200-530-025-014 | Vibro-Meter | VM 600 | CMC 16 | Condition Monitoring Card

The 200-530-025-014 CMC 16 Condition Monitoring Card is the core component of the Vibro-Meter VM 600 series CMS. It functions as an intelligent front-end Data Acquisition Unit (DAU) that collaborates with the VM 600 CMS software to gather, analyze, and transmit results to a host computer via the VM 600 series CPU M module with Ethernet controller or directly through serial links.

Key Features

• Fully programmable inputs for various signal types including:
  • Speed and phase reference
  • Vibration (acceleration, velocity, displacement)
  • Dynamic pressure and airgap rotor profiles
  • Any dynamic or quasi-static signals
• Signal input via:
  • Machinery Protection Cards (MPC 4) via the VM 600 ‘Raw Bus’ and ‘Tacho Bus’
  • Screw terminal connectors on the IOC 16T
• On-board signal conditioning, EMC protection, and extensive filtering capabilities (16 programmable anti-aliasing filters)
• Capable of high-resolution data acquisition and processing (waveforms, spectra, orbits)
• Supports adaptive monitoring techniques for dynamic alarm set points
• Provides various metrics (RMS, peak values) and configurable bands based on acquired spectra
• Transient Mode for higher density logging during events
