Industrial Control System CPU Solution – Konmask VMIVME-7671-421000 | GE VMEbus Series
In mission-critical industrial environments — power generation plants, petrochemical refineries, and large-scale manufacturing lines — unplanned downtime costs an average of $260,000 per hour (Aberdeen Group). The root cause is often a failed or obsolete processor board buried inside a legacy VMEbus-based DCS or SCADA rack. Replacement lead times from OEMs can stretch 16–26 weeks, leaving facilities running on degraded redundancy or forced into costly emergency shutdowns. Engineers need a verified, drop-in replacement that restores full system integrity — fast.
The GE VMIVME-7671-421000 is a high-performance VMEbus single-board computer engineered for exactly these scenarios. Built on the VME64 standard with a ruggedized design rated for extended industrial temperature ranges, this processor board slots directly into existing GE VMIC VMEbus backplanes, restoring full computational capacity without requiring software reconfiguration, I/O rewiring, or system re-commissioning. Konmask.com maintains verified stock, fully tested to factory specifications, with global dispatch within 24–48 hours.

Application-Specific FAQ
Q: Can the VMIVME-7671-421000 replace the CPU in a GE Mark V turbine control system without re-engineering the I/O subsystem?
A: In most Mark V migration architectures, the VMIVME-7671-421000 serves as the replacement host processor within the VMEbus rack. The existing I/O boards (VMIVME-3113A analog input, VMIVME-2536 digital I/O) remain in place. The key requirement is that the replacement CPU runs the same OS image and application software as the original board. We recommend requesting the firmware version readout from our test report to confirm compatibility before ordering. Contact our team for a site-specific compatibility assessment.
Q: Is this board suitable for SIL 2 emergency shutdown system (ESD) applications in a petrochemical plant?
A: The VMIVME-7671-421000 is a general-purpose industrial processor board and is not independently SIL 2 certified as a standalone component. However, it is used as a co-processor or host CPU within SIL 2 architectures where the safety function is implemented at the system level (IEC 61511 / IEC 61508 system approach). Your functional safety engineer should assess the board’s role within the overall Safety Instrumented System (SIS) architecture. We can provide full test documentation and CoC to support your safety case documentation.
Q: What is the typical lead time for VMIVME-7671-421000 in a water treatment SCADA master station replacement project, and can you support multiple units for a phased rollout?
A: For in-stock units, dispatch occurs within 24–48 hours of order confirmation. For phased rollout projects requiring 3–10+ units over a 6–12 month period, we offer reserved stock agreements — we hold your allocated quantity at a confirmed price, releasing units on your project schedule. Contact support@konmask.com to discuss volume pricing and phased delivery terms.
