Vibro-Meter VMF-CPUM 200-595-046-114 CPU Module: Overview and Technical Specifications
Brand and Model Identification
The VMF-CPUM 200-595-046-114 is a Central Processing Unit (CPU) module manufactured by Meggitt Vibro-Meter (now part of Meggitt Sensing Systems), specifically designed for the VM600 series of machinery protection and condition monitoring systems. It serves as a critical rack controller and communication interface card that enables seamless integration between VM600 monitoring components and external industrial control systems.
General Specifications
This CPU module operates on a 24V DC power supply (standard for industrial automation systems) and features a robust construction suitable for harsh industrial environments. It supports live insertion and removal of modules within the VM600 rack, allowing for hot-swapping capabilities without system shutdown. The module has a typical weight of 0.17 kg (170g) and compact dimensions of 86mm x 100mm x 35mm (WxHxD), making it space-efficient for installation in crowded control cabinets.
Physical Dimensions and Weight
Dimensions: 86mm (width) × 100mm (height) × 35mm (depth)
Weight: 0.17 kg (170 grams)
Form Factor: VM600 rack-mountable module, compatible with standard VM600 series racks
Mounting: Card-edge connector for secure rack integration
Key Features
The VMF-CPUM 200-595-046-114 offers a comprehensive set of features for industrial machinery monitoring applications:
Acts as a rack controller for VM600 systems, managing communication between all installed monitoring cards (such as MPC4 machinery protection cards and AMC8 condition monitoring cards)
Functions as a communication gateway between VM600 and third-party systems including DCS, PLC, and SCADA systems
Provides “One-Shot” configuration management of protection cards via Ethernet or RS-232 serial connection to a computer running VM600 MPSx software
Features a front-panel display for visualizing monitored outputs and alarm limits from protection cards
Includes a front-panel alarm reset (AR) button for manual acknowledgment of system alarms
Supports VM600 MPS rack security features to prevent unauthorized access to critical protection settings
Enables sharing of measurement data from VM600 monitoring cards in machinery protection, condition monitoring, and combustion monitoring applications
Facilitates real-time processing of critical machinery data to support predictive maintenance strategies
Communication Interfaces and Protocols
The module supports multiple communication interfaces for versatile connectivity options:
Two Ethernet connections for high-speed data transfer and network communication
Up to three serial connections (RS-232 / RS-422 / RS-485) that can operate simultaneously
Supports industry-standard fieldbus protocols including Modbus RTU/TCP and PROFINET for seamless integration with industrial control systems
Communication redundancy with multiple fieldbuses to ensure continuous operation even if one communication path fails
