Bently Nevada 128718-01 3500 Series Internal Termination I/O Module

Product Overview

The Bently Nevada 128718-01 functions as a high-performance Internal Termination I/O Module specifically engineered for the 3500 Machinery Protection System. It facilitates the essential interface between the monitor modules and external transducers. By providing secure signal paths for vibration, position, or speed inputs, this module ensures the backplane receives clean, uncompromised data for real-time diagnostics. We offer this unit as 100% Brand New, original equipment to guarantee peak system integrity.

Technical Specifications

Engineering Advantages

• Noise Mitigation: The 128718-01 utilizes advanced filtering circuitry to suppress electromagnetic interference (EMI). This prevents high-frequency noise from corrupting low-voltage transducer signals in electrically noisy industrial environments.

• Direct Backplane Integration: The module snaps directly into the rear of the 3500 rack. This internal termination design eliminates the need for external terminal blocks, reducing the footprint within the control cabinet and simplifying cable management.

• High-Density Wiring Compatibility: The terminal headers accommodate a wide range of wire gauges. Even in cramped enclosures, the layout allows technicians to terminate shielded twisted-pair cables efficiently without straining the connectors.

• Thermal Resilience: Bently Nevada constructs this module using industrial-grade polymers and alloys. It maintains signal accuracy even when cabinet temperatures fluctuate, preventing "drift" in critical machinery protection data.

FAQs

• Can the 128718-01 replace an External Termination (ET) I/O module?

  No. This module features internal termination headers. If your system currently uses external terminal blocks and mass-termination cables, you must match the existing I/O architecture. The 128718-01 is specifically for direct-to-module wiring.

• What tools do I need for installation?

  A standard flat-head or Phillips screwdriver secures the field wiring to the terminal headers. The module itself slides into the rack guides and secures via two captive screws, requiring no specialized hardware.

• Does this module support hot-swapping?

  Yes, you can install the I/O module while the rack is powered; however, machinery protection will be lost for that specific channel during the swap. Always follow plant safety protocols before disconnecting transducer signals.

• How do I verify this is a 100% Brand New unit?

  Each unit arrives in original factory packaging with a verified serial number and date code, ensuring you receive genuine Bently Nevada hardware rather than refurbished or third-party alternatives.
