VM600 200-595-045-114 CPUM Mk2 Master Controller Card

1. Product Description

The 200-595-045-114 is the CPUM Mk2 main CPU communication card designed for Meggitt Vibro-Meter VM600 Mk2 modular machinery protection and condition monitoring system. It is a dual-slot VME board exclusively compatible with ABE040 / ABE042 6U 19-inch standard rack enclosures, paired with a matching IOCN Mk2 rear terminal card for external signal wiring.

• Integrated front-panel LCD display, status LED indicators and physical operation buttons for local on-site inspection and alarm reset.
• On-board USB and front RJ45 service port for local configuration via VibroSight software.
• 24 VDC backplane-powered, fully conformal coated PCB to resist dust, moisture and electromagnetic interference in industrial control cabinets.
• Equipped with hot-swap latches for online replacement without shutting down the whole rack in redundant system layout.

• Built-in QNX real-time operating system with 256MB local memory for waveform, FFT spectrum and millisecond-level SOE event storage.

2. Core Product Functions

• Rack Central Management: Poll measurement data from all installed MPC4 vibration protection cards, AMC8 analog acquisition cards and RLC16 relay output cards; perform unified three-level alarm logic (OK / Alert / Danger) judgment for machinery safety interlock.
• Multi-Protocol Communication Gateway: Provide isolated dual Modbus TCP Ethernet, Modbus RTU RS485 and Profinet IO interfaces through IOCN Mk2 terminal card, uploading vibration peak values, speed, temperature and fault status to plant DCS/PLC systems; support dedicated Meggitt protocol for VibroSight diagnostic workstation.
• Full System Self-Diagnosis: Continuously detect missing modules, sensor wire breakage, VME backplane communication failure, abnormal power supply and internal circuit degradation, and output fault alarms in real time.
• SOE & Condition Data Storage: Record time-stamped sequence of events for all abnormal trips and alarms; cache raw vibration waveforms and frequency spectrum data for post-fault analysis of unbalance, misalignment and oil whirl faults.
• Local Human-Machine Interaction: Front LCD screen supports real-time viewing of channel vibration displacement, rotational speed, alarm threshold parameters and module fault codes without external configuration computers.

3. Typical Application Scenarios

• Thermal power plant steam turbine-generator units, combined cycle gas turbine units, cooperating with BHEL UN series AVR excitation control cards for independent mechanical protection and generator voltage regulation.
• Large hydroelectric generating sets for shaft vibration, thrust displacement and overspeed monitoring protection.
• Petrochemical, steel and mining heavy-duty equipment: large air compressors, axial compressors and industrial blowers.
• Onshore & offshore captive power generation units and auxiliary rotating machinery monitoring cubicles.
