Functional Description

IS200DSPCH1A is a Turbine Control Board developed by GE. It is a part of Mark VI control system. The Mark VI system offers two configurations- simplex control and triple modular redundant (TMR) control, available in single or multiple rack setups, along with options for local or remote I/O. The I/O interface is specifically engineered to directly connect with the turbine's sensors and actuators, eliminating the requirement for additional instrumentation. This design choice not only streamlines the integration process but also mitigates reliability and maintenance concerns typically associated with intermediary instrumentation.

Operating Conditions

• Temperature Control: The temperature within the control module, including running fans, should be maintained within the range of 0 to 60°C (32 to 140 °F). Similarly, the I/O module should operate within this temperature range. Enclosures housing these components should be designed to regulate temperatures within these acceptable limits.
• Relative Humidity: Relative humidity levels should fall between 5 to 95%, ensuring a non-condensing environment. It's crucial to avoid excessive humidity, as condensation can adversely affect electronic components.
• Factors Affecting Performance and Life: Environments containing excessive amounts of dust, dirt, or foreign matter, as well as experiencing vibration, shock, moisture, rapid temperature changes, or exposure to caustic fumes, can degrade panel performance and shorten the operational life of the components. Additionally, power line fluctuations and electromagnetic interference from various sources, such as radio frequency signals or stray high voltage, can introduce noise and disrupt system operation.
• Preferred Location and Mounting: Ideally, the Mark VI control system cabinet should be situated in an environmentally controlled room or within the control room itself. The cabinet should be securely mounted on a flat, level, and continuous surface using mounting hardware provided by the customer. Lifting lugs are provided for installation, with lifting cables not to exceed 45° from the vertical plane. Additionally, the cabinet features a lockable door handle for security purposes.
• Cable Access and Convection Cooling: Interconnecting cables can be routed into the cabinet from the top or bottom through removable access plates. It's essential to seal conduits to these access plates to maintain convection cooling within the cabinet. Any air passing through the conduit must fall within the acceptable temperature range specified earlier to prevent overheating of internal components. This requirement applies to both top and bottom access plates, ensuring efficient cooling and optimal performance of the Mark VI control system.
