System Compatibility
| Control System | Compatibility | Notes |
|---|---|---|
| GE Mark V (TCQA Panel) | ✅ Direct Fit | OEM specification |
| GE Mark V (TCDA Panel) | ⚠️ Verify Slot | Check board slot assignment |
| GE Mark VI | ❌ Not Compatible | Use IS200 series instead |
| GE Mark IV | ❌ Not Compatible | Different architecture |
| Third-party Mark V clones | ⚠️ Case-by-case | Contact support for assessment |
Selection Guide
Use the following decision flow to select the correct analog I/O board for your Mark V system:
- Step 1 — Identify your panel type: Locate the panel designation on your Mark V cabinet (TCQA, TCDA, TCRA, etc.)
- Step 2 — Confirm board slot: Match the slot number in your system drawing to the DS200TCQAG1A position
- Step 3 — Check revision level: G1A vs G1B vs G2A may differ in analog channel count or resolution — verify against your system BOM
- Step 4 — Assess condition requirement: New OEM for critical safety loops; tested refurbished acceptable for non-critical monitoring channels
- Step 5 — Confirm lead time vs. urgency: Konmask maintains ready stock for rapid dispatch — contact us for availability confirmation

Replacement & Compatibility FAQ
Q: Can DS200TCQAG1B replace DS200TCQAG1A directly?
A: In most Mark V TCQA panel configurations, yes — the G1B is a revised version with the same form factor. However, verify the firmware revision of your Mark V controller before swapping.
Q: Is DS200TCQAG1A compatible with GE Mark VI systems?
A: No. Mark VI uses the IS200 series boards with a different backplane architecture. Use IS200TCQAG1A or equivalent IS200-series parts for Mark VI.
Q: What is the difference between DS200TCQAG1A and DS200TCDAG1A?
A: Both are analog I/O boards within the Mark V DS200 family, but they belong to different sub-panel series (TCQA vs. TCDA). They are not interchangeable without verifying slot assignments and system wiring diagrams.
Q: Can I use a refurbished DS200TCQAG1A in a safety-critical loop?
A: Refurbished units that have passed full functional testing are suitable for many applications. For SIL-rated or primary protection loops, consult your system integrator and review GE’s maintenance guidelines.
Q: How do I verify the board revision before ordering?
A: The revision suffix (G1A, G1B, G2A) is printed on the board label. Share a photo of your existing board or your system BOM with Konmask support for confirmation before purchase.
Q: What is the lead time for DS200TCQAG1A?
A: Konmask maintains stock of common Mark V boards. Contact us to confirm current availability — in-stock orders typically ship within 1–3 business days.
