๐น Product Overview
The GE IS200VTURH2BAC is a Turbine Control / Protection I/O Board designed for the GE Mark VI Speedtronic turbine control platform. The board is associated with the VTUR turbine protection function and is used to acquire and process critical turbine operating signals for monitoring and protection.
The VTUR board works as part of the larger Mark VI control architecture rather than as a standalone controller. Depending on the turbine configuration, it can be involved in monitoring turbine speed, protection signals, flame detection and other turbine-related inputs. Its VME-style board design allows it to integrate into the corresponding GE control rack and communicate with the rest of the control system.
For maintenance work, the exact board revision and cabinet configuration should be checked before replacement. The IS200VTURH2BAC is also referenced as IS200VTURH2B in some supplier documentation, so matching the complete board identification on the PCB is recommended.

โ๏ธ Main Functions
- Turbine protection signal acquisition
- Turbine speed and rotating-equipment signal monitoring
- Interface with turbine protection circuitry
- Processing of selected field sensor inputs
- Support for overspeed protection functions
- Flame detection interface in applicable configurations
- Integration with the GE Mark VI turbine control architecture
- High-speed signal exchange with the turbine control system
Some technical sources specifically describe the board as supporting multiple speed-probe inputs and turbine protection functions. The actual I/O assignment depends on the Mark VI cabinet and turbine application configuration.
๐ญ Typical Applications
The IS200VTURH2BAC is generally associated with GE turbine control installations such as:
- Gas turbine generator systems
- Steam turbine control systems
- Power generation plants
- Industrial turbine packages
- Turbine speed and overspeed protection
- Turbine flame detection and protection systems
- Mark VI turbine control cabinets
- Industrial and marine turbine applications where a compatible GE Mark VI configuration is installed
The board is part of the turbine protection architecture, so replacement should be based on the complete system configuration rather than model number alone.
๐ง Installation & Replacement Notes
Before installing a replacement board, technicians should compare:
- Complete board part number: IS200VTURH2BAC
- PCB revision and hardware build
- Existing VTUR board configuration
- Mark VI rack and slot position
- Field wiring and connector condition
- Existing software/firmware configuration
- Turbine-specific protection logic
- Sensor input assignments
The board should be handled using appropriate ESD precautions. Edge connectors, terminal connections and the PCB surface should be inspected before installation.
After installation, the control system should be checked for diagnostic alarms and communication faults. Turbine protection functions and field signal readings should be verified according to the plant’s commissioning or maintenance procedure before returning the turbine to normal operation.
๐ Identification References
When purchasing a replacement, the following markings may help identify the correct board:
- IS200VTURH2BAC
- IS200VTURH2B
- VTUR H2B
- S2CF0D5
- MRP 956161
- FA/00
- 44S770233-001A
- U524 9A9F
- 9322037-01 A
- L-442333 ET
- 420625
- 9320948
These references appear in supplier and resale documentation associated with the board. They should be used for identification, while the physical PCB marking remains the final reference for a replacement check.
โ Frequently Asked Questions
Q: What system does the IS200VTURH2BAC belong to?
A: It belongs to GE’s Mark VI Speedtronic turbine control system family and is associated with the VTUR turbine protection function.
Q: Is IS200VTURH2BAC the same as IS200VTURH2B?
A: IS200VTURH2B is commonly used as a related identification for this board, but buyers should compare the complete PCB part number, revision and cabinet configuration before treating them as interchangeable.
Q: What does VTUR stand for?
A: VTUR is the functional designation used for the turbine protection board within the GE Mark VI architecture.
Q: Can this board be used as a universal turbine controller?
A: No. It is a specialized board intended to operate within the GE Mark VI control architecture. It should not be treated as a standalone PLC or universal turbine controller.
Q: What should be checked before ordering?
A: Confirm the complete part number, revision, existing board markings, cabinet configuration and turbine control system. For a critical protection application, matching the original hardware configuration is particularly important.

๐ ๏ธ Maintenance Recommendations
For a VTUR board kept as a critical spare, store it in an ESD-safe package and avoid unnecessary exposure to humidity, dust and conductive contamination.
During incoming inspection, check the PCB for cracked components, damaged connectors, corrosion, burned areas and signs of previous repair. Compare all board labels and revision markings with the installed unit.
For used equipment, functional testing in an appropriate GE Mark VI test environment is preferable before installation into a live turbine control cabinet. The referenced eBay listing identifies this particular unit as Used, so its actual condition should be confirmed from the physical board and seller inspection record before purchase.
๐ Ordering Information
Please provide the complete GE part number IS200VTURH2BAC, along with photos of the board label if available. For replacement projects, also provide the original board revision and cabinet/system information. This helps avoid confusion between VTUR, TTUR, PTUR and other Mark VI turbine-control boards.
