Selection Guide
Use the following criteria to confirm the correct part for your application:
- Step 1 — Identify your control system: Confirm Mark IV vs. Mark V vs. Mark VI. Each generation uses different board revisions.
- Step 2 — Check hardware revision: The suffix (1A1A, 1B1B, 1C1C) indicates PCB revision. Match to your existing rack documentation.
- Step 3 — Verify slot assignment: Ground detector boards occupy a dedicated slot in the Mark IV I/O rack. Confirm slot number from your panel drawing.
- Step 4 — Assess condition requirement: For critical protection circuits, new or factory-refurbished units are recommended over tested-used.
- Step 5 — Contact Konmask for cross-reference: If your part number differs slightly, send us your panel drawing or nameplate photo for verification.

Replacement & Compatibility FAQ
Q: Can DS3800NGDC1B1B replace DS3800NGDC1A1A directly?
A: In most Mark IV racks, yes — the 1B1B revision is backward-compatible. However, verify with your GE panel drawing before installation.
Q: Is this board compatible with Mark VI systems?
A: No. Mark VI uses the IS200-series boards. The DS3800NGDC1A1A is specific to Mark IV architecture.
Q: Do you provide a warranty?
A: Yes. New units carry manufacturer warranty. Refurbished units carry a 90-day Konmask functional warranty.
Q: Can you source this part if it’s not in stock?
A: Yes. Submit an RFQ and our sourcing team will locate the unit within 3–5 business days.
Q: What information do I need to provide for a cross-reference check?
A: Part number, hardware revision suffix, control system generation (Mark IV/V/VI), and panel drawing number if available.
