VMIC VMEbus Modules and National Instruments DAQ Components: Complete Sourcing Guide
VMEbus-based industrial computing platforms and National Instruments data acquisition hardware represent two of the most enduring legacy technology families in industrial test, measurement, and automation. VMIC (now Abaco Systems / GE Fanuc heritage) VMEbus modules and National Instruments PCI, PCMCIA, and MXI interface products are installed across power generation, defense, aerospace, transportation, and advanced manufacturing systems worldwide.
Both product families share a common sourcing challenge: many models are discontinued or nearing end-of-life, but the systems they support continue to operate in active production and test environments with long replacement cycles. When a VMIVME single board computer fails, or a National Instruments Foundation Fieldbus interface card requires replacement, sourcing the correct part quickly requires a supplier with genuine verified inventory.
This guide covers the most in-demand VMIC VMEbus and National Instruments components currently driving search traffic and sourcing requests with part numbers, specifications, and direct links to availability at Industrial Partner.

VMIC VMEbus Single Board Computers — VMIVME-7648 Series
The VMIVME-7648 series represents the GE VMIC / Abaco heritage of Intel Pentium III-based VMEbus single board computers — one of the most widely deployed embedded computing platforms in industrial VMEbus systems. These SBCs integrate the processor, memory, video, Ethernet, USB, and serial communications on a single VME-format board, providing a complete embedded computing node within a VMEbus chassis.
The VMIVME-7648 architecture uses dual independent bus architecture for high-bandwidth memory access, with 256KB of L2 cache and a VME 64 connector for backplane communication. Its combination of processing performance and I/O integration made it a standard specification in power plant control rooms, simulation systems, and industrial data acquisition racks during its production run.
Both VMIVME-7648 variants are stocked at Industrial Partner. Browse VMIC VMEbus SBC modules or request a quote.
VMIC VMEbus Digital I/O Modules
VMIC's VMEbus digital I/O boards provide the interface between VMEbus processor systems and field digital signals — switches, sensors, actuators, and external control systems. The VMIVME digital I/O family covers TTL-level I/O, high-voltage isolated I/O, and reflective memory for distributed control architectures.
VMIVME-2532A — 32-Bit Digital I/O Module
VMIVME-1101 — 32-Bit TTL Digital Input with Change-of-State Interrupts
VMIVME-2528 — 128-Bit TTL Digital I/O
Browse VMIC digital I/O boards at Industrial Partner — including VMIVME-2532A, VMIVME-1101, and VMIVME-2528.
VMIC VMEbus Reflective Memory Modules — VMIVME-5550
Reflective memory is a specialized shared memory architecture used in distributed real-time systems where multiple processors or nodes must share data with deterministic, low-latency communication. VMIC's VMIVME-5550 Multidrop Reflective Memory with Interrupts is one of the most widely used reflective memory solutions in VMEbus-based real-time systems — deployed across power plant simulators, flight simulators, industrial process control, and real-time test systems.
The reflective memory architecture allows any write to the local memory of one node to be simultaneously and automatically replicated to the corresponding memory location of all other nodes on the network — without processor intervention. This provides the real-time data sharing performance that polling-based communication protocols cannot match.
VMIVME-5010 — VMEbus Interrupt Expander
Industrial Partner stocks VMIVME-5550 reflective memory modules and VMIVME-5010 interrupt expanders. Browse VMIC modules or request a quote.
National Instruments Foundation Fieldbus Interface — PCMCIA-FBUS-2
Foundation Fieldbus (FF) is a digital industrial communication protocol used in process automation to connect field instruments — flow meters, pressure transmitters, temperature sensors, control valves — to control systems and DCS platforms. National Instruments' PCMCIA-FBUS-2 provides Foundation Fieldbus H1 communication capability in a PCMCIA Type II card format, making it the interface of choice for portable configuration, commissioning, and diagnostic systems in FF-equipped process plants.
The PCMCIA-FBUS-2 is one of the most frequently searched National Instruments legacy interface components. Browse NI Fieldbus interface components at Industrial Partner.
National Instruments MXI VMEbus Interface — VME-MXI
MXI (Multisystem eXtension Interface) is National Instruments' high-bandwidth bus extension architecture that connects PC hosts (via ISA, PCI, or PXI interfaces) to VMEbus or VXIbus instrument chassis over standard cabling. The VME-MXI board installs in the VMEbus chassis and provides the VMEbus-side interface for MXI communication, enabling PC-based control and data acquisition from VMEbus instruments and I/O modules.
The VME-MXI and its PC-side counterpart (the PCI-MXI-2 or AT-MXI-2) have been widely used in industrial test systems, simulation, and automated test equipment (ATE) where VMEbus instruments must be controlled from a PC environment. The MITE ASIC integrated into NI MXI hardware enables dual-channel DMA with VME64 MBLT transfers, achieving sustained data transfer rates significantly higher than programmed I/O alternatives.
National Instruments PCI Data Acquisition and Digital I/O Cards
National Instruments' PCI-format data acquisition cards provide analog I/O, digital I/O, and counter/timer functions in standard PCI slots for industrial PC-based measurement and control systems. The PCI-7314 and PCI-6503 represent two distinct NI PCI DAQ card categories with different application profiles.
PCI-7314 — Analog Output for Motion Control
PCI-6503 — 24-Channel Digital I/O

Sourcing Discontinued VMIC and NI Components
Both the VMIC VMEbus and NI legacy PCI/PCMCIA product families present similar sourcing challenges. VMEbus as a bus standard peaked in industrial deployment during the 1990s and early 2000s, and VMIC's product line was acquired by GE Fanuc and subsequently by Abaco Systems. Many VMIVME modules are discontinued, but the VMEbus systems they populate in power plants, simulators, and industrial facilities continue to operate with no near-term replacement plans.
National Instruments has similarly transitioned its core product line from legacy PCI-format DAQ cards toward PXI, USB, and Ethernet instruments. The PCMCIA-FBUS-2, VME-MXI, PCI-7314, and PCI-6503 are all legacy products for which NI no longer manufactures new units, but active demand from installed systems keeps search volumes high.
For systems engineers and maintenance teams managing these platforms, the key sourcing considerations are:

Conclusion
VMIC VMEbus modules and National Instruments data acquisition and interface hardware represent two of the most enduring and technically demanding legacy product families in industrial computing. The VMIVME-7648 single board computers, VMIVME-2532A and VMIVME-2528 digital I/O boards, VMIVME-5550 reflective memory, and VMIVME-1101 digital input modules form the core of thousands of active VMEbus systems in power generation, simulation, and process control environments. The NI PCMCIA-FBUS-2, VME-MXI, PCI-7314, and PCI-6503 serve active fieldbus commissioning, VMEbus instrument control, and PC-based automation applications.
For all of these components, sourcing requires a specialist supplier with verified stock, hardware revision expertise, and the ability to confirm component health before dispatch. Industrial Partner maintains inventory across both product families for exactly these requirements.
