IS215UCVDH9A is a Double-Slot Controller Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Gas Turbine Control Systems. The UCVD is a double-slot board using a 300 MHz AMD K6 processor with 8 MB of flash memory and 16 MB of DRAM. A single 10BaseT (RJ-45 connector) Ethernet port provides connectivity to the UDH. The UCVD contains a double column of eight status LEDs. These LEDs are sequentially turned on in a rotating pattern when the controller is operating normally. When an error condition occurs, the LEDs display a flashing error code that identifies the problem.


  • Redundancy and Fault Tolerance: Double-slot controller boards in turbine control systems often incorporate redundancy features to ensure continuous operation even in the event of hardware failures. This includes redundant power supplies, dual processors, and duplicated critical components to minimize downtime and maintain system reliability.
  • High-Speed Data Processing: Turbine control systems require rapid processing of large volumes of data to accurately monitor and regulate turbine operation. Double-slot controller boards are equipped with high-performance processors and data processing capabilities to handle real-time data acquisition, analysis, and control algorithms effectively.
  • Wide Range of I/O Interfaces: Turbine control systems interface with various sensors, actuators, and monitoring devices. Double-slot controller boards provide a comprehensive range of I/O interfaces, including analog inputs and outputs, digital inputs and outputs, thermocouple inputs, and serial communication ports (such as RS-232, RS-485, or Modbus) to facilitate seamless integration with different components of the turbine system.
  • Embedded Safety Features: Safety is paramount in turbine control systems to prevent accidents and protect equipment. Double-slot controller boards incorporate embedded safety features such as hardware watchdog timers, redundant sensor inputs, and built-in diagnostics to ensure the safe and reliable operation of the turbine under all conditions.
  • Customizable Control Algorithms: Turbines operate under diverse operating conditions and performance requirements. Double-slot controller boards support customizable control algorithms that can be tailored to specific turbine models, environmental conditions, and operational objectives to optimize performance, efficiency, and reliability.
  • Real-Time Monitoring and Reporting: Double-slot controller boards feature real-time monitoring capabilities to continuously assess turbine health, performance, and operational parameters. They provide comprehensive data logging, trending, and reporting functionalities to facilitate predictive maintenance, troubleshooting, and performance optimization.
  • Integration with SCADA Systems: Turbine control systems are often integrated into supervisory control and data acquisition (SCADA) systems for centralized monitoring and control. Double-slot controller boards support communication protocols such as Modbus, DNP3, OPC-UA, or Ethernet/IP to seamlessly integrate with SCADA systems and enable remote monitoring and control capabilities.
