Core Function

UCVH high‑performance VME single‑board controller for Mark VI turbine control system. It runs QNX real‑time operating system to execute complex turbine control logic, sequence program, protection interlock and high‑precision PID closed‑loop calculation. It exchanges massive real‑time 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 protocol, connecting HMI, SCADA upper monitoring system and ToolboxST engineering workstation. Reserved PMC expansion slot supports PMCI and other PMC daughter‑cards for communication function expansion. It supports simplex and TMR triple‑modular redundant architecture, undertakes heavy‑load core computing tasks of turbine speed regulation, load control and generator excitation adjustment, ensures stable deterministic real‑time control for large‑scale power generation units.

Product Details

IS215UCVFH2BB (VMIVME‑7650‑83H,350‑007650‑83H C) belongs to UCVH series high‑performance embedded VME controller hardware of GE Speedtronic Mark VI control system.

This single‑slot industrial SBC adopts Intel ultra‑low‑voltage Celeron 1067 MHz high‑speed processor, equipped with large‑capacity SDRAM and CompactFlash to store firmware, complex control application 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. PMC expansion slot can install PMC series sub‑boards to expand system communication resources. 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 heavy‑load unit core control operation.

It belongs to critical high‑performance 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 IS215UCVFH2BB module replacement.
