TECHNICAL SPECIFICATIONS FOR GE - IS200TDBSH8A

IS200TDBSH8A is a simplex contact input/output terminal board developed by GE. It is a part of the Mark VIe control system. Within Mark VIe systems, the PDIO I/O pack collaborates seamlessly with the board. This I/O pack is effortlessly integrated via a D-type connector, establishing communication with the controller through Ethernet. A singular connection point facilitates PDIO connectivity, offering the option for one or two network connections from the PDIO to the controllers.

CONFIGURATION

Board Configuration: The board itself does not feature any jumpers or hardware settings for configuration. Instead, it serves as a versatile interface for connecting external devices and sensors to the control system, providing flexibility and scalability without the need for manual adjustments.

Option Board WROBH1 Configuration: The option board, designed to control relays, includes six jumpers that control the application or removal of power to each relay. By default, all six jumpers are installed on the board during production, ensuring that power is supplied to each relay. However, when a relay is intended for use as dry contacts without power distribution, the corresponding jumper is removed from the board.

Option Board WROFH1 Configuration: The option board, responsible for fuse monitoring and voltage sensing, does not feature any jumpers for configuration. Instead, the inclusion or exclusion of a series fuse for each relay is determined by the terminal point used as the relay common. If direct use of the fuse voltage sensing circuit as a voltage detector is desired, the associated WROF fuse may be removed for each relay.

Option Board WROGH1 Configuration: Similar to the board, the WROGH1 option board does not incorporate any jumpers for configuration purposes. Instead, the corresponding fuse for each relay may be removed if the relay is intended to provide dry contacts without power distribution. This flexibility allows for customization based on specific application requirements.

FAULT DETECTION

Separate Contact Pair: In relay position feedback, a dedicated contact pair is utilized solely to provide feedback on the relay's position or state. This contact pair is distinct from the contacts used to control the load or perform other functions.

Monitoring Relay State: The feedback contact pair is designed to change its state based on the position of the relay. For example, when the relay is in its default or resting position, the feedback contacts may be open. Conversely, when the relay is activated or energized, the feedback contacts may close.

Continuous Monitoring: The status of the feedback contacts is continuously monitored by the system's monitoring circuitry or control unit. This monitoring ensures that any changes in the relay's position are promptly detected and acted upon.

Fault Detection: If a fault occurs, such as a relay failing to energize or de-energize as expected, the feedback mechanism detects this discrepancy. For instance, if the feedback contacts do not change state as anticipated when the relay is activated, it indicates a fault in the relay's operation.

Alerting and Response: Upon detecting a fault through the relay position feedback mechanism, the system can trigger an alert or alarm to notify operators or initiate corrective actions. This proactive approach helps mitigate potential issues before they escalate and impact system performance or safety.
