3. Hardware Structure & Design Details

3.1 Overall Structural Design

Adopting a modular and standardized frame design, the device features a 19-inch 6U standard rack structure made of high-strength aluminum alloy, balancing structural rigidity and lightweight design. It effectively resists vibration, shock and dust erosion in industrial environments, meeting the requirements of long-term continuous operation. The rack is divided into front panel, rear panel and internal backplane with clear functional zoning for easy installation, maintenance and expansion.

The core structure consists of rack enclosure, VME backplane bus, slot mounting mechanism, power installation area, relay alarm interface and cable interface. All components are designed per industrial standards to ensure stable electrical connection and reliable equipment operation.

3.2 Key Component Design

3.2.1 Rack Enclosure & Material

The enclosure is made of corrosion-resistant high-strength aluminum alloy with special surface treatment to prevent oxidation and corrosion. Complying strictly with 19-inch industrial standard and 6U height, it fits standard industrial cabinets and panel mounting. The 300mm depth structure meets installation requirements of various functional modules and reserves sufficient heat dissipation space to guarantee long-term stable operation of modules.

3.2.2 VME Backplane Bus

The built-in VME backplane bus acts as the core of electrical interconnection for all functional modules, responsible for power distribution, signal transmission and data interaction to coordinate the operation of power modules, CPU modules, monitoring modules and I/O modules.The backplane supports 64 RAW-BUS channels covering all slots, 8 Tacho-BUS channels covering slots 3–14, and 6 groups of OC-BUS (2 slots per group, 16 channels per group). It ensures high-efficiency and stable signal transmission with electrical isolation between all modules to avoid interference.

3.2.3 Slot & Mounting Mechanism

The rack is configured with 15 standardized slots compatible with all single-slot and dual-slot functional cards of the VM600 series. Precision positioning and locking structures inside slots ensure firm module installation and prevent looseness or poor contact caused by industrial vibration.Slots 15–20 are dedicated for power modules (1–2 RPS6U modules installable); Slots 0/1 are exclusive for CPU-M; Slots 3–14 accommodate MPC4 and other monitoring & processing modules; Rear Slots 1/2/15~18 are for RLC16, IRC4 and other relay modules. The rational layout facilitates classified installation and maintenance.

3.2.4 Power & Alarm Interface

Power input interface and power check relay interface are arranged at the rear of the rack. The power interface adapts AC/DC input of RPS6U modules (90~264VAC, 9.2~28.8VDC and other specifications) and supports redundant power access. The power check relay monitors real-time power status and outputs alarm signals via the rear interface upon power failure for timely troubleshooting.

3.2.5 Heat Dissipation & Protection Design

Reasonable heat dissipation channels are reserved inside the rack. Combined with the heat dissipation structure of functional modules, it adopts natural cooling plus forced cooling to ensure stable operation within -20℃~+70℃ working temperature. The sealed enclosure effectively blocks dust and moisture ingress. Conformal coatings are applied to power circuits to further enhance resistance to chemical substances and extreme temperatures and extend service life.

4. Working Principle

As the core rack of the VM600 vibration monitoring system, the Vibro-meter VM600-ABE042 204-042-100-011 provides a stable hardware mounting carrier, electrical interconnection channel and power distribution for the entire system. It coordinates collaborative operation of all functional modules to realize collection, processing, analysis and early warning of vibration signals from industrial rotating machinery.

Specific Working Process

Power Supply Distribution: The externally input AC/DC power is converted into 5V and ±12V system power via RPS6U modules installed on the rack, then distributed to each functional module through the VME backplane bus to provide stable power supply. Redundant power configuration ensures continuous system operation and avoids monitoring interruption when one power supply fails.
Module Coordination: The VME backplane bus realizes electrical connection and data interaction among CPU modules, monitoring modules (MPC4/CMC16), I/O modules and relay modules. As the system core, the CPU module undertakes configuration, data processing and communication control. Monitoring modules collect and pre-process vibration sensor signals via I/O modules; processed data is transmitted to the CPU module for further analysis and storage, then uploaded to the industrial control system through communication interfaces.
Condition Monitoring & Alarm: The power check relay monitors the running status of power modules in real time and outputs alarm signals via the rear interface in case of power abnormality such as power loss or voltage instability. Operating status of each functional module is fed back to the CPU module via the bus. Once module faults or vibration data exceed preset thresholds, the system outputs alarm signals through relay modules to remind maintenance personnel and prevent fault escalation.
Data Transmission & Interaction: The rack supports Modbus RTU/TCP, Profinet and other protocols. It establishes connection with external industrial networks and monitoring terminals via the CPU module to realize real-time uploading of vibration data and equipment status as well as remote control, supporting predictive maintenance and remote equipment monitoring.

Core Logic: Taking the rack as the carrier, the backplane bus realizes power distribution and data interaction among modules, constructing a modular and expandable vibration monitoring system. It enables continuous vibration condition monitoring, data analysis and fault early warning for industrial machinery to ensure safe and stable equipment operation.
