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, thrus position, absolute and differential housing expansion, displacement and dynamic pressureDigital processing includes digital filtering,
integration or differentiation (if required), rectification (RMS, mean value, true peak or true
peak-to-peak), order tracking (amplitude and phase) and measurement of the sensor-target

The speed (tachometer) inputs accept signals
from a variety of speed sensors, including systems
based on proximity probes, magnetic pulse pick
up sensors or TTL signals. Fractional tachometer
ratios are also supported

trait
4 dynamic channels and 2 tachometer channels
Each dynamic channel has 2 processing outputs, each dual channel has 1 processing output (2 per MPC4), and each tachometer channel has 1 processing output
Highly configurable cards support all measurements required for mechanical protection applications, such as relative and/or absolute vibration
The highly integrated card pair (with IOC4T) includes a sensor power supply, buffer output, DC output, relay, and serial communication interface
Designed to work with VM600 MPSx software
