Description

The Bently Nevada 125800-01 is a Keyphasor I/O module with internal terminations. The Bently Nevada 125800-01 provides the interface between Keyphasor transducers and the 3500/25 Enhanced Keyphasor Module. The Bently Nevada 125800-01 receives input signals from proximity probes or magnetic pickups and routes these signals to the monitor module for conversion to digital Keyphasor signals.

The Bently Nevada 125800-01 is a non-isolated I/O module. The Bently Nevada 125800-01 is used in applications where Keyphasor signals do not require isolation from control systems or other parallel-connected devices. The Bently Nevada 125800-01 provides a direct electrical path from the transducer to the monitor. The Bently Nevada 125800-01 is suitable for standard shaft speed and phase measurement applications.

Overview Manuals User guide Product Applications Physical Installation

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 125800-01 Bently Nevada Keyphasor I/O Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

The primary role of the 125800-01 is to receive raw pulses from Keyphasor transducers—usually proximity probes or magnetic pickups—which monitor a "once-per-turn" mark on a rotating shaft. These signals are critical for vibration analysis, as they provide the timing reference (phase) needed to filter vibration data to a specific frequency (1X, 2X, etc.) and to calculate accurate RPM. The module provides highly reliable screw-terminal connections, ensuring that these high-speed pulses are transmitted to the system backplane without degradation or noise interference.

Conveyor Systems:Prevents jerks/jolts damaging belts or products during startup
Turbines:Monitors bearings & stator windings to prevent overheating
Pumps & Motors:Focuses on winding & bearing housing temperatures
Gearboxes:Detects lubrication failure or internal friction
Other Industrial Equipment:Fans, blowers, extruders & pelletizers: continuous protection

This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.

Safety First: Ensure the 3500 rack power is turned OFF or that you are working in a certified safe, non-hazardous area.

Align and Slide: Align the I/O module with the top and bottom guides of the rear rack slot.

Seat the Module: Firmly slide the module into the slot until the rear connector fully mates with the rack’s backplane.

Technical notes

The Bently Nevada 125800-01 includes buffered transducer outputs. The Bently Nevada 125800-01 provides separate buffered outputs for each channel. These outputs allow connection of portable test equipment or diagnostic instruments without interrupting the signal path to the 3500 monitoring system. The Bently Nevada 125800-01 has front-mounted coaxial connectors for direct transducer connection.
