Bently Nevada 125800-01 Keyphasor I/O Module | Non-Isolated Internal Termination

Description

1. Product Overview

The Bently Nevada 125800-01 is a Keyphasor I/O Module designed for use with the 3500/25 Enhanced Keyphasor Module within the 3500 Series Machinery Protection System. This specific I/O module features Internal Terminations and is Non-Isolated, providing the physical interface to connect Keyphasor transducers (such as proximity probes) to the 3500 rack.

Installed in the rear of the 3500 rack, the 125800-01 ensures that the raw signals from the sensors are accurately transmitted to the main 3500/25 monitor for processing. It is an essential component for any system requiring stable phase reference and machine speed data.

Key Applications:

• Signal Interfacing: Connects proximity probes or magnetic pickups to the 3500/25 monitor.
• Machinery Protection: Part of the infrastructure for vibration analysis and speed monitoring.
• Rack Integration: Standard I/O interface for both half-rack and full-rack Bently Nevada 3500 configurations.

7. FAQ

Q: What is the difference between 125800-01 and 126006-01?

The 125800-01 is the Non-Isolated version, typically used in standard industrial environments. The 126006-01 is the Isolated version, which is required if your application needs galvanic isolation to prevent ground loops or protect against high-voltage surges between the field sensors and the rack.

Q: Can this I/O module be used with any 3500 monitor?

No, the 125800-01 is specifically designed for the 3500/25 Keyphasor Module. Other monitors like the 3500/42M or 3500/32 use their own specific I/O modules.

Q: Is the terminal block included with the module?

Yes, our brand-new 125800-01 modules come complete with the necessary terminal blocks for wiring. We ensure the package is ready for immediate installation upon arrival.
