GE IS200VPROH2B Mark‑VI VME Processor Control Board

Product Description

IS200VPROH2B is a high‑performance VME‑bus processor board designed exclusively for the GE Speedtronic Mark‑VI turbine‑control system. It serves as the main CPU controller, 

executing real‑time turbine control logic, sequence programs and fault‑diagnosis algorithms. Equipped with onboard memory, communication interfaces and VME64 backplane connector,

 it exchanges data with I/O boards and other rack modules. Widely deployed in gas‑turbine, steam‑turbine and generator‑set control cabinets inside thermal‑power stations and heavy‑duty

 power‑generation plants.
