Compatible Replacement & Equivalent Models
When the original DS3800HIOD1H1G is unavailable or cost-prohibitive, the following models may serve as functional replacements or equivalents depending on your system configuration. Always verify firmware revision and I/O channel mapping before substitution.
- DS3800HIOD1H1F — Earlier revision of the same board; functionally equivalent in most Mark IV applications
- DS3800HIOD1H1D — Compatible predecessor; verify I/O channel count matches your wiring diagram
- DS3800HIOD (base part) — Generic designation; confirm full suffix for exact hardware match
- IS200 Series I/O Boards — GE Mark VIe generation; requires system-level upgrade and is not a drop-in replacement
- Third-party compatible boards — Available from select industrial automation suppliers; must pass point-to-point I/O verification before commissioning
Note: Konmask.com recommends using OEM-original or OEM-equivalent tested boards for safety-critical turbine control applications. Contact our team for compatibility verification.
Why Choose the Original Model
- Guaranteed compatibility with GE Mark IV control architecture and existing wiring harnesses
- Validated firmware — no re-parameterization or logic re-mapping required
- Regulatory compliance — maintains OEM certification status for power generation and industrial facilities
- Reduced commissioning risk — plug-and-play replacement minimizes downtime during maintenance windows
- Long-term support — original part numbers are traceable in GE service documentation and spare parts databases
Typical Applications
- Gas turbine and steam turbine control panels (GE Frame 5, Frame 6, Frame 7 series)
- Combined-cycle power plant automation
- Industrial compressor control systems
- Turbine protection and sequencing logic
- Retrofit and upgrade projects for aging Mark IV installations
- Spare parts inventory for power generation O&M teams
System Compatibility
- Primary System: GE Mark IV Speedtronic Turbine Control
- Compatible Racks: Mark IV I/O expansion racks using standard card-edge connectors
- Signal Types: Discrete (digital) inputs and outputs; 24 VDC or 125 VDC logic levels (verify per site drawing)
- Not compatible with: Mark V, Mark VI, or Mark VIe without hardware and software adaptation
Selection Guide
Use the following criteria to determine whether the DS3800HIOD1H1G is the correct board for your application:
- Step 1 — Confirm system generation: Verify your turbine control system is GE Mark IV (Speedtronic). Check the control panel nameplate or system documentation.
- Step 2 — Match the full part number: The suffix (H1G, H1F, H1D, etc.) indicates hardware revision. Match the suffix to your existing board or consult the system BOM.
- Step 3 — Verify I/O channel count: Count the discrete input and output channels required by your wiring diagram. Confirm the replacement board supports the same channel configuration.
- Step 4 — Check firmware revision: If your system uses a specific firmware version, confirm the replacement board is compatible before installation.
- Step 5 — Assess condition requirements: For critical applications, specify new or factory-refurbished units. For non-critical spares, tested used boards may be acceptable.

Replacement & Compatibility FAQ
Q: Can DS3800HIOD1H1F replace DS3800HIOD1H1G?
A: In most Mark IV applications, yes. The H1F is an earlier hardware revision with the same functional design. Verify the I/O channel mapping and connector pinout against your site drawings before installation.
Q: Is this board compatible with GE Mark V or Mark VI systems?
A: No. The DS3800 series is specific to Mark IV architecture. Mark V uses the DS200 series, and Mark VI/VIe uses IS200/IS215 series boards.
Q: Can I use a third-party equivalent board?
A: Third-party boards may be used in non-safety-critical auxiliary applications. For primary turbine protection and sequencing, Konmask.com recommends OEM or OEM-equivalent tested boards.
Q: Do you offer repair services for faulty DS3800HIOD1H1G boards?
A: Yes. Contact us with your board’s fault description and we can arrange evaluation and repair quotation.
Q: What is the lead time for a new unit?
A: In-stock units ship within 1–3 business days. For sourced or refurbished units, typical lead time is 5–15 business days depending on availability.
