The Vibro-Meter MPC4 (part number 200-510-078-115) is a continuous, online machinery protection card manufactured by Meggitt / Vibro-Meter (Parker Meggitt). Operating as the primary signal processing unit within the VM600 Machinery Protection System (MPS), the MPC4 processes dynamic vibration, position, and speed inputs to protect critical industrial turbomachinery.
The 200-510-078-115 designation represents a specific production variant of the MPC4 card family, equipped with onboard conformal coating for harsh plant atmospheres and full compatibility with IOC4T rear input/output cards.

Core Features & System Capabilities
- 4 Dynamic + 2 Speed Channels: Simultaneously monitors up to four dynamic vibration sensors (shaft displacement, casing vibration) alongside two independent tachometers for phase angle and speed tracking.
- Real-Time DSP Processing: Onboard Digital Signal Processors compute real-time amplitude values (Peak, RMS) and filter bands to detect imbalance, misalignment, bearing wear, or blade pass frequencies.
- Integrated Alarm Logic & Trip Outputs: Evaluates Alert and Danger setpoints per channel with configurable time delays, routing trip signals across the rack backplane to relay modules (such as the RLC16).
- Front Panel Raw BNC Outputs: Features dedicated front-panel buffered BNC connectors for direct connection to portable FFT vibration analyzers during routine machinery diagnostics.
- Conformal Coating & Harsh Environment Build: The
-078-115hardware option includes protective conformal coating to prevent corrosion from airborne moisture and aggressive gases in chemical processing plants.
