The IS215UCVDH5AN is a high‑performance VME assembly board (controller/logic module) designed for the Mark VI / Mark VIe turbine‑control system family. It serves as a core computing and communication element within the turbine control rack, executing control logic, interfacing with I/O and network subsystems, and supporting high‑availability configurations.
This module is engineered for demanding industrial and turbine‑control environments, including steam turbines, gas turbines, wind‑turbine drives, large compressors, and other rotating‑machinery systems. The board supports real‑time operating systems, multiple I/O and communications ports, status indication LEDs and is designed to plug into the VME rack architecture used in Mark VI/VIe systems.
