Functional Description

DS200SIOBH1A is an I/O control board developed by GE. It is a part of Mark V control system. It provides a range of features that enable it to control various input/output functions. The board is designed to work in conjunction with other components in the control system, and its features are tailored to meet the needs of industrial control applications. The LED light on the board provides visual feedback on system status, such as indicating when a fault has occurred or when an input or output is active. The LED can be used to troubleshoot system issues or to monitor system performance. The 40-pin connector on the board allows for communication with other components in the system, such as the central processing unit (CPU) or other I/O modules. The connector can be linked with other connectors on the board using ribbon cables, which transmit signals between the board and other components in the drive.

Features

• The Control Board has twenty jumpers and three switch blocks, each with six switches, for a total of 18 switches. It also includes one LED light and one 40-pin connector. Some of the connectors on the board can be synced and linked using ribbon cables. The ribbon cables carry a number of small wires that carry signals from the board to other components in the drive. Other wires in the ribbon cable carry signals to the board for processing.
• It is critical that the ribbon cable remain in good condition in order for the signals to be transmitted. You must follow some guidelines to do so. If you try to pull out the ribbon cable while holding the ribbon portion of the cable, the connection between the ribbon and the plastic connector may be broken. The best method is to use one hand to firmly grip the plastic connector and pull it out of the board's connector.
• Because the signals carried by the cable can be interfered with by electrical currents, you must pay attention to how the cable is routed inside the drive. Interference can be avoided by routing the cable away from current-carrying cables. Cable routing can also obstruct proper air flow, which is critical for cooling. The components of the drive generate heat, which is carried away by air flow.

System Overview

• Turbine Control Systems have been manufactured for several decades and are widely used in both new unit and retrofit applications. The Mark V is the most recent in a line of microprocessor-based turbine control systems designed specifically for turbine control.
• The system is suitable for medium and large steam turbines, heavy duty gas turbines (single or dual shaft), and aircraft derivative gas turbines. The control system is used to control and protect the unit, along with sensors and devices mounted on the unit and its auxiliaries. The use of redundant sensors and devices for feedback, control, and protection of critical functions improves unit reliability.
• If one of the redundant devices fails, the operation is unaffected. The connection of redundant devices to the control panel, as well as their regulation by the control software, were deemed critical factors in the design . This fail-safe approach results in a highly reliable turbine control and protection system.
• This triple modular redundant (TMR) design can safely operate, control, and protect a unit in the event that one of its control processors or control processor components fails. The TMR design allows for the shutdown and repair of a single control processor without shutting down the turbine.

FREQUENTLY ASKED QUESTIONS

What is DS200SIOBH1A?
It is an I/O control board developed by GE

What are the ribbon cables used for?
The ribbon cables are used to carry signals from the Control Board to other components in the drive and from other components in the drive to the Control Board for processing. They can be synced and linked with other connectors on the board.

Why is it important to handle ribbon cables carefully?
It is important to handle ribbon cables carefully because if the ribbon portion of the cable is pulled, the connection between the ribbon and the plastic connector may be broken. The best method is to use one hand to firmly grip the plastic connector and pull it out of the board's connector.

How does the turbine control system improve unit reliability?
The turbine control system incorporates redundant sensors and devices for feedback, control, and protection of critical functions. This redundancy ensures that if one of the devices fails, the operation of the turbine remains unaffected. It enhances the overall reliability of the unit.

What are the critical factors considered in the design of the turbine control system?
The connection of redundant devices to the control panel and their regulation by the control software is deemed critical factors in the design of the turbine control system. These factors contribute to the fail-safe approach and the high reliability of the system.
