Features:
- Concentrates Mark V C-core analog input and output processing on the TCCA assembly.
- Connects CTBA and TBCA termination hardware to their assigned analog channels.
- Handles current, temperature and shaft-monitoring signal groups within one core.
The TCCA hardware forms the analog-processing layer of the C processor, bringing several measurement types into a common card definition rather than separating each signal family onto an independent controller.
DS215TCCAG1BZZ01A DS200TCCAG1BAA coordinates its external terminations with the configured C-core channels, so field wiring and software assignments remain tied to the same installed assembly.
Its DS215 assembly identifier and DS200 board identifier must be recorded together during replacement work to preserve the relationship between fitted hardware, PROM arrangement and panel records.
For legacy Mark V maintenance, General Electric DS215TCCAG1BZZ01A DS200TCCAG1BAA Common Analog I/O Board may be sourced through Apter Power for existing C-core installations.

C-Core Hardware Coordination
- Processor location: TCCA functions are assigned to the Speedtronic Mark V C processor.
- CTBA relationship: CTBA provides termination paths for analog channels processed by the TCCA card.
- TBCA relationship: TBCA is the second analog termination board connected to the same TCCA definition.
- Assembly identity: Both complete DS215 and DS200 markings must match the installed TCCA hardware set.
Internal and Field Signal Paths
- Termination links: Cables from CTBA and TBCA carry their assigned analog channels to the TCCA assembly.
- Core data path: The TCCA card exchanges its processed I/O data within the C-core electronics.
- Channel routing: Each external terminal remains associated with a defined input or output position in the unit configuration.
- Replacement continuity: Connector orientation and cable destination must be preserved when the assembly is changed.
Analog Functions Managed by TCCA
- Current inputs: Milliamp channels bring configured process measurements into the C processor.
- Temperature inputs: RTD and thermocouple channels support assigned thermal measurements.
- Shaft monitoring: Shaft voltage and shaft current signals enter through dedicated monitoring paths.
- Current outputs: Configured 4-20 mA channels transfer analog commands from the control system.
Mark V Analog-I/O Duties
- Steam-turbine control: TCCA channels collect auxiliary measurements used by Mark V steam-turbine control cores.
- Gas-turbine control: Process and temperature inputs support heavy-duty gas-turbine monitoring and regulation.
- Aeroderivative systems: Applicable Mark V panels use the C-core analog path for unit and auxiliary signals.
- Generator monitoring: Shaft voltage and current channels extend the board role beyond standard process transducers.
