Product Introduction
GE DS200QTBAG1ACB is a Mark V relay terminal board used in GE drive and control systems. It handles R-S-T termination and field wiring interface functions in legacy industrial automation installations.
Buyers usually source this part for exact-match replacement work, not system redesign. The main value is fitment to the existing Mark V platform, but you still need to confirm suffix, terminal layout, and rack compatibility before installation.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No field signal reaching the controller | Open wiring or bad terminal landing | ✅ High | Inspect terminal screws, wire continuity, and cable shield termination | Re-terminate wiring before replacing the board |
| Relay outputs do not change state | Upstream control issue or failed terminal path | ✅ High | Measure control voltage at the board terminals with a multimeter | Confirm the drive or controller is issuing the command first |
| Intermittent faults during vibration | Loose terminal screws or cracked solder joints | ✅ Medium | Gently tug each wire and inspect for heat marks or movement | Tighten and recheck before ordering a replacement |
| Board appears dead | Missing rack power or blown upstream fuse | ✅ High | Measure supply voltage at the rack and check fuses | Verify power and fuse health before blaming the board |
| Unexpected channel mismatch | Wrong suffix or revision variant | ✅ High | Compare the installed board label to DS200QTBAG1ACB exactly | Match the full part number, not just the base model |
| One circuit works, another does not | External wiring or terminal block issue | ✅ Medium | Trace the failed circuit from the cabinet to the load | Check the harness and load side before swapping hardware |
If you are stuck, contact technical support with photos of the board, terminal strip, rack, and any fault logs.

Frequently Asked Questions
Q: What is the GE DS200QTBAG1ACB used for?
A: It is a Mark V relay terminal board used for R-S-T termination and field signal interface in GE drive systems.
Q: Is this part still in production?
A: No, this is a legacy Mark V part. Most available units come from surplus inventory or tested stock, so availability can change quickly.
Q: Can I use a DS200QTBAG1A or another suffix instead?
A: Do not assume that. The suffix matters, and the wrong revision can create wiring or compatibility problems. Match the exact part number on the existing board.
Q: Is it plug-and-play?
A: Usually it is a direct replacement only if the terminal layout, rack, and wiring match the original installation. To be honest, swapping legacy GE boards without checking the wiring map first is asking for downtime.
Q: Why is surplus cheaper than OEM factory stock?
A: Because it is typically old inventory, not current production. The price reflects availability, age, and sourcing method, not a lower electrical rating.
Q: What should I verify before ordering?
A: Confirm the full model number, suffix, terminal count, rack type, and field wiring arrangement. A quick photo of the old board can prevent a costly mismatch.
Q: Is this board refurbished or new surplus?
A: Listings are often new surplus or tested surplus. If you need refurbished, ask for the test status, cosmetic condition, and any warranty terms before purchase.
