3 Hz).
Input Impedance: 21.8 kΩ minimum
Outputs
Buffered Keyphasor Signals:Two buffered Keyphasor
outputs are available at the front of the rack via coaxial
connectors. Two buffered Keyphasor outputs are also
available at the back of the rack via Euro Style connectors.
Output Impedance：504 Ω maximum buffered output impedance.
Keyphasor Transducer Power Supply：-24 Vdc, 40 mA maximum per channel.
Description:
The Enhanced Keyphasor Module is an improved 3500 system module. It offers expanded Keyphasor signal processing capabilities over the previous design while maintaining complete downward-compatibility in terms of form, fit and function with existing Keyphasor modules for use in legacy systems. The Keyphasor module, PWA 125792-01, is completely replaced by the updated 149369-01 module.
When a system Keyphasor input is required for Triple Modular Redundant (TMR) applications, the 3500 system should employ two Keyphasor modules. In this configuration, the modules work in parallel to provide both a primary and secondary Keyphasor signal to the other modules in the rack.
