XYCOM XVME-6744 – VMEbus I/O and Control Module for Legacy Industrial Systems
The XYCOM XVME-6744 belongs to the classic XVME family used widely in VME-based control racks. From my experience, this board is typically deployed as a robust I/O and control interface for machine tools, test stands, and semiconductor tools where reliability matters more than fancy features. You might notice that teams keep these modules in service because they fit straight into existing 6U VME slots and just work—minimal disruption, predictable behavior, and parts you can maintain in-house.
If you’re maintaining a legacy line or extending the life of an installed VME system, the XVME-6744 gives you a practical path: consistent VMEbus integration, straightforward wiring via front-panel connectors or breakouts, and the kind of signal handling that keeps PLCs, sensors, and relays in sync. One thing I appreciate is how serviceable these boards are—clear status indication in most cases and standard VME mechanics that make swaps quick.

Key Features
- Standard 6U VME form factor – Fits common VME card cages, easing drop-in replacement and field swaps.
- Backplane-powered, no external PSU – Draws regulated +5 VDC from the VME backplane; wiring stays tidy.
- Industrial I/O readiness – Designed for digital I/O/control use cases typical of the XVME series; suitable for sensors, relays, and machine interlocks.
- Deterministic bus behavior – VMEbus timing and interrupts (as implemented on the XVME family) support predictable control cycles in most cases.
- Service-friendly front panel – Access to connectors and indicators at the rack face; simplifies troubleshooting and commissioning.
- Proven in legacy equipment – Common in older production assets where low risk and long service life are priorities.
Technical Specifications
The XVME-6744 is part of XYCOM’s VMEbus I/O/control family. Exact channel counts and connector styles can vary by sub-revision; the essentials below reflect what you typically see on this line. If you need us to verify a specific hardware revision, we’re happy to check photos and test reports before shipment.

- VMIC VMIVME-2128 – 64‑channel isolated digital I/O module for VME; a common alternative when higher channel density is needed.
- VMIC VMIVME-3122 – Multi‑channel analog input for VME systems; often paired with digital I/O boards in data acquisition racks.
- 6U VME Chassis & Backplanes – 7–13 slot VME/VME64x cages with forced‑air cooling; choose slot count and power budget to match your rack.
- VME Power Supply (5 V / 12 V rails) – Industrial VME supplies sized to system load; make sure +5 V margin covers peak I/O current.
- Shielded Breakout & Cables – 50/68‑pin shielded ribbon or D‑sub harnesses plus DIN‑rail terminal breakout boards to simplify field wiring.
Quick field note: a maintenance lead at a wafer fab told us they swapped an XVME board like this in under 20 minutes—card out, seat the replacement, tighten the front panel, re‑seat I/O, back in service. That seems to be the norm when the backplane and pinout are kept consistent.
Installation & Maintenance
- Cabinet & Cooling – Install in a 6U VME chassis with adequate airflow. Keep intake filters clean; typical target is balanced front‑to‑back airflow across cards.
- Power Budget – Verify +5 V backplane capacity with 15–20% headroom. Shared supplies on older racks can sag under peak I/O loads.
- Wiring – Use shielded cables for noisy environments. Maintain proper strain relief on front-panel connectors and avoid tight bend radii.
- ESD & Handling – Observe ESD precautions; handle by the front panel and edges. Seat the DIN 41612 connector fully in the card guides.
- Configuration – Document jumper or switch positions before replacement. In many cases, interrupt vectors and base addresses are set via headers or DIP switches.
- Routine Care – Quarterly: check retention screws, clean dust, and visually inspect capacitors/connectors. Annual: review logs for intermittent I/O, re‑seat if needed.
- Firmware/PLD – Some units have programmable logic or microcode. Keep a record of the board revision for consistent behavior across spares.
Quality & Certifications
- CE marking is typically present on later production of XVME boards for EMC compliance.
- UL/CSA often as Recognized Component for use in industrial control equipment.
- RoHS compliance depends on manufacturing date; many legacy units predate RoHS and are maintained under repair/return exemptions.
- Manufacturer warranty: we provide a 365‑day warranty on this unit, with advance replacement or repair support depending on stock.
If you share your current rack photo or the XVME‑6744 sub‑revision, we can confirm connector style, I/O type, and test it to your checklist before shipping. That tends to eliminate surprises during the swap.
