Description

IS420UCSBH4A GE controller module Mark VIe series

The IS420UCSBH4A is a controller module manufactured by General Electric and part of the Mark VIe family for gas turbine control systems equipped with 1066 MHz Intel EP80579 microprocessors.

The application code is executed by a separate computer called a UCSB controller.

Through the onboard 1/0 Network (IONet) interface, the controller is mounted in the panel and communicates with I/O packets.

Only Mark controls the I/O modules and controllers, powered by a dedicated dedicated Ethernet network called IONet.

The controller’s operating system (OS) is QNX Neutrino, a real-time multitasking operating system developed for industrial applications that require extreme speed and reliability.

UCSB controllers lack any application I/O host compared to traditional controllers that host application I/O on the backplane.

In addition, each controller has access to all I/O networks, providing it with all input data.
