Bently Nevada 138607-01 Keyphasor I/O Module | 3500/25 Internal Terminations

Description

1. Product Overview

The Bently Nevada 138607-01 is a 2-channel Keyphasor I/O Module designed for the 3500/25 Enhanced Keyphasor system. This module features Internal Terminations, allowing field sensor wires from proximity probes or magnetic pickups to be connected directly to the terminal blocks on the rear of the 3500 rack.

The Keyphasor signal is a once-per-turn or multiple-event-per-turn pulse from a rotating shaft, which is essential for providing a phase reference and speed measurement. The 138607-01 acts as the physical interface that conditions these pulses, enabling the 3500 system to perform advanced diagnostics such as vector monitoring, orbit analysis, and synchronous sampling.

Key Applications:

• Phase Reference: Provides the timing pulse needed to calculate vibration phase angles.
• Speed Measurement: Continuously monitors shaft RPM for overspeed or underspeed protection.
• Transient Analysis: Vital for capturing data during machine startup and coast-down (Bode and Polar plots).
• Synchronous Monitoring: Allows the system to filter vibration data to the exact running speed of the machine.

7. FAQ

Q: What is the difference between 138607-01 and 125800-01?

The 138607-01 is the Enhanced Keyphasor I/O module designed for the 3500/25, whereas the 125800-01 is the older version for the standard 3500/25. While they look similar, the 138607-01 offers better signal processing and is required for newer system configurations.

Q: Can this module receive signals from a magnetic pickup?

Yes, the 138607-01 is designed to accept signals from both Proximitor probes (active) and magnetic pickups (passive). The sensor type is defined during the software configuration of the 3500/25 module.

Q: Is the terminal block included?

Yes, our brand-new 138607-01 units come with the original orange/green Euro-style terminal connectors included in the factory box.
