Compatible Replacement & Equivalent Models
When the IS200TSVOH1B is unavailable or end-of-life, the following models may serve as direct or functional replacements depending on your system revision and I/O pack configuration. Always verify firmware and hardware revision compatibility before substitution.
- IS200TSVOH1A — Earlier hardware revision; functionally equivalent in most Mark VI configurations
- IS200TSVOH1C — Later revision with minor PCB updates; drop-in compatible in most cases
- IS200TSVOH2A / H2B — Alternate channel-count variant; verify servo loop count before substituting
- IS215TSVOH1A — Mark VIe series equivalent; requires Mark VIe I/O pack (VSVO or PSVO)
- Third-party compatible boards — Available from certified aftermarket suppliers; must meet GE servo signal specifications
Note: Konmask.com recommends consulting your GE Mark VI system documentation or contacting our technical team before substituting any servo termination board.
Why Choose the Original IS200TSVOH1B
- OEM-certified design — Engineered and validated by General Electric for Mark VI servo control loops
- Proven field reliability — Deployed in thousands of gas turbine, steam turbine, and combined-cycle power plants globally
- Exact signal compatibility — Eliminates integration risk associated with aftermarket or cross-brand substitutes
- Warranty & traceability — Sourced units from Konmask.com include full traceability documentation
- Reduced commissioning time — Plug-and-play replacement within existing Mark VI cabinet wiring
Typical Applications
- Gas turbine fuel control servo loops (GE Frame 5, 6, 7, 9 series)
- Steam turbine governor valve and intercept valve servo control
- Combined-cycle power plant turbine control upgrades
- Compressor anti-surge control systems using Mark VI
- Retrofit and life-extension projects replacing older Mark IV / Mark V systems
- Spare parts inventory for critical power generation assets
System Compatibility
- Primary System: GE Mark VI Turbine Control System
- Compatible I/O Packs: VSVO (Servo I/O Pack), PSVO (Protection Servo I/O Pack)
- Controller Compatibility: Mark VI UCSC, UCVG, UCVE controllers
- Toolchain: GE ToolboxST configuration software
- Not compatible with: Mark V (IS200 series boards are Mark VI-specific); verify before ordering for Mark VIe without adapter
Selection Guide
Use the following criteria to confirm the IS200TSVOH1B is the correct board for your application:
- Step 1 — Identify your control system: Confirm you are running GE Mark VI (not Mark V or Mark VIe)
- Step 2 — Check hardware revision: Match the H1B revision to your existing cabinet documentation or GE BOM
- Step 3 — Count servo channels: Verify the number of servo valve outputs required matches the TSVO board channel count
- Step 4 — Confirm I/O pack pairing: Ensure your VSVO or PSVO I/O pack is compatible with the H1B revision
- Step 5 — Review firmware: Check ToolboxST configuration for any board-specific firmware dependencies

Replacement & Compatibility FAQ
Q: Can I use IS200TSVOH1A instead of IS200TSVOH1B?
A: In most Mark VI configurations, yes. The H1A and H1B are minor hardware revisions. Verify your ToolboxST configuration does not reference a board-specific parameter tied to the H1B revision.
Q: Is IS200TSVOH1B compatible with Mark VIe?
A: Not directly. Mark VIe uses a different I/O architecture. The IS215TSVOH1A is the Mark VIe equivalent. Contact us if you are migrating from Mark VI to Mark VIe.
Q: What is the difference between TSVO and PSVO?
A: TSVO (IS200TSVOH1B) is the termination board — it provides the physical wiring interface. PSVO/VSVO are the I/O packs that plug into the termination board and communicate with the Mark VI controller.
Q: Do you offer exchange / core return programs?
A: Yes. Contact support@konmask.com to discuss exchange pricing if you have a faulty IS200TSVOH1B core to return.
Q: Can Konmask.com provide a test report?
A: Yes, functional test reports are available for refurbished units upon request at time of order.
