Functional Description

DS200TCDAG1AEA is a Digital I/O Board developed by GE. It is a part of the Mark V control system.The Digital I/O Board, located in the digital I/O cores Q11 and Q51, processes the digital contact input signals from the DTBA and DTBB terminal boards and the contact output (relay/solenoid) signals from the two TCRA boards. The signals are transmitted over the IONET to the TCQC board in R1 and the CTBA terminal board in R5.

Connectors

• JP: Distributes power from the TCPS board in the R1 and R5 cores to the Q11 and Q51 cores, respectively.
• JQ: Connects to the JQR socket on the DTBA board, carrying the contact input signals from the DTBA board.
• JR: Connects to the JRR socket on the DTBB board, carrying the contact input signals from the DTBB board.
• JO1: Writes the contact output (relay/solenoid) signals to the TCRA board in location four. This connector is generally not used in the Q11 core.
• JO2: Writes the contact output (relay/solenoid) signals to the TCRA board in location five. This connector is generally used in both the Q11 and Q51 cores.
• JX1: This is a shielded twisted pair for the IONET signals. The TCDA board in the Q11 core writes the signals to the JX2 connection on the TCEA board in location five of the P1 core. The board in the Q51 core writes the signals to the JX connection on the CTBA terminal board in the R5 core.
• JX2: Used for the same function as JX1. Either JX1 or JX2 can be used.

Contact Input Circuits

The board is an essential component in signal processing, particularly in handling contact inputs from the DTBA and DTBB terminal boards. These inputs are received through the JR and JQ connectors. Here’s a detailed look at how the board processes these signals:

• Signal Conditioning: Once the signals are received, the board conditions them to ensure they are suitable for further processing. This step may involve filtering, amplifying, or converting the signals to the required format.
• Time Tagging: The board assigns precise time tags to any change in state of the input signals. This time-stamping is crucial for accurate monitoring and recording of events.
• Signal Transmission: After conditioning and time tagging, the signals are transmitted to the IONET (Input/Output Network). This is achieved through the JX1 or JX2 connector, depending on the specific configuration.
• Software-based Signal Inversion: The board allows for signal inversions for the contact inputs. This inversion is managed through software, using I/O configuration constants. This flexibility ensures that the system can accommodate various signal requirements and configurations.

Contact Output Circuits

In addition to processing input signals, the board also manages contact output signals. Here’s how it handles these outputs:

• Output Transmission: The contact outputs are transmitted from the TCDA board to the TCRA boards. This transmission occurs via the JO1 and JO2 connectors.
• Relay/Solenoid Activation: These contact outputs typically control relays or solenoids, which are critical components in various mechanical and electrical systems. The precise control and timing provided by the board ensure reliable operation of these components.
