New-Surplus DS200TCTSG1AEE Trip Board, Factory Packaged

This DS200TCTSG1AEE is a new-surplus GE SPEEDTRONIC Mark V Simplex Trip Board supplied in its original factory packaging — the condition most maintenance teams want for a protection-critical spare that may sit on the shelf for years before it is needed. It is the TCTS card of the DS200 hardware family, revision G1AEE, and it is a like-for-like fit for panels already running that revision.

Because a trip board is only ever noticed when something goes wrong, a sealed, warranty-backed spare on the shelf is the difference between a planned relay swap and an extended forced outage.

What the Simplex Trip Board Does in a Mark V Panel

The TCTS is the relay-output stage of the Mark V trip system. It holds twelve plug-in relays (K1–K12) whose contacts are wired into the turbine's emergency-shutdown circuit, and it connects back to the control section through ribbon cables at JDR, JDS, JDT (16-pin) and JN, JM (12-pin). In the wider panel it works alongside the control cores <R>, <S> and <T>, the common core <C>, and the independent protection core <P>. The precise trip logic, setpoints and any test sequence live in the GE documentation (GEH-5980 and your unit's elementary drawings) and your site procedure — this listing stays at the identification and troubleshooting level for safety. A wider orientation is in GE Mark V DS200 Boards Explained.

Symptoms That Point Here — and the Ones That Do Not

Before you fit even a factory-sealed replacement, make sure the trip board is the actual defect. The following all look like a bad TCTS but usually are not:

• A genuine, commanded trip. If the <I> event log shows the control or protection software asked for the shutdown, the board did its job. Chase the initiating signal, not the card.
• One misbehaving relay. A single K-relay that sticks or chatters mimics a whole-board failure. The relays are pluggable, so reseat or replace the individual device first.
• Field devices. Trip solenoids, dump valves and their wiring see real duty and fail more often than the PCB itself.
• Loose or dirty connections. A partially seated JDR/JDS/JDT or JN/JM ribbon, or a fault on the relay terminal board, can drop or hold a trip channel.

When those are cleared and the board is confirmed at fault, a new-surplus unit like this one restores the panel to as-built condition.

Decoding DS200TCTSG1AEE

DS200 = Mark V DS200 board series; TCTS = Simplex Trip function; G1 = functional group; A = functional revision; EE = board/artwork hardware revision. Keep the whole string together when you specify a replacement, since group and revision differences can affect fit and function. The full method is in the GE Speedtronic Part Number Decoder.

Boards Often Ordered Alongside It

Sites refreshing trip-system spares frequently pair the TCTS with the DS200TCTG trip board, the DS200TCTE trip module and the relevant relay terminal board. If a control-system upgrade is on the horizon, Mark V vs Mark VI: DS200 to IS200 covers how the trip and I/O functions map onto the newer IS200 hardware.
