XYCOM XVME-95612 – VMEbus I/O/Communications Module for Extending Legacy Control Systems
The XYCOM XVME-95612 is a VMEbus plug-in module designed for industrial control racks that need reliable, long-term I/O and communications expansion. It fits standard 6U VME enclosures and, in many cases, is used to add field connectivity—often serial or digital—to legacy XYCOM-based systems without rewriting the whole control stack. From my experience, teams choose this board when they need a drop-in card to keep semiconductor tools, test stands, power generation systems, or packaging lines operating with minimal downtime.

Key Features
- VMEbus compatibility – Designed for ANSI/IEEE 1014 VME systems, making it a straightforward fit for existing racks.
- 6U form factor – Standard 6U board height typically used across XYCOM XVME installations, easing mechanical integration.
- Field I/O expansion – Commonly deployed to add multi-channel serial or digital interfacing to legacy controls; you might notice shorter commissioning time versus a full system swap.
- Backplane-powered – Receives power via the VME backplane (5 VDC primary; ±12 V rails used in many cases), reducing external wiring.
- Service-friendly design – Front-panel access for cabling and diagnostics helps maintenance teams isolate issues quickly.
- Lifecycle extension – A practical path to extend installed assets while keeping validated software and I/O mappings intact.
One thing I appreciate is how these XVME modules keep older control platforms viable without forcing a platform migration. A packaging OEM recently used the XVME-95612 to bring eight legacy drives and several barcode readers back online after a rack refresh—the work mostly involved cabling and addressing, not requalification.

Related or Supporting Products
- XYCOM XVME series CPU boards (for system control) – pairs with the XVME-95612 to handle application logic and bus management.
- VME64x or classic VME 6U chassis and backplanes – required for mechanical mounting and power distribution.
- Front-panel cable kits and breakout panels – simplify field wiring for serial/discrete signals.
- Industrial PSUs for VME racks – stabilized 5 V and ±12 V rails for reliable backplane power.
- Alternative VME I/O modules (analog input/output, relay output, high-speed serial) – chosen based on the exact channel mix needed.
If you’re replacing a retired board, send the installed backplane address map and connector pinout photo. Matching those details typically shortens switchover by a day or two.
Installation & Maintenance
- Cabinet & ventilation – Install in a compliant 19-inch VME chassis with unobstructed airflow. Maintain clean intake filters; target ambient 25–35 °C where possible.
- Power & grounding – Verify stable 5 V backplane within tolerance; bond chassis ground to plant earth. Avoid ground loops on field shields.
- Wiring – Use shielded cables for serial/low-level signals. Keep field wiring segregated from motor drives and VFD leads.
- Addressing & jumpers – Set VME address, interrupt level, and any serial mode jumpers per your rack standard. Label settings for future service.
- Routine maintenance – Quarterly: reseat the card, inspect front-panel connectors, and remove dust with dry air. Annually: review firmware/driver versions used by the host CPU and back up configuration files.
- Safety – De-energize the rack before insertion or removal. Use ESD protection when handling the board.
Quality & Certifications
- Typically compliant with CE for EMC when installed in a suitable VME enclosure.
- UL recognition often applies at the rack/system level; check the specific chassis listing.
- Manufactured under ISO 9001 quality systems (typical for the series).
- RoHS status may vary by production year; many legacy VME boards predate RoHS and require system-level review.
- Warranty: 365 days from shipment.
If you’re unsure whether the XVME-95612 matches your channel mix, share the existing board part code and a close-up of the front panel. We can typically cross-check pinouts and suggest a compatible build without changing your ladder or host application.
