Description
Motorola MVME162-531A
Technical Specifications
- Processor: Enhanced MC68040 32-bit microprocessor.
- Memory: 4MB to 16MB shared DRAM with parity protection.
- Interfaces: 4 IndustryPack ports, optional SCSI and Ethernet.
- Non-Volatile Storage: NVRAM and TOD clock.
Functional Features
- High-Reliability Architecture: Uses industrial-grade components; maintains stable performance after 1000 hours of continuous salt spray testing.
- Flexible Configuration: Users can flexibly configure I/O, control, or interface functions.
- Data Integrity: Memory supports parity protection to prevent data flipping.
- Remote Management: Supports remote RESET/ABORT/STATUS control functions.
Application Scenarios
Suitable for offshore platform monitoring, chemical process control, and metallurgical automation in corrosive or high-interference environments.
Performance Parameters
- Humidity Tolerance: Relative humidity 5% to 95% (non-condensing).
- Bus Performance: Supports Block Transfer (BLT) from local bus to VME bus.
Material Composition
PCB surface is treated with special anti-corrosion conformal coating, and connectors are gold-plated.
Structural Characteristics
Standard 6U VME size, front panel provides status indicator lights and optional physical interfaces.
Working Principle
Collaborates with other I/O modules via the VME bus. The processor executes control algorithms and directly drives or reads field devices through the IndustryPack interface.
Installation Requirements
- Ensure P1 and P2 backplane connectors are free from oxidation or bending.
- Tighten front-panel mounting screws after installation to ensure proper grounding.
Usage Precautions
- Avoid long-term operation in environments exceeding specified humidity levels.
- Ensure termination resistors are correctly configured when using the SCSI interface.
