Description
The GE DS200TCRAG1A DS200TCRAG1ACC is a TCRA Relay Output Board used in the GE SPEEDTRONIC Mark V LM turbine control system. It provides relay-based output switching for control signals within the Mark V digital I/O architecture and interfaces with associated terminal boards for field output connections.
The standard TCRA configuration can contain up to 30 relays, designated K1 through K30. Relay commands are supplied from associated Mark V control boards, while the relay outputs are routed through the board connectors to compatible DTBC or DTBD terminal boards. Certain Mark V core positions use application-specific relay configurations, so the installed system configuration should be checked before replacement.

⚙️ Application
The DS200TCRAG1A is installed within the digital I/O portion of the Mark V LM turbine control architecture. A standard TCRA board provides relay outputs that can be used for turbine control functions, solenoid control, and other commanded discrete-output applications depending on the system configuration.
Typical applications include:
- GE Mark V turbine control maintenance
- Relay output replacement
- Digital I/O system servicing
- Solenoid and discrete-control output circuits
- Gas and steam turbine control systems
- Mark V LM retrofit and spare-parts inventory
The board communicates with associated control and terminal hardware rather than operating as a standalone controller. Output configuration can depend on the specific Mark V core and terminal-board arrangement. In particular, certain relay positions may have specialized functions, so the existing board position and system drawings should be checked before installation.
⚠️ Replacement Note: Match both DS200TCRAG1A and DS200TCRAG1ACC when sourcing a replacement. The suffix identifies the specific board revision/configuration. Verify the PCB revision, board position, connector arrangement, terminal-board type, and existing system wiring before commissioning.
