GE VMIVME-7765 | VMEbus Series Dual-Pentium III Single-Board Computer

Description

VMIVME-7765: Product Overview​

1. Data Processing: Executes control algorithms and processes data from field devices (e.g., sensors, actuators) via the VMEbus.
2. Communication: Acts as a system controller or peripheral CPU, enabling communication between VMEbus devices (e.g., I/O modules, displays) and external networks (via dual Ethernet ports).
3. Legacy Support: Serves as a drop-in replacement for older VMEbus SBCs, extending the lifespan of existing industrial systems without requiring major upgrades.

• VMEbus Compatibility: Conforms to VMEbus Rev. C.1, ensuring seamless integration with VME64 backplanes and devices. The transparent PCI-to-VMEbus bridge allows it to function as a system controller or peripheral CPU in multi-CPU systems.
• Flexible I/O: Includes 2× 16-bit programmable timers, 32 KB non-volatile SRAM (for data retention during power outages), and a PMC expansion site for adding custom I/O (e.g., fiber optic communication, AI acceleration).
• High-Performance Processing: The dual Intel Pentium III processors (up to 1.26 GHz) with 512 KB advanced transfer cache deliver fast data processing, critical for real-time control applications like turbine management or manufacturing automation.
• Passive Cooling: Designed for passive cooling (no fans), reducing maintenance requirements and improving durability in dusty or high-vibration environments.

• Reliability: Industrial-grade components and a rugged 6U Eurocard form factor ensure 24/7 operation in harsh environments (e.g., high temperature, vibration).
• Scalability: Supports expansion via PMC modules, allowing users to add functionality (e.g., additional I/O, networking) without replacing the SBC.
• Legacy Integration: Compatible with existing VMEbus systems, reducing the cost and complexity of upgrading industrial control architectures.
