DS200TCTGG1A GE Mark V

The DS200TCTGG1A is a Simplex Trip Board (abbreviated as TCTG) installed in Slot 4 of the control core rack. It is responsible for the physical execution of gas/steam turbine emergency shutdown logic, receiving trip commands from the control processor to drive external trip solenoid valves via onboard relays, cutting off fuel or steam supply to ensure safe turbine shutdown.

In terms of hardware architecture, the board is equipped with 21 plug-in electromechanical relays (numbered K1–K21), secured by metal latches to allow for quick replacement; It also features 3 50-pin connectors (JLX, JLY, JLZ) and 2 12-pin connectors (JN, JM) for signal input and output. The board is protected by a standard coating (Normal Coating) and is suitable for standard industrial control cabinet environments.

• 21 plug-in electromechanical relays (K1-K21) with metal latches for quick replacement
• Relay contacts rated at 120 VDC / 125 VDC
• Supports multiple trip trigger signals with simplified hardware jumper configuration
• Operating temperature range: -30°C to +65°C
• Hot-swapping capability for direct field replacement
• 3x 50-pin connectors (JLX, JLY, JLZ) and 2x 12-pin connectors (JN, JM)
• Standard coating protection for industrial control cabinet environments

In Mark V system trip protection chains, the DS200TCTGG1A works with complementary boards:

• DS200TCQA Board: Provides PTR trip signals and synchronization commands
• DS200TCEA Board: Manages emergency trip relays and core-level emergency action logic
• DS200TBRG Series: Receive drive signals and interface with external high-power trip relays
• DS200PTBA Board: Provides busbar and generator signals for synchronization relays

A natural gas turbine control system in Saudi Arabia experienced TCTG board failure. The customer replaced it with a DS200TCTGG1AFF board, completing installation and restoring operation within 30 minutes, demonstrating the board's plug-and-play replacement capability.
