The Vibro-Meter VM600 MPC4 (part number 200-510-071-113) is a high-density, 4-channel dynamic signal processing and machinery protection card manufactured by Meggitt / Vibro-Meter (now Parker Meggitt). Operating within the VM600 rack platform, the MPC4 provides real-time vibration monitoring, speed tracking, and automated emergency trip execution for critical rotating machinery such as gas/steam turbines, centrifugal compressors, boiler feed pumps, and hydro generators.

Core Features & System Capabilities
- Multi-Sensor Dynamic Inputs: Processes raw signals from eddy-current proximity probes (shaft vibration, axial displacement, keyphasor), piezoelectric accelerometers, velocity sensors, and dynamic pressure transducers.
- Integrated Speed & Phase Measurement: Features 2 independent tachometer channels to track shaft rotational speed, calculate speed-dependent alarm thresholds, and measure phase angles for order tracking.
- SIL 2 Safety Architecture: Fully certified to IEC 61508 SIL 2 standards for deployment in automated Emergency Shutdown Systems (ESD) and critical machinery trip loops.
- Real-Time DSP Signal Conditioning: Dual Digital Signal Processors (DSP) extract Peak, Peak-to-Peak, RMS, Smax, and GAP measurements in real time to detect unbalanced shafts, bearing wear, misalignment, and cavitation.
- Paired IOC4T Rear Card Integration: Interfaces with a rear-mounted IOC4T card over the VM600 backplane to provide field wiring screw terminals, raw signal BNC/buffered outputs, and 4–20 mA DC current loops.
