MPC4 200-510-071-113
Mechanical Protection Card
The MPC4 200-510-071-113 is a mechanical protection card and a core component of the Mechanical Protection System (MPS). This card can process up to four dynamic signal inputs and two speed inputs simultaneously. The dynamic signal inputs of the MPC4 card are fully programmable, allowing it to receive various types of signals representing acceleration, velocity, and displacement (eddy current), among others.
The onboard multi-channel processing functionality enables precise measurement of a range of physical parameters, including:Relative and absolute vibration/Smax (maximum shaft vibration)/Eccentricity/Thrust position/Absolute and differential casing expansion/Displacement and dynamic pressure.
Safety Certification and Multiple Version Options
The MPC4 200-510-071-113 card is available in three versions: "Standard", "Independent Circuit", and "Safety" (SIL) versions. All versions must be paired with the corresponding IOC4T input/output card for proper operation. Some versions also offer a conformal coating on the circuit board, providing additional environmental protection against chemicals, dust, moisture, and extreme temperatures.
The "Standard" and "Safety" (SIL) versions of the MPC4 card are certified according to IEC 61508 and ISO 13849, ensuring compliance with international safety standards.
Output Functionality
The MPC4 200-510-071-113 card provides digital outputs for each alarm level, which can be accessed through the corresponding IOC4T input/output card. These alarm signals can drive the four local relays on the IOC4T card or be routed via the Raw Bus or Open Collector (OC) main line of the VM600 rack to optional relay cards (such as RLC16 or IRC4) for further control.
Additionally, the processed dynamic (vibration) signals and speed signals are available as analog output signals at the rear of the rack (IOC4T front panel). These outputs include both voltage-based signals (0 to 10 V) and current-based signals.
Technical Specifications Overview

Application Fields and Market Value
The MPC4 200-510-071-113 is used in power generation, petrochemical, and compressor stations for gas turbines, steam turbines, centrifugal compressors, and pump sets. Its core value lies in its "dual role": it functions both as a hard-wired protection device that meets API 670 standards (capable of directly triggering trip relays) and as a data source for Condition Monitoring Systems (CMS) (by uploading data to a higher-level system via Modbus/TCP or OPC).
In retrofit projects for aging units, the MPC4 card is also commonly used to upgrade analog instrumentation to a digital protection system. With just 1–2 cards, it can replace dozens of mechanical vibration meters and relays.
