135473-01 3500/25 | Bently Nevada | Enhanced Keyphasor I/O Module

Product Overview

The Bently Nevada 135473-01 serves as the primary Interface/Output (I/O) module for the 3500/25 Keyphasor system. This module accepts once-per-turn or multiple-pulse-per-turn signals from proximity probes or magnetic pickups. It converts these inputs into highly accurate digital phase and speed data, which the entire 3500 rack utilizes for synchronized vibration analysis. We supply this component as 100% Brand New and factory-original, ensuring your machinery protection system maintains sub-degree phase accuracy.

Technical Specifications

Engineering Advantages

• Precise Phase Reference: The 135473-01 provides the critical timing pulse needed to calculate phase angles. This allows engineers to identify machinery imbalances, misalignments, and shaft cracks with high diagnostic confidence.

• Internal Termination Efficiency: This specific version features internal terminations. Technicians wire field transducers directly to the module's terminal blocks, eliminating the need for external terminal strips and reducing cabinet wiring complexity.

• Extreme Environmental Resilience: The module operates within a massive temperature range (-40°C to +85°C). It survives the thermal stress of unconditioned turbine enclosures and extreme outdoor industrial sites without signal drift.

• EMI/RFI Hardening: Industrial environments generate massive electrical noise. Bently Nevada shields the 135473-01 against electromagnetic interference, preventing "double-triggering" or false speed readings that could disrupt plant operations.

FAQs

• Is the 135473-01 a "Half-Height" or "Full-Height" module?

  The 135473-01 is a half-height I/O module. It installs into the rear of the 3500 rack, specifically designed to match the half-height 3500/25 Keyphasor monitor card located in the front of the chassis.

• What type of sensors can I connect to this I/O module?

  It supports a wide range of transducers, including Bently Nevada 3300 XL proximity probes and magnetic pickups. You can configure each channel via the 3500 Rack Configuration Software to match the specific sensor's threshold and hysteresis requirements.

• Can I swap this module while the 3500 rack is powered?

  The 3500 system supports hot-swapping; however, removing the 135473-01 will cause all monitor cards relying on that Keyphasor signal to lose their phase reference. We recommend reviewing your system interlocks before performing live maintenance.

• How do I confirm this is 100% Brand New?

  Every 135473-01 we ship arrives in original Bently Nevada anti-static packaging with intact factory seals. Each unit includes a unique serial number that matches factory records, ensuring you receive genuine hardware, not a refurbished unit.
