DS200TCDAH1BHE - Digital I/O Board

SPECIFICATIONS

Part No.: DS200TCDAH1BHE
Manufacturer: General Electric
Product Type: Digital I/O Board
Product Description: Digital I/O Board
Country of Manufacture: United States (USA)
Series: Mark V

Functional Description

DS200TCDAH1BHE is a Digital I/O Board developed by GE. It is a part of Mark V Series. The primary function of the board is to process and route digital signals. It handles input signals from the DTBA and DTBB terminal boards, which are responsible for managing contact inputs. Additionally, the board processes contact output signals, which can be from relays or solenoids, coming from the TCRA boards. These signals are then transmitted over the IONET communication network to the TCQC board in R1 and R2 (if Q21 is installed) and to the CTBA terminal board in R5. This facilitates smooth data transmission and control signals across various parts of the turbine control system.

Connectors

The board is equipped with several connectors, each performing distinct functions to ensure proper operation:

• JP Connector: Distributes power from the TCPS board in the R1, R2, and R5 cores to the Q11, Q21, and Q51 cores, respectively.
• JQ Connector: Connects to the JQR socket on the DTBA board and carries contact input signals from the DTBA board to the board.
• JR Connector: Connects to the JRR socket on the DTBB board and carries contact input signals from the DTBB board to the board.
• JO1 Connector: Writes contact output (relay/solenoid) signals to the TCRA board in location four. It is not used in the Q11 core, as relays in location four are directly controlled by the TCQE board in R1.
• JO2 Connector: Writes contact output (relay/solenoid) signals to the TCRA board in location five.
• JX1 and JX2 Connectors: These shielded twisted pair connectors are used for the IONET signals. The TCDA board in the Q11 core writes signals to the JX2 connection on the TCEA board in the P1 core, while the Q51 core writes signals to the JX connection on the CTBA terminal board in the R5 core. Either JX1 or JX2 can be used for this purpose.

Hardware Configuration and Jumpers

The board includes eight hardware jumpers, which provide additional configuration and testing capabilities. These jumpers allow users to configure the board for specific system requirements or perform diagnostic tests. The functions of the jumpers are as follows:

• J1 and J8: Used for factory test purposes.
• J2 and J3: Control the IONET termination resistors to ensure proper communication on the network.
• J4, J5, and J6: Used to set the IONET ID for the board, ensuring proper identification and communication within the network.
• J7: Enables the stall timer function, which is essential for specific system control applications.

Frequently Asked Questions

What is DS200TCDAH1BHE?
It is a Digital I/O Board developed by GE.

What are the jumper settings on the board?
The board has eight jumpers that control specific functions. J1 and J8 Used for factory test. J2 and J3 Manage IONET termination resistors. J4, J5, and J6 Set the IONET ID for the board. J7 Enables the stall timer function for specific control applications.

How does the board communicate with other parts of the system?
The board communicates with other parts of the control system through the IONET network. It processes digital signals from the terminal boards (DTBA, DTBB) and sends them to the TCQC board in the R1 and R2 cores, as well as to the CTBA terminal board in the R5 core. It also transmits output signals to the TCRA boards for relay and solenoid control.

What is the role of the IONET in the board's operation?
The IONET network facilitates communication between the board and other control components within the turbine system. The board transmits and receives digital signals over the IONET network to ensure proper operation and control of various functions such as speed regulation, flame detection, and generator control.
