Core Function

VME bus main controller board for Mark VI turbine control system. It acts as the central processing core of the control rack, executes turbine control application programs, completes logic operation, data processing and interlock judgment. It communicates with each I/O board through VME bus, and realizes data interaction with upper monitoring system via Ethernet interface. It supports TMR triple‑modular redundant system configuration, undertakes real‑time control and fault diagnosis work of turbo‑generator unit.

Product Details

The IS215UCVEH2AE (VMIVME‑017614) is UCVE series VME main controller board for GE Speedtronic Mark VI turbine control system.

This single‑slot VME CPU board is the core computing unit of Mark VI control rack, running QNX real‑time system to ensure fast response of turbine closed‑loop control. It relies on VME backplane bus to exchange massive data with various signal acquisition and protection boards inside the rack. Front panel reserves Ethernet and serial communication interfaces, which can connect HMI, configuration tools and upper‑level monitoring equipment for parameter debugging, program downloading and real‑time data uploading. The board is equipped with heat dissipation radiator to guarantee stable operation under high‑load computing conditions. Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to complex working environment of power plant turbine hall. It supports simplex and TMR triple‑modular redundant deployment, widely used in gas‑steam turbo‑generator unit control cabinets.

It belongs to core CPU spare‑part for Mark VI turbine control system, widely used in overhaul and renovation projects of power generation units.

It is important spare hardware for control rack debugging and defective IS215UCVEH2AE board replacement.
