Each channel is compatible with all types of rotating machinery sensors, with onboard built-in sensor power supply:
Eddy Current Probe (Relative Vibration of Shaft, Thrust Shaft Displacement, Gap Voltage)
Piezoelectric Acceleration Sensor (Absolute Vibration of Shell)
Electromagnetic Speed Sensor
Supported Measurement Parameters: Peak-to-peak Shaft Vibration, Shell Vibration Velocity, Eccentricity Smax, Axial Thrust Displacement, Cylinder Expansion, Dynamic Pressure; Built-in Integration / Differentiation, Digital Filtering, Order Tracking (Amplitude + Phase), Gap Voltage Monitoring
2. Speed / Phase Channels (2 channels)
Compatible with Eddy Current Phase Probes, Magnetic Pulse Sensors, TTL Level; Supports fractional speed ratios, used for speed adaptive alarm, vibration order analysis, phase fault diagnosis
3. Panel Interface
Front 6 BNC Buffered Outputs: Can be externally connected to oscilloscopes to read raw sensor waveforms; 7 LED Status Lights (Operation, Fault, Channel Alarm, Hazard Shutdown, System Fault); Supports hot-swappable maintenance

Safety and Certification (Exclusive to 200-510-064-034)
SIL 2 Safety Integrity Level Certification (IEC 61508), the last digit of the order number 034 corresponds to the SIL safety version; The standard version has the last digit 014, which cannot be mixed in the unit isolation protection circuit
Whole Machine BIST Self-Test: Power-on / Real-time Channel Break, Sensor Short Circuit, Backplane Communication Failure Self-test, when a fault occurs, force all relays to be in a safe shutdown state
Complies with power plant explosion-proof EMC, CE, ATEX industrial standards, suitable for strong electromagnetic cabinet environments of gas turbines, steam turbine generator sets

Signal Output and Communication (Coordinated with IOC4T)
Alarm Relays: 4 programmable relays (Warning / Hazard Shutdown / Channel Fault / System Fault), can be directly connected to the unit ETS isolation system
Analog Output: 1 4-20mA per dynamic channel, upload to DCS/PLC to display real-time values of vibration and displacement
System Bus: Parallel bus inside the VM600 rack, multiple MPC4s share the backplane; Ethernet communication connects to VM600 MPSx upper-level software, supports fault recording, trend curve storage
Maximum Expansion: Up to 12 groups of MPC4 + IOC4T in one VM600 rack, totaling 48 dynamic vibration monitoring channels of Meggitt Sensing Systems

Electrical and Environmental Parameters
