Performance Parameters
- Bus Standard: VMEbus (supports A32/D32 data transfer).
- Expansion Capability: Provides two VME expansion slots.
- Operating Systems: Supports VxWorks, pSOS, Linux, and UNIX SYSTEM V/68.
Material Composition
Manufactured with industrial-grade high-reliability electronic components; features a multi-layer PCB design offering excellent anti-interference capabilities and signal integrity.
Structural Characteristics
Compact industrial standard dimensions (160mm x 100mm), weighing approximately 0.5kg. Designed for VME chassis card-slot installation, saving space and ensuring easy integration.
Operating Principle
Exchanges high-speed data with the system backplane via the VME bus. The processor reads input signals from external sensors or controllers, performs internal logical computations, and outputs control commands via on-board I/O interfaces or the bus for precise real-time control.
Installation Requirements
Must be installed in a VME-standard chassis backplane slot, ensuring connectors are perfectly aligned and locked. The system must provide a stable 5VDC ±5% power supply with a maximum current of no less than 2.5A.
Usage Precautions
Operating temperature must be maintained between 0°C and 50°C, with humidity between 5% and 95% (non-condensing). Strict electrostatic discharge (ESD) precautions are required during operation; never insert or remove the module while powered on.
