Bently Nevada 135473-01 3500/25 Keyphasor I/O Module

The Bently Nevada 135473-01 is a 3500/25 Keyphasor I/O Module with Internal Barriers and Internal Terminations used together with the 3500/25 Enhanced Keyphasor Module.

The Keyphasor system provides a once-per-turn or multi-event-per-turn reference signal from a rotating shaft. This reference signal allows the 3500 monitoring system to calculate:

• Shaft rotational speed

• Rotor phase angle

• 1X vibration phase reference

• Timing relationship between shaft position and vibration response

The 135473-01 receives signals from Keyphasor sensors and provides isolated signal routing between field devices and the 3500 rack system. It is especially suitable for installations where the Keyphasor signal must be shared with multiple devices while maintaining electrical separation.

The module supports applications using:

• Magnetic pickup sensors

• Proximity probe based Keyphasor systems

and works as part of a complete Bently Nevada 3500 machinery protection configuration.
