Product details
GE IS415UCVHH1A Mark VIe VME Controller Board
The IS415UCVHH1A is a VME controller board from GE’s Mark VIe Turbine Control System series. It runs turbine application code on an Intel Ultra Low Voltage Celeron 650 MHz CPU. The board uses QNX, a fast real-time OS built for industrial tasks. It supports simplex, dual, and triple-redundant setups. This gives you flexible redundancy at lower cost. The IS415UCVHH1A connects to I/O boards through the VME bus. It mounts in a VME rack called a control module. ControlST software gives you one source of high-quality, time-coherent data. You can analyze and adapt your plant in real time. This unit carries conformal coating for harsh plant environments. It is a later Mark VIe revision, not the first VME board GE made for the series.

Performance and Operation
- Runs up to 100,000 rungs or blocks per second (average block size)
- Syncs to the VCMI board clock within 100 microseconds via external clock interrupt
- VCMI board moves external data to and from the controller CSDB over the VME bus
- Handles steam, gas, land-marine derivative (LM), and balance of plant (BOP) software
- Mix and match controller and I/O redundancy to fit your application and cut cost
Installation Guide
- Each control module holds two parts: the controller and a VCMI board
- Three rack types fit this module: GE Fanuc integrator rack, short Mark VIe rack, and long Mark VIe rack
- Short GE Fanuc rack runs standalone modules with remote I/O only
- Long Mark VIe racks support both local and remote I/O
- A cooling fan sits above or below the controller, based on rack type
- Standalone module in a GE Fanuc rack needs a VDSK board for fan power and rack ID
- Confirm power feed at 200–250 Vac before power-up
Maintenance and Diagnostics
- Use ControlST software to program, configure, and read diagnostics
- Watch the 5 faceplate alarm LEDs for quick fault checks
- Battery (CMOS) is replaceable; plan periodic checks
- Keep airflow clear around heatsinks and the cooling fan
- Conformal coating protects the PCB from dust and moisture
Compatibility Notes
- Fits Mark VIe control modules with VCMI bus master boards
- Works with GE Fanuc integrator racks and standard Mark VIe racks
- Pairs with Mark VIe I/O boards over the VME bus
- Supports simplex, dual, and triple-redundant (TMR) architectures
- Check firmware and ControlST version before swap
Certifications and Quality
- Made in USA by General Electric
- Conformal coating for plant-floor durability
- Built for gas, steam, and wind turbine control duty
- Manual reference: GEH-6421 M
Expert Review
“This board is the brain of a Mark VIe module. The QNX OS keeps loop timing tight. The 100-microsecond VCMI clock sync matters for TMR voting. Conformal coating is a plus in humid plants. Swap one in, load your application, and it runs.” — Powergear X Engineering Team
Manager’s Insight
“Buyers ask for the H revision because it is the later build. We stock tested units with clear revision labels. Need a quote fast? Email sales@powergearx.com or message +86 18030005825 on WhatsApp.” — Sales Manager, Powergear X
Ideal Equipment and Applications
- Gas turbine control systems
- Steam turbine control systems
- Wind turbine automated assemblies
- Land-marine derivative (LM) turbine packages
- Balance of plant (BOP) control loops
- Mark VIe distributed control system (DCS) modules
FAQ
Q: Can this board run in a triple-redundant setup?
A: Yes. The controller supports simplex, dual, and triple-redundant systems. In TMR mode, the board shares voted inputs and internal state values between controllers over the VME bus.
Q: Does the 12-month warranty cover conformal coating damage?
A: The 12-month warranty covers defects in materials and workmanship. Physical damage, liquid ingress, or improper power feed voids coverage. We test each unit before it ships.
Q: How fast will my order ship?
A: In-stock units leave our warehouse in 12–24 hours. We ship by FedEx, UPS, or DHL with tracking. Share your account or let us quote freight.
Q: Will my existing ControlST project run on this revision?
A: It usually does. Match the ControlST version and firmware level to your plant. Before you buy, send us your project revision and we will confirm fit.
Q: What should I check first if the board will not boot?
A: Check 200–250 Vac input, then the cooling fan and VDSK board. Look at the 5 faceplate LEDs. A dead CMOS battery can also cause boot faults. Swap the battery and retest.
Purchase Guidance
- Confirm your rack type before ordering: GE Fanuc, short Mark VIe, or long Mark VIe
- Note your ControlST and firmware versions so we can verify match
- Order the VDSK board too if you run a standalone GE Fanuc rack
- Plan for redundancy level (simplex, dual, TMR) to get the right quantity
- Ask for a tested, revision-A unit with photos before shipment
