CMC16 Vibration 200-530-025-014 Condition Monitoring Card

Description:

The CMC16 Condition Monitoring Card is the central element in Vibro-Meter’s VM 600 series Condition
Monitoring System (CMS).
This intelligent front-end Data Acquisition Unit (DAU) is used in conjunction with the VM 600 CMS software to
acquire, analyse and transmit results to a host computer via the VM 600 series CPU M module with Ethernet
controller or directly via serial links.
The inputs are fully programmable and can accept signals representing speed, phase reference, vibration
(acceleration, velocity or displacement), dynamic pressure, airgap rotor and pole profile, any dynamic signals or
any quasi-static signals. Signals can be input from adjacent Machinery Protection Cards (MPC 4) via the VM 600
‘Raw Bus’ and ‘Tacho Bus’ or externally via the screw terminal connectors on the IOC 16T. The IOC 16T modules
also afford signal conditioning and EMC protection and allow inputs to be routed to the CMC 16, which includes 16
programmable tracked anti-aliasing filters, and Analogue-to-Digital Converters (ADC). On-board processors
handle all control of acquisition, conversion from time domain to frequency domain (Fast Fourier Transform), band
extraction, unit conversion, limit checking, and communication with the host system.

Features:

• 16 individually configurable dynamic channels
• 16 parallel programmable anti-aliasing filters and ADCs
• First 4 channels also configurable as tacho inputs
• Last 12 channels also configurable as process values
• VME architecture
• Configurable Synchronous and Asynchronous sampling
• High resolution 3200- line FFT
• 10 fully configurable frequency bands per channel
• 6 configurable alarms per band with hysteresis deadbands
• Schedule, ‘on-alarm’ and ‘on exception’ based logging
• Ethernet and Serial RS-485 communication options
• On-board buffer storage
• Status indication by 3-colour LED on front panel
• Live insertion / removal of cards with automatic configuration

Frequently Asked Questions:
1.What are the A/D converter parameters?
1 converter per channel, 14 bits
Values transmitted to PC are truncated to 12 bits + sign
(resolution 1 in 4096)

2.What is input voltage range of CMC16?
1 to 24 V pulse (AC coupled in the -24 V / +24 V range)
