Description
Motorola MVME162-283
Technical Specifications
- Processor Architecture: Based on the MC68040 enhanced 32-bit microprocessor.
- Memory: 4MB to 16MB shared DRAM with parity protection.
- Interfaces: 4 IndustryPack ports, optional SCSI bus interface, and Ethernet interface.
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 to save overall investment.
- Data Integrity: Memory supports parity protection to prevent data flipping caused by cosmic rays or electromagnetic interference.
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 to improve oxidation resistance.
Structural Characteristics
Standard 6U VME size, front panel provides status indicator lights and optional physical SCSI/Ethernet 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 to prevent internal short circuits.
- Ensure termination resistors are correctly configured when using the SCSI interface.
