The Bently Nevada 149369-01 3500/25 Enhanced Keyphasor Module is a specialized device used in machinery monitoring systems to provide Keyphasor signals. Here’s a breakdown of its features, specifications, and ordering information:

Description:

  • The module receives input signals from proximity probes or magnetic pickups and converts them into digital Keyphasor signals.
  • Keyphasor signals indicate when a specific mark on a rotating shaft aligns with the Keyphasor transducer.
  • The system can accept up to four Keyphasor signals in a normal configuration and up to eight in a paired configuration.
  • Keyphasor signals are essential for precise timing measurements, including shaft rotational speed and vector parameters like 1X vibration amplitude and phase.

Enhancements:

  • The Enhanced Keyphasor Module improves upon the previous design with expanded signal processing capabilities.
  • It maintains backward compatibility with existing Keyphasor modules for legacy systems.
  • The older Keyphasor module (PWA 125792-01) is replaced by the newer 149369-01 module.

Configuration:

  • In Triple Modular Redundant (TMR) applications, two Keyphasor modules are used to provide primary and secondary Keyphasor signals.
  • Paired configurations are possible for systems with more than four Keyphasor inputs, allowing four primary and four backup input channels.

Isolated Keyphasor I/O Module:

  • Designed for Keyphasor signals tied in parallel to multiple devices and requiring isolation from other systems.
  • Suitable for Magnetic Pickup applications with the addition of an external power supply.
  • Note that this module primarily measures shaft speed, and it introduces a slightly higher phase shift compared to the non-isolated version.

Enhanced Product Features:

  • Offers the generation of once-per-turn event signals from multi-event-per-turn inputs.
  • Supports field-upgradeable firmware.
  • Provides asset management data reporting.

Specifications (Selected):

  • Power Consumption: 3.2 Watts typical.
  • Input Signal Range: +0.8 V to -21.0 V (Non-Isolated I/O modules) or +5V to -11V (Isolated I/O modules).
  • Input Impedance: 21.8 kΩ minimum.
  • Input Range: 1 to 1,200,000 cpm (0.017 to 20 kHz).
  • Output Range: 1 to 99,999 cpm (0.017 to 1667 Hz).
  • Output Impedance: 504 Ω maximum buffered output impedance.
  • Keyphasor Transducer Power Supply: -24 Vdc, 40 mA maximum per channel.
  • Operating Temperature: -30°C to +65°C (-22°F to +150°F).

Environmental Limits:

  • Operating Temperature ranges depending on the use of Internal Barrier I/O Module or Keyphasor I/O Module.

Compliance and Certifications:

  • Complies with EMC standards and electrical safety standards.
  • Certified for hazardous area use.

Physical Dimensions (Main Module):

  • Height x Width x Depth: 119.9 mm x 24.4 mm x 256.5 mm.
  • Weight: 0.34 kg (0.76 lbs.).

Rack Space Requirement:

  • Main Module: 1 half-height front slot.
  • I/O Modules: 1 full-height rear slot.

Ordering Considerations:

  • Different options are available based on the number of channels, type of I/O module, and agency approval requirements.
  • External Termination Blocks and Cables may need to be ordered separately.
  • Consult with a qualified Bently Nevada sales representative for complex applications.
