GE QuickPanel HMI, Series Six PLC, Horner Analog Modules and Basler Sync-Check Relay Spare Parts
Four of the most actively searched industrial legacy component families in today's MRO market share a common thread: they are all discontinued by original manufacturers, they all remain operational in active production and power systems, and finding verified replacement stock requires a specialist supplier. This guide covers the most in-demand parts from GE QuickPanel HMI touchscreens, GE Fanuc Series Six PLCs, Horner Electric HEC analog I/O modules, the Basler BE1-25 synchronizing check relay, and VMIC's high-speed reflective memory — each a critical component in systems that cannot easily be upgraded or replaced without major capital expenditure.
Industrial Partner stocks GE QuickPanel HMI panels, GE Series Six PLC boards, Horner HEC analog modules, Basler protection relays, and VMIC VMEbus memory — including discontinued and hard-to-find variants. Browse GE components · Request a quote.
GE QuickPanel HMI Touchscreens — QPI-31200 Series
The GE QuickPanel series — developed by Total Control Products and later produced under the GE Fanuc brand — was one of the most widely deployed industrial HMI touchscreen platforms of the 1990s and early 2000s. QuickPanel units are operator interface terminals that combine a touchscreen display, an embedded PLC, and I/O in a single panel-mount enclosure. They are programmable via GE's QuickDesigner and QuickWorX software environments.
Despite being discontinued by GE, QuickPanel HMI units remain in active service in manufacturing, packaging, water treatment, and building automation environments worldwide. When a QuickPanel display fails — typically due to backlight degradation, touchscreen wear, or power supply failure — a replacement unit must match the original model's physical dimensions, communication interfaces, and software compatibility.
The QPI-31200 series covers several display technology and communication variants, each with a distinct part number suffix:

GE Fanuc Series Six PLC — IC600 Series CPU and I/O Modules
The GE Fanuc Series Six is one of GE's earliest programmable logic controller platforms, introduced in the 1980s and now long discontinued. Despite its age, Series Six PLCs continue to control equipment in legacy manufacturing environments — particularly in industries where control system replacement carries high downtime risk and capital cost. The IC600 prefix identifies Series Six hardware.
The Series Six architecture uses modular CPU boards, I/O rack modules, and communication boards in a plug-in backplane format. When a Series Six CPU or I/O board fails, replacement sourcing is exclusively through the industrial MRO aftermarket — GE Fanuc ceased all new production of IC600 series hardware decades ago.

Horner Electric HEC Analog I/O Modules for Hitachi EMTM and Reliance Shark PLCs
The Horner Electric HEC analog module series was developed specifically as 12-bit analog I/O expansion for Hitachi EMTM and Reliance Electric Shark PLC platforms. The HEC-DAC (Digital-to-Analog Converter) modules provide voltage and current analog output capability, while the HEC-ADC (Analog-to-Digital Converter) modules provide analog input acquisition. These modules are all discontinued but remain in active service in legacy Hitachi and Reliance-based automation systems.
The HEC module range uses a direct backplane connection to the host PLC rack and communicates via the PLC's internal I/O bus — they are not standalone modules and must be matched to a compatible host PLC system. When a module fails, an exact part number replacement is required; the modules are not cross-compatible across the HEC-DAC and HEC-ADC sub-families.

Basler Electric BE1-25 Synchronizing Check Relay
The Basler Electric BE1-25 is a solid-state synchronizing check relay used in power generation and utility switching applications to verify that safe synchronizing conditions exist before a circuit breaker is closed to connect a generator or power source to a live bus. It monitors the voltages on both sides of the circuit breaker and verifies that acceptable phase angle and voltage magnitude conditions exist prior to authorizing breaker closure.
The BE1-25 is a critical protection component in generator paralleling, utility interconnection, and grid-tie applications. A failed or malfunctioning sync-check relay can prevent generator paralleling operations or, in a fault condition, allow a breaker to close out of synchronism — a potentially damaging event for large generators and transformers.
The BE1-25 monitors:
The BE1-25 is available in semi-flush and drawout mounting configurations and has been superseded by Basler's BE3-25 digital version, but original BE1-25 solid-state units are still required for direct replacement in existing panel installations where mounting cutout and wiring are fixed.

VMIC VMIVME-5588DMA — High-Speed Fiber-Optic Reflective Memory
The VMIVME-5588DMA is VMIC's enhanced single-slot high-speed fiber-optic reflective memory module with DMA (Direct Memory Access) capability — the highest-performance variant in the VMIC reflective memory family. Unlike the standard VMIVME-5550 multidrop reflective memory, the 5588DMA uses point-to-point fiber-optic connections and DMA transfer architecture to deliver significantly higher data rates and lower latency for real-time distributed computing applications.
Reflective memory technology allows any processor node that writes to its local memory to have that write automatically replicated to all other nodes on the reflective memory network simultaneously — without interrupting the node's processor or requiring software communication protocols. This makes the VMIVME-5588DMA the component of choice in applications requiring deterministic, microsecond-latency shared memory across multiple VMEbus systems, including:
The VMIVME-5588DMA is among the highest-value VMIC components currently in demand. Browse VMIC reflective memory modules at Industrial Partner — including VMIVME-5588DMA and VMIVME-5550 variants.
Why These Components Are Difficult to Source
The five product families covered in this guide share common sourcing characteristics that explain why they continue to drive high search traffic despite being discontinued:

Conclusion
The GE QuickPanel QPI-31200 HMI touchscreens, GE Fanuc Series Six IC600BF907 PLC boards, Horner Electric HEC-DAC-40, HEC-DAC-44, and HEC-ADC-80B analog modules, Basler Electric BE1-25 sync-check relay, and VMIC VMIVME-5588DMA high-speed reflective memory represent some of the most actively searched and hardest-to-source legacy industrial components in today's MRO market. Each is discontinued by its original manufacturer but continues to be required for maintenance of active systems with long remaining operational lives.
For maintenance teams managing these platforms, working with a specialist industrial MRO supplier who maintains verified, tested inventory, and who can confirm hardware revisions and compatibility is the most reliable path to fast, successful sourcing.
