Core Function

VME single‑board computer for Mark VI turbine control system. It acts as the central computing core of VME control rack, executes turbine control algorithms, sequence logic and interlock protection judgment. It exchanges massive real‑time data with each I/O board via VME64 backplane bus, and completes parameter debugging, program download and data interaction with HMI and upper monitoring system through front‑panel Ethernet and serial interfaces. It supports simplex and TMR triple‑modular redundant deployment, undertakes high‑speed closed‑loop control and system fault diagnosis of turbo‑generator unit。

Product Details

The IS215UCVEH2AE (VMIVME‑7614) is UCVE series VME single‑board computer for GE Speedtronic Mark VI turbine control system, hardware base model VMIVME‑7614‑132。

This 6U single‑slot VME CPU board runs QNX real‑time operating system to ensure deterministic fast response for turbine critical control loops. On‑board Compact Flash stores system firmware and application programs. Front panel is equipped with dual Ethernet, dual serial communication ports, LED status indicators and reset button, convenient for field debugging and status observation. It communicates with signal acquisition boards, protection boards and I/O boards inside the rack relying on VME64 backplane bus, completing real‑time computing of speed, valve control, vibration monitoring and trip logic. Equipped with integrated radiator to guarantee stable operation under high‑load computing. Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to harsh environment of power plant turbine hall. It is widely applied in simplex and TMR triple‑modular redundant gas‑steam turbine and generator excitation control cabinets。

It belongs to core CPU spare‑part for Mark VI / EX2100 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.
