The VMIVME-7455 is a high-performance 6U single-slot VMEbus module originally developed by VMIC (now part of the GE Intelligent Platforms/Emerson industrial ecosystem). It serves as a versatile, ruggedized single-board computer (SBC) designed for demanding real-time control, data acquisition, and signal processing applications. It is widely recognized for its deterministic performance in mission-critical environments, including aerospace, defense, and industrial power generation control racks.

Technical Specifications

Operational & System Features

• ⚙️ System Compatibility: Engineered for standard 6U VMEbus backplanes, ensuring interoperability with a wide array of legacy and modern industrial modules.

Key Operational Considerations

• Jumper Configuration: The VMIVME-7455 relies on physical board jumpers and switches to set base memory addresses, VMEbus priority, and interrupt levels. Ensure these match your system’s memory map exactly during installation.

• Thermal Management: Despite the module’s industrial rating, ensure that the control cabinet has active airflow (fans) to prevent localized overheating, especially in high-density VME racks.

• Board Revision: Be aware that “A,” “B,” or “C” revisions of the 7455 may have different processor speeds or memory capacities. Always consult the specific technical manual for your board’s revision before performing a firmware update.
