Original GE UCVG VME single‑board controller for Mark VIe turbine control system.

Product Overview

IS415UCVGH1A (V7666‑111000) is UCVG universal control processor board for GE Speedtronic Mark VIe platform. Equipped with embedded real‑time processor, it executes turbine control algorithm logic, IONet communication scheduling, alarm processing and HMI data interaction. Runs QNX real‑time operating system, supports SIL3 safety requirement and simplex/dual/TMR redundant configuration. Conformal‑coated PCB adapts to continuous operation in power‑plant cabinet. Widely used as maintenance spare part for gas‑steam turbine and generator control systems.
