VIBRO-METER VM600 ABE040 System Rack (204-040-100-012): Overview and Technical Specifications
Brand and Model Identification
The 204-040-100-012 is a VM600 ABE040 system rack manufactured by Meggitt’s Vibro-Meter product line, designed as a robust housing and electrical backbone for VM600 series machinery protection and condition monitoring systems. This system rack serves as the foundation for configuring complete monitoring solutions in industrial environments, providing physical mounting space and electrical interconnections for all VM600 processing, input/output, relay, and controller modules.
Product Overview
The VM600 ABE040 system rack (204-040-100-012) is a 19-inch, 6U-height modular rack system specifically engineered to house up to 15 single-width VM600 modules (card pairs) or a combination of single-width and multiple-width modules. It features an integrated VME backplane that provides power distribution, signal processing connections, and communication buses between all installed modules, including the proprietary VM600 Tacho, Raw, and Open Collector (OC) buses. The rack supports both single and dual RPS6U power supply configurations for redundancy or extended environmental operation, making it suitable for critical machinery protection applications in power generation, oil & gas, and other heavy industries.

Technical Specifications
Physical Dimensions and Weight
The ABE040 system rack has a standard 19-inch (482.6 mm) width and 6U height (262 mm, 10.3 inches), with a depth of approximately 450 mm (17.7 inches) to accommodate front and rear module installation. The rack features an extruded aluminum frame and solid aluminum structural parts for durability, with top and bottom plastic guide strips for easy module insertion. The approximate weight of the empty rack is 8-10 kg (17.6-22 lb), depending on configuration options.
Key Features and Functional Characteristics
The 204-040-100-012 system rack offers several essential features including robust aluminum construction for industrial durability, modular slot configuration supporting flexible system design, and integrated backplane with VME and VM600-specific buses for seamless module communication. It includes a power supply check relay at the rear to indicate normal operation of installed RPS6U power supplies, and supports cabinet or panel mounting with front-positioned mounting brackets (differentiating it from the ABE042 model with rear brackets). The rack complies with IEC/EN 61000-6-2 and IEC/EN 61000-6-4 EMC standards and IEC 61010-1 safety standards, ensuring reliable operation in harsh industrial environments.
Power Requirements and Environmental Specifications
The system rack is designed for use with VM600 RPS6U power supplies that provide +5 VDC and ±12 VDC to all installed modules. A single 330 W RPS6U power supply supports a full rack of modules at operating temperatures up to 50°C (122°F), while dual power supplies can be installed for redundancy or to extend operation to wider environmental ranges. The rack operates in a temperature range of -25 to 70°C (-13 to 158°F) and can tolerate humidity levels from 0 to 90% relative humidity, non-condensing.
Slot Configuration and Module Compatibility
The front of the rack features 12 slots for processing modules (positions 03-14) such as MPC4, XMx16, and AMC8; 2 slots for rack controller modules (positions 00-01) including CPUMMk2 or CPUx; and 1 reserved slot for application-specific modules (position 02). The rear of the rack provides up to 19 slots for input/output modules (positions 00-18) such as IOC4T, XIO16T, and IOC8T, plus up to 4 slots for power supply rear panels (positions 17-20). All VM600 processing modules must be paired with their corresponding input/output modules, which are installed in the rear of the rack and provide connectors for sensor connections and external system integration.

Input Interfaces
The system rack receives power inputs from one or two RPS6U power supplies via dedicated rear panel connectors, which typically include AC and/or DC inputs with RFI filters, on/off switches, and fuses. The backplane provides electrical interconnections for all module inputs, including sensor signals from vibration, proximity, and temperature sensors, as well as communication inputs from external systems via the CPUM/IOCN controller modules.
Output Interfaces and Communication Protocols
The rear input/output modules provide various output interfaces including analog current/voltage outputs, digital relay outputs, and serial/Ethernet communication ports for integration with DCS, PLC, or monitoring software systems. The integrated VME backplane enables communication between CPUx modules and processing modules, while the VM600-specific buses facilitate data sharing between modules for synchronized monitoring and protection functions. The power supply check relay at the rear provides a dry contact output to indicate overall rack power status.
Application Compatibility
The 204-040-100-012 ABE040 system rack is fully compatible with all VM600Mk2/VM600 modules, supporting machinery protection, condition monitoring, and combustion monitoring applications. It can be configured using Meggitt’s VM600 MPSx or VibroSight software packages to meet specific machinery monitoring requirements, and is designed for permanent installation in 19-inch industrial cabinets or panels for long-term reliability.
