DS200TCDAH1B GE Module Parts Digital I/O Board – Mark V Turbine Control System
The GE DS200TCDAH1B is a Digital I/O (TCDA) Board designed for the GE Speedtronic Mark V turbine control system. It processes digital contact input signals received from terminal boards and manages contact output signals exchanged with relay boards.
The board plays an important role in the Mark V control architecture by conditioning digital input signals, recording changes of state, and transmitting I/O information through the IONET communication network. It is used in turbine control installations where reliable signal acquisition and output coordination are essential.

The DS200TCDAH1B receives digital contact input signals from the DS200DTBA and DS200DTBB terminal boards through its JQ and JR connectors. It conditions these signals before transmitting them to the control system.
The board transfers contact output commands to associated DS200TCRA relay boards through the JO1 and JO2 connectors. These signals support relay and solenoid control within the turbine control system.
The TCDA board exchanges processed I/O information through the IONET communication network. The JX1 and JX2 connectors provide the network signal connections.
The board detects changes in contact input states and time-tags changes before forwarding the information through IONET.
The DS200TCDAH1B is a Digital I/O Board used in the GE Speedtronic Mark V turbine control system.
TCDA is the functional acronym for the Digital I/O Board in the Mark V system.
It receives contact input signals from the DS200DTBA and DS200DTBB terminal boards and transfers contact output signals to associated DS200TCRA relay boards.
JQ connects to the DTBA terminal board, while JR connects to the DTBB terminal board. Both carry contact input signals.
