Features:
- Provides the TCPA processor function in large steam-turbine Mark V panels.
- Appears at internal socket address 14 in the control-processor I/O status list.
- Uses an independent 125 VDC feed that permits board-level reinitialization.
DS200TCPAG1A belongs to the processor hardware used where the Mark V panel includes a PLU core.
A warm reset of the associated DCC does not initialize TCPA after new I/O configuration constants are downloaded.
The processor I/O status can be reviewed through the DCC Monitor, while the J7 harness provides the board's power-reset point.
GE no longer produces Mark V hardware; Apter Power may still coordinate DS200TCPAG1A support.

TCPA Control Role
- Board Function: TCPA is the turbine control processor board in the Mark V architecture.
- Panel Class: The function is associated with large steam-turbine control panels.
- System Family: The board belongs to SPEEDTRONIC Mark V.
- Card Identity: The processor status list reports the board name as TCPA.
Independent Initialization
- Download Event: New TCPA I/O constants require the processor board to be reinitialized.
- Warm Reset Limit: Resetting the associated DCC does not reboot TCPA.
- Panel Switch: The control processor's 125 VDC switch can interrupt the TCPA supply.
- Board Harness: J7 provides the board-level 125 VDC power-reset point.
I/O Monitor Review
- Display Tool: The DCC Monitor shows individual processor I/O-card status.
- Name Validation: TCPA should appear with a readable card name rather than random characters.
- Communication Fault: An invalid name can indicate that the DCC processor cannot access the card.
- Internal Address: TCPA is listed at socket 14 in the I/O-state sequence.
Steam-System Context
- Core: The TCPA card is installed in the PLU core.
- Deployment: This processor function is typically limited to larger steam-turbine panels.
- Power Domain: Its operating supply is 125 VDC.
- Reset Boundary: TCPA initialization remains separate from an ordinary DCC warm reboot.
