Products Description
GE IS420UCSBH1A Mark VIe UCSB Universal Controller Single Board
GE IS420UCSBH1A is the UCSB universal single-board controller for GE Mark VIe turbine distributed control system. It adopts Intel EP80579 processor and QNX real-time operating system, responsible for executing turbine control logic, processing IONet data and communicating with HMI/SCADA system.
This controller uses passive heat dissipation design without fan, equipped with ECC memory and multiple Ethernet ports for redundant network communication. It supports simplex configuration for plant auxiliary control. It is discontinued legacy spare widely used for gas and steam turbine control system upgrade and maintenance in power plants.
