Functional Description

DS200TCDAG1ACA is a digital I/O board developed by GE. It is a part of the Mark V control system. The Digital I/O Board is positioned within the digital I/O cores Q11 and Q51, plays a role in managing and processing digital contact input signals originating from the DTBA and DTBB terminal boards. Additionally, it handles the control of contact output signals, which typically involve relays or solenoids, from the two TCRA boards.

Features

• These signals, both input and output, are crucial for various operational functions within the system. Input signals from DTBA and DTBB provide essential data regarding the status of digital contacts, such as whether they are open or closed. These inputs are processed by TCDA to interpret and utilize this information for further system operations or control logic.
• It governs the transmission of output signals, which involve the activation or deactivation of relays or solenoids controlled by the TCRA boards. These outputs are significant as they directly influence the operation of connected devices or components in the broader system.
• The communication of these signals occurs over the IONET network, a dedicated communication pathway designed to ensure reliable and efficient data transfer between various components within the system architecture. Specifically, signals from TCDA are transmitted over the IONET to interact with other boards and terminal units critical to system functionality.

Connectors

• JP: Distributes power from the TCPS board located in the R1 and R5 cores to the Q11 and Q51 cores respectively. This connector ensures that adequate power is supplied to the TCDA board, enabling it to operate effectively and reliably within its designated core locations.
• JQ: Connects to the JQR socket on the DTBA board, serving as the conduit for contact input signals from the DTBA board to the TCDA board. These signals convey critical information about the status of digital contacts, such as whether they are open or closed, allowing TCDA to process and utilize this data for operational control.
• JR: Links to the JRR socket on the DTBB board, transmitting contact input signals from the DTBB board to the TCDA board. Similar to JQ, this connector facilitates the flow of digital contact status information, ensuring comprehensive monitoring and control capabilities within the system.
• JO1 and JO2: These connectors are dedicated to writing contact output signals, typically involving relays or solenoids, to the TCRA boards located in specific core locations. JO1 primarily interfaces with the TCRA board in location four of the Q11 core, while JO2 serves both the Q11 and Q51 cores, specifically targeting the TCRA board in location five. These outputs enable TCDA to actively control and operate connected devices or components as dictated by system requirements.
• JX1 and JX2: These connectors utilize shielded twisted pairs to transmit IONET signals, ensuring reliable communication within the system. In the Q11 core, JX1 transfers signals to the JX2 connection on the TCEA board located in location five of the P1 core. In the Q51 core, JX2 facilitates signal transmission to the JX connection on the CTBA terminal board situated in the R5 core. Both JX1 and JX2 serve the same function, providing flexibility in signal routing depending on system configuration and operational needs.

Frequently Asked Questions

What is DS200TCDAG1ACA?
It is a digital I/O board developed by GE under the Mark V series.

How are contact signal inversions managed on the board?
Contact signal inversions, where necessary, are implemented through software using I/O configuration constants. These constants define how input signals should be interpreted or inverted based on system requirements. This software-based approach offers flexibility in adapting to various operational scenarios without requiring hardware modifications.

What are the benefits of using IONET for signal transmission?
Transmitting signals via the IONET network, facilitated by the JX1 (or JX2) connector, ensures robust and efficient communication across different components within the system architecture. This network-based approach supports seamless integration, real-time data exchange, and enhanced reliability in transmitting processed contact inputs to other system modules or control units.

How does the board contribute to system reliability and efficiency?
By effectively processing, conditioning, and time tagging contact inputs from DTBA and DTBB boards, the board enhances overall system reliability. It ensures accurate data acquisition and transmission, minimizes signal errors, and supports timely responses to operational changes or faults, thereby optimizing system efficiency and performance.
