GE IS420UCSBH4A
The GE IS420UCSBH4A is a high – performance controller module designed by General Electric for the Mark VIe series of gas turbine control systems3. It is equipped with a 1066 MHz Intel EP80579 microprocessor, which is optimized for high – speed applications3.

The IS420UCSBH4A executes application code through stand – alone computers called UCSB controllers2. Through the onboard I/O network (IONet) interfaces, the controller is mounted in a panel and communicates with the I/O packs2. The controller’s operating system is QNX Neutrino, a real – time, multitasking operating system developed for industrial applications requiring high speed and reliability2.
