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.
• Ensure the module is fully seated in the rack slot and the front panel screws are tightened to maintain proper grounding and EMI shielding.
• Route signal cables away from high-voltage or high-EMI sources to maintain signal integrity for proximity probes and magnetic pickups.
• Verify that the external termination block is correctly wired according to the system documentation before applying power.

FAQ

What is the primary function of the 3500/50 133450-01?

The 133450-01 is an I/O module for the 3500 system that processes speed and phase signals, providing the necessary data for overspeed protection and machinery diagnostics.

Is this module compatible with all 3500 racks?

Yes, it is designed for use within the standard Bently Nevada 3500 series rack environment, specifically supporting TMR configurations.

What does the TMR designation mean?

TMR stands for Triple Modular Redundant. This design uses three parallel circuits to process inputs and a voting mechanism to ensure that the system remains operational and accurate even if a single component fails.
