Description
The part number MPC4200-510-SSS-1Hh corresponds to an advanced machinery protection card and processor module from the Meggitt Vibro-Meter VM600 series (often marketed under Meggitt Sensing Systems). The MPC4 card serves as the core processing and signal-conditioning hub within a VM600 Machinery Protection System (MPS), engineered for continuous vibration monitoring, shaft position analysis, and critical asset protection on large rotating machinery such as industrial gas turbines, steam turbines, compressors, and pumps.

Field Integration and Operational Notes
When installing or replacing an MPC4 card within a VM600 rack enclosure, ensure that the corresponding IOC4T input/output card matches the system configuration and field wiring terminations at the rear of the rack.
- Firmware and Software: The configuration parameters—including scaling factors, transducer types (e.g., eddy current proximity probes or piezoelectric accelerometers), alarm thresholds, and trip multipliers—must match the setup defined in the VM600 MPS software (such as VibroSight or legacy configuration tools) before placing the loop back online.
- Hot-Swapping: While the VM600 backplane supports modular design, always verify system trip logic bypass states in your Distributed Control System (DCS) or Emergency Shutdown System (ESD) before withdrawing or inserting modules to prevent spurious machine trips.
Frequently Asked Questions
Q: What is the primary function of the MPC4 card in a VM600 rack?
A: The MPC4 card acquires, filters, and processes raw signals from vibration and speed sensors, evaluates real-time alarm/trip criteria locally, and drives front-panel status indications as well as relay outputs via companion processing cards.
Q: Can the MPC4 card operate as a standalone unit without an IOC4T card?
A: No. The MPC4 machinery protection card functions in tandem with an IOC4T (Input/Output Card with Tachometer interface) housed in the rear of the VM600 rack, which physically terminates field wiring and routes signals to the processor.
Q: How are configuration settings modified on this module?
A: Configuration files are downloaded to the card using Meggitt’s dedicated software suites via the rack’s communication interface or front panel maintenance ports.
