Core Function

UCVE VME single‑board controller for Mark VI turbine control system. It runs QNX real‑time operating system to execute turbine core control logic, sequence control, protection interlock and PID closed‑loop calculation. It communicates with other VME I/O boards through VME64 backplane bus, collects field process data and outputs control commands. Dual Ethernet ports support EGD/Modbus communication for connecting HMI and upper monitoring system. It supports simplex and TMR triple‑modular redundant architecture, undertakes key control tasks of turbine speed regulation, load adjustment and generator excitation control, ensures deterministic real‑time control of power generation units.

Product Details

IS215UCVEH2AB (VMIVME‑7614) belongs to UCVE series embedded VME controller hardware of GE Speedtronic Mark VI control system.

This industrial single‑board computer adopts Intel Celeron 300 MHz industrial processor, equipped with DRAM and Flash storage to store firmware, control application and event log data. Rich front‑panel interfaces realize network communication, serial debugging and local display function. The VME64 backplane realizes high‑speed data interaction with each functional board inside the rack. On‑board hardware self‑diagnosis continuously monitors operating state and reports fault information. 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 IS215UCVEH2AB module replacement.
