The MPC4 machinery protection card is the central element in the VM600 series machinery protection system (MPS), from Meggitt’s Vibro-Meter® product line. This very versatile card is capable of measuring and monitoring up to four dynamic signal inputs and up to two speed inputs simultaneously.
The dynamic signal inputs are fully programmable and can accept signals representing acceleration, velocity and displacement (proximity), among others. On-board multichannel processing allows measurement of various physical parameters, including relative and absolute vibration, Smax, eccentricity, thrust position, absolute and differential housing expansion, displacement and dynamic pressure.
Digital processing includes digital filtering, integration or differentiation (if required),rectification (RMS, mean value, true peak or truepeak-to-peak), order tracking (amplitude and phase) and measurement of the sensor-target gap.
Key Features and Benefits：
1.The MPC4SIL (200-510-071-113) card lacks a VME-compatible slave interface, does not support tachometer (speed) channels, and does not provide the full range of signal processing capabilities offered by the standard MPC4 card (for details, see the specifications on page 9 regarding the standard and separate circuits MPC4 cards).
2.The VM600 rack, including machinery protection cards, condition monitoring cards, and the associated software, is designed to comply with the segregation requirements of the API 670 standard. This ensures that the functionality of the Machinery Protection System (MPS) is independent and unaffected by the operation of the Condition Monitoring System (CMS).
3.While machinery protection and condition monitoring cards can share sensor signals, MPC4/IOC4T card pairs do not share communication buses with XMx16/XIO16T card pairs within the VM600 rack. Additionally, the configuration and operation of MPC4/IOC4T card pairs are managed via the VM600 MPSx software, whereas the XMx16/XIO16T card pairs are configured and operated through VibroSight software.
