The GE IS415UCVHH1A is a Controller Board, a core component of GE’s Mark VIe Series Innovation Series VME platforms, designed for gas turbine control systems. As a 6U single-board computer, it operates turbine application code using QNX, a real-time multitasking OS optimized for industrial speed and reliability. Mounted on a VME rack, it connects to turbine I/O boards via the VME bus, facilitating critical control and communication functions in gas, steam, and balance-of-plant applications.
Equipped with three communication ports—Ethernet for UDH, RS-232C COM1 for setup, and COM2 for DCS communication—it enables seamless data exchange. Its high-performance processing supports up to 100,000 rungs/blocks per second, with clock synchronization to the VCMI board within ±100 microseconds.
Features:
Processing Power: 6U SBC running QNX OS, executing up to 100,000 rungs/blocks per second for real-time turbine control logic.
Versatile Connectivity: Ethernet, RS-232C COM1, and COM2 ports ensure integration with HMIs, I/O, and external systems.
Synchronization: Clocks synchronize to the VCMI board within 100 microseconds via external interrupts, critical for coordinated I/O operations.
VME Integration: Connects to I/O boards via the VME bus; works with VCMI boards for data exchange with the control system database.
Installation Flexibility: Fits three rack types with cooling fans and optional VDSK boards for fan power/rack ID.
Application Support: Runs software for gas, steam, LM, and BOP systems, processing I/O data and internal states in simplex or TMR configurations.
Industrial Reliability: Built for harsh environments, ensuring stable performance in turbine control with robust hardware and real-time OS capabilities.
