XYCOM XVME-660716 – VME I/O board for extending legacy industrial control systems

The XYCOM XVME-660716 is a 6U VMEbus plug-in module from the long-running XVME family, widely used to expand I/O capacity in legacy machine control, test stands, and process systems. From my experience, this series is picked when a plant wants to keep a stable VME platform running but needs extra channels or a direct form/fit replacement without rewriting the whole application. The “-716” build code denotes a specific signal option and channel count within the 660 family. If you can share your backplane, signal levels, and channel requirements, we’ll validate the exact fit before shipping—saves headaches on site.

Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL
• Pre-shipment verification: we confirm the -716 option matches your I/O type and slot/backplane before dispatch

Key Features

• 6U VMEbus form factor – Fits standard 19-inch VME chassis; easy drop-in for existing racks.
• Backplane-powered – Draws primary power from +5 V via P1/P2; auxiliary ±12 V rails may be used depending on the option.
• Option-coded (-716) build – The suffix defines the signal type and channel count; we verify this so your wiring lines up first time.
• Lifecycle-friendly – Ideal for installed-base support where requalification costs are high. You might notice this board shows up in long-service equipment.
• Status indicators and test points – Typically present on XVME boards, helpful for quick diagnostics during commissioning.
• Field-proven reliability – In many cases these modules run 24/7 in harsh panels—stable and predictable once installed correctly.

Technical Specifications

Related or Supporting Products

• 6U VME Chassis/Subrack (Schroff/Elma types) – 7 to 12 slots, forced-air cooling. Good match when expanding an existing rack.
• 96‑pin DIN 41612 Transition Board or DIN‑rail Breakout – Routes the front/rear I/O to screw terminals; reduces field wiring time.
• VME Power Supply (5 V/60 A class with ±12 V rails) – Stable rails are key; aging PSUs are often the hidden fault in legacy systems.
• Cable/Harness Kits matched to the -716 pinout – We can produce labeled harnesses to your wire spec, saves a few hours during commissioning.

One thing I appreciate is how smoothly these boards slot into older GE Fanuc/Xycom-based racks—most customers just want the same faceplate, pinout, and timing. A maintenance lead recently told us the swap took under 30 minutes once the panel was open, largely because the rear wiring didn’t have to move.

Installation & Maintenance

• Cabinet & cooling – Install in a standard VME subrack with adequate airflow; keep intake filters clean and allow clear exhaust.
• Wiring & grounding – Use shielded cable for noisy environments; bond shields at a single reference point. Verify the -716 pinout before landing field wires.
• ESD safety – Handle with a grounded wrist strap; insert and remove using the ejector levers to avoid flexing the backplane.
• Firmware/config – If the -716 variant uses any onboard configuration (jumpers or firmware), mirror your existing settings before power-up.
• Routine checks – Quarterly visual inspection for loose connectors, dust on heatsinks, and backplane pin oxidation. Re-seat once a year if the site is high-vibration.
• Calibration (if applicable) – For analog options, schedule calibration annually; for digital-only, a functional I/O loop test is usually sufficient.

Quality & Certifications

• CE/UL marks were commonly supplied on XVME-series units at the time; documentation can be provided per serial/lot.
• RoHS: legacy exemptions may apply depending on build date; we can quote compliant alternatives when needed.
• Each unit is function-tested before shipping, with a 365-day warranty.

If you share your exact XVME crate model, backplane type, and the required I/O levels for “-716”, we’ll confirm compatibility and reserve stock for your job window.
