Product Overview
IS415UCVGH1A with part identifier V7666-111000 is a 6U VMEbus single-board UCVG (Universal Controller Video Graphics) controller card designed for GE Speedtronic Mark VI and Mark VIe turbine control systems. It is a core computing unit responsible for executing real-time turbine control algorithms, communicating with I/O packs, and connecting to HMI workstations via Ethernet.
This board adopts Intel Ultra Low Voltage Celeron 650MHz processor, equipped with 128MB SDRAM and 128MB CompactFlash storage, running QNX real-time operating system to guarantee deterministic control cycles for gas and steam turbines. It integrates dual 10/100BaseTX Ethernet ports, serial RS232 diagnostic port, VGA video output and PS/2 interface for local maintenance. It communicates to the rest of the rack through VME backplane, coordinating I/O modules, collecting field signals and issuing control commands. The rugged PCB with reinforced heat sink is built to endure vibration, EMI and temperature variation inside power plant control cabinets.
