Core Function

UCVG VME single‑board controller for Mark VI turbine control system. It runs QNX real‑time operating system to execute turbine control logic, sequence program, protection interlock and PID closed‑loop calculation. It exchanges high‑speed data with each VME I/O board via VME64 backplane bus, collects field process signals and outputs control instructions. Dual independent Ethernet ports support EGD, Modbus TCP communication, connecting HMI, SCADA and ToolboxST engineering workstation. Reserved PMC expansion slot meets extended communication function demands. It supports simplex and TMR triple‑modular redundant architecture, undertakes core computing tasks of turbine speed regulation, load control and generator excitation adjustment, ensures stable deterministic real‑time control for power generation units.

Product Details

IS215UCVGH1A (VMIVME‑7666) belongs to UCVG series embedded VME controller hardware of GE Speedtronic Mark VI control system.

This single‑slot industrial SBC adopts Intel ultra‑low‑voltage Celeron 650 MHz processor. On‑board SDRAM and CompactFlash store firmware, application control logic and event fault log. Rich front‑panel interfaces realize network communication, serial debugging, local display and peripheral connection. VME64 backplane bus completes high‑speed data interaction with all functional I/O boards inside rack. Hardware self‑diagnosis continuously monitors module running status and uploads fault information to ToolboxST software. Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to harsh working environment of power‑plant turbine cabinet. Widely deployed in gas‑steam turbine and generator excitation control cabinets for unit core control operation.

It belongs to critical main‑controller spare‑part for Mark VI control system, widely used in overhaul and renovation projects of power generation units. It is important spare hardware for control logic debugging and defective IS215UCVGH1A module replacement.
