The DS200TCCAG1AJB is a TCCA Common Analog I/O Board for the GE Speedtronic Mark V turbine control platform. Installed in the <R5> core, it scales and conditions analog signals arriving from the CTBA, TBQA and TBCA terminal boards.
The handled signal groups include 4-20 mA inputs and outputs, resistance temperature detectors, thermocouples, shaft voltage and shaft current. Conditioned values are transferred toward the STCA board through the 3PL data path for use by the control system.
TCCA
Common analog processing between field termination and the Mark V control data path.

Revision control: DS200TCCAG1AJB includes a specific group and revision suffix. Match the complete installed part number, connector arrangement, firmware context and site configuration before substitution. Field signal configuration for thermocouples, RTDs, milliamp I/O and shaft monitoring is established within the Mark V I/O configuration environment.
Features & Applications
Multi-signal conditioning Supports the common temperature, current and shaft-monitoring signal groups used by Mark V turbine controls.
Structured terminal interface Dedicated connectors organize signal paths between field termination boards and the analog processing core.
Control-system diagnostics TCPS diagnostic signals reach the board through JC, supporting the core-level monitoring arrangement.
Turbine control service Applied in installed Mark V gas and steam turbine control cabinets for maintenance, life extension and spare-board planning.

What does this board do in Mark V? It conditions common analog signals from the CTBA, TBQA and TBCA terminal boards and transfers conditioned values through the <R5> core data path.
02
Can another DS200TCCA revision replace G1AJB? Do not select a substitute by family prefix alone. Confirm the full suffix, installed connector arrangement, board revision and site configuration before ordering.
03
Which signal types are associated with the board? The TCCA function covers 4-20 mA I/O, RTDs, thermocouples, shaft voltage and shaft current signals.
04
What should be supplied with a quotation request? Provide the full part number, visible board revision, connector photos, required condition, quantity and delivery destination.
05
Is configuration required after replacement? Hardware jumper positions and Mark V I/O configuration must correspond to the installed application. Replacement work should be completed by qualified turbine-control personnel.
