GE VMIVME-7486 | VMEbus Series 100% PC/AT Compatible Processor Board

Description

VMIVME-7486: 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 Ethernet or serial ports).
3. Legacy Support: Serves as a drop-in replacement for older VMEbus processor boards, extending the lifespan of existing industrial systems without requiring major upgrades.

• 100% PC/AT Compatibility: The VMIVME-7486 is fully compatible with PC/AT systems, allowing seamless integration with existing software and hardware ecosystems.
• VMEbus Integration: Conforms to VMEbus Rev. C.1, supporting 8/16/32-bit data transfer and seamless integration with VME64 backplanes and controllers (e.g., GE Fanuc 90-30 series).
• Advanced Chipset: The Intel 815E chipset with Advanced Hub Architecture (AHA) separates high-bandwidth I/O (e.g., IDE, USB) from the PCI bus, reducing bottlenecks and improving system performance.
• Robust I/O Capabilities: Includes a parallel Centronics port, two RS-232C serial ports, a PC/AT keyboard interface, and on-board floppy/IDE controllers, enabling connection to a wide range of peripherals.
• Real-Time Clock (RTC): Features an on-board RTC with a battery backup, ensuring accurate timekeeping even during power outages.

• 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 with additional I/O modules or memory to accommodate growing system demands.
• Legacy Integration: Compatible with existing VMEbus systems, reducing the cost and complexity of upgrading industrial control architectures.
