Product Introduction
GE DS200TCTGG1AFF is a trip terminal board for the GE Speedtronic Mark V control system family. It belongs to the TCTG board family and serves as a trip signal interface within the turbine protection architecture.
The TCTG board is part of the Mark V protection core and is used to receive, route, or distribute trip signals between the protection logic and downstream trip circuits. It works in coordination with other Mark V boards such as TCEA, TCEB, and PTBA to execute turbine trip functions.
Based on the DS200TCTGG1A family, the board is equipped with jumpers, switch blocks, a 40-pin connector, and an LED indicator. The LED provides visual status indication for board health and trip signal processing. However, public documentation for the exact DS200TCTGG1AFF suffix is limited, so the detailed jumper count, switch block configuration, connector pinout, and trip channel assignments should be verified from the physical board label and GE Mark V manuals.
Some third-party listings describe DS200TCTGG1AFF as a PACSystems RX3i controller module with an Intel Atom processor and DDR2 memory. That description is incorrect and conflicts with the Mark V TCTG terminal board definition. It should not be treated as authoritative without verification against the physical board label and GE documentation.

Note: The TCTG trip terminal function, 40-pin connector, LED indicator, jumpers, and switch blocks are documented for the DS200TCTGG1A family. The exact jumper map, switch block count, LED assignment, connector pinout, and AFF-specific configuration should be verified from the physical board label and GE Mark V manuals.
Quality Control Process (DYNAMIC GENERATION)
- Visual and label inspection. We check the part number, suffix, PCB surface, connectors, jumpers, switch blocks, LED, and mounting hardware for damage or corrosion.
- TCTG function verification. We confirm the board matches the DS200TCTGG1AFF trip terminal board description and is not mislabeled as a PACSystems RX3i controller or other unrelated module.
- Connector and continuity check. The 40-pin connector is verified for correct pin continuity and no short circuits.
- Jumper and switch block inspection. All jumpers and switch blocks are checked for correct positioning and physical integrity.
- LED indicator check. The LED indicator is inspected for visible damage; functional testing is performed when test equipment is available.
- Final packaging. After passing inspection, the board is anti-static bagged and foam-packed for shipment.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Confirm TCTG function before installation. DS200TCTGG1AFF is a trip terminal board; do not substitute it with TCEA, TCEB, PTBA, TCQA, or other Mark V I/O boards.
❗ Ignore conflicting third-party descriptions. Some listings describe this part number as a PACSystems RX3i controller module with Intel Atom processor; that is incorrect and conflicts with the Mark V TCTG terminal board definition.
❗ Record jumper and switch block positions before removal. Document all jumper and switch block settings for correct restoration after replacement.
❗ Label all connectors before removal. Miswiring trip signal connections can cause incorrect turbine trips or failure to trip during a fault condition.
❗ Verify trip signal routing. After replacement, confirm that trip signals are correctly routed through the Mark V protection logic chain.
❗ Check LED status before removal. Document LED state for troubleshooting reference after replacement.
❗ Handle as ESD-sensitive equipment. Always use anti-static wrist straps and handling procedures during removal, installation, and storage.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
| Original Model | Replacement / Successor Model | Compatibility Level | Migration Notes |
|---|---|---|---|
| GE | GE | Direct | Same part number; verify jumper settings, switch blocks, and connector pinout. |
| GE | GE DS200TCTGG1A variants | Needs Adaptation | Same TCTG family; suffix differences may affect revision or configuration. |
| GE | GE DS200TCTGG1AEE | Needs Adaptation | Same TCTG family; verify jumper count, switch block configuration, and connector layout. |
| GE | GE DS200TCEA / DS200TCEB | Not Compatible | TCEA/TCEB are overspeed and protection expansion boards; different function. |
| GE | Mark VIe / IS200/IS220 modules | Not Compatible | Different platform and architecture; not a direct replacement. |
