Description

The Bently Nevada 133434-01 is a Tachometer I/O Module designed for the 3500 series machinery protection system. This module serves as the interface for speed and phase monitoring, providing critical data for turbines, compressors, and other high-speed rotating equipment. It is engineered to process inputs from proximity probes or magnetic pickups, delivering precise speed measurements and phase reference signals to the 3500 rack system for overspeed protection and diagnostic analysis.

Features

• Dual-channel input capability for redundant or independent speed monitoring.
• Seamless integration with the Bently Nevada 3500 rack architecture.
• Supports both magnetic pickup and proximity probe sensor inputs.
• Provides essential phase reference signals for machinery diagnostics.
• Internal self-diagnostics to ensure system integrity and reliability.

Technical Specifications

Installation Guidelines

• Ensure the 3500 rack is powered down before inserting or removing the I/O module.
• Use appropriate ESD protection when handling the module to prevent damage to sensitive internal components.
• Verify that the I/O module is firmly seated in the rack slot and that the rear connectors are properly aligned.
• Route signal cables away from high-voltage lines or high-EMI sources to maintain signal integrity.
• Ensure all field wiring is properly shielded and grounded according to Bently Nevada installation standards for the 3500 series.

FAQ
