Selection Guide
Use the following criteria to determine the correct module for your application:
- Step 1 — Identify your system: Confirm your turbine control system is GE Mark IV Speedtronic
- Step 2 — Check the revision: Locate the existing board’s revision suffix (e.g., 1C1B vs. 1D1B) from the panel drawing or existing hardware label
- Step 3 — Verify slot assignment: Confirm the board’s designated slot in the Mark IV backplane layout drawing
- Step 4 — Assess condition requirement: Choose New OEM, Certified Refurbished, or Tested Used based on budget and criticality
- Step 5 — Contact Konmask: Share your system serial number and panel drawing number for final confirmation before ordering

Replacement & Compatibility FAQ
Q: Can DS3800NGDD1C1A replace DS3800NGDD1C1B?
A: In most Mark IV configurations, yes. The revision suffix difference (1C1A vs. 1C1B) typically reflects minor component changes. Verify with your panel drawing before installation.
Q: Is DS3800NGDD1C1B compatible with Mark V or Mark VI systems?
A: It is designed for Mark IV. Use in Mark V requires engineering review; Mark VI requires a full hardware migration to the IS200 series.
Q: Do you offer repair services for DS3800NGDD1C1B?
A: Yes. Contact us with your board condition and fault description for a repair assessment and quotation.
Q: What is the lead time for a new DS3800NGDD1C1B?
A: Stock availability varies. Contact us for real-time inventory status and expedited options for plant outage situations.
Q: Can I return a module if it is not compatible?
A: Please contact our team before ordering to confirm compatibility. Returns are handled per our standard policy — see our Returns page for details.
