Description
The Xycom (later Xembedded / Acromag) XVME-976 is a specialized industrial adapter and expansion module engineered for VMEbus-based computing architectures. It functions primarily as a dual-slot PC expansion/adapter module designed to interface specific daughter cards or auxiliary hardware extensions within a standard VMEbus chassis environment.

Supply Terms & Commercial Details
- Availability: As a legacy hardware component, factory-new stock is obsolete. Sourcing is handled via specialized industrial automation surplus, secondary hardware brokers, or pre-tested refurbished parts suppliers.
- Lead Time: In-stock surplus components typically ship within 3 to 5 business days.
- Warranty: 12-month standard supplier replacement or repair warranty (verify specific terms depending on whether the unit is surplus or refurbished).
- Condition: New Surplus, Factory Open Box, or Fully Tested Refurbished (confirm exact cosmetic and operational state upon inquiry).
- Pricing Note: Market pricing varies due to obsolescence and scarcity; contact your vendor for a formal quotation.
Engineering & Integration Guidance
When integrating or replacing the XVME-976 module within a VMEbus enclosure, observe the following technical parameters:
- Electrostatic Discharge (ESD) Handling: Always wear a grounded antistatic wrist strap and handle the card by its edges or faceplate to prevent electrostatic breakdown of sensitive onboard bus logic.
- Backplane Power Safety: Completely de-energize the entire VME chassis before inserting or extracting the module. Live backplane insertion can cause severe bus lockups, electrical arcing, or pin damage.
- Slot Alignment & Daughter Cards: Ensure the dual-slot layout aligns accurately with internal backplane connectors and any connected expansion daughter cards are securely fastened to prevent shifting under industrial vibration.
Frequently Asked Questions
What system architecture uses the Xycom XVME-976?
The XVME-976 is built specifically for legacy Xycom VMEbus industrial computer platforms requiring slot-based hardware expansion or adapter mapping.
Is the XVME-976 a standalone CPU board?
No. It functions as an adapter/expansion module designed to support system configuration flexibility rather than acting as a primary standalone processor card.
Can this module be hot-swapped?
No. Standard VMEbus systems of this generation do not support hot-swapping. Always shut down system power completely before servicing rack modules
