GE IS420UCSBH3A Mark Vie UCSB Controller Module.The IS420UCSBH3A is a sophisticated UCSB controller module that belongs to General Electric's Mark VIe series products. It is used to execute the control system logic for specific applications. This advanced controller features a unique architecture in which all input/output (I/O) networks are connected to each controller. This ensures comprehensive access to input data and eliminates the problem of single points of failure.

The IS420UCSBH3A employs a unique distributed control architecture where:
All I/O networks are attached to each controller
No application I/O is hosted on the controller itself
Private special-purpose Ethernet (IONet) interfaces connect to I/O packs
The system ensures no single point of application input loss during maintenance
GE Speedtronic Mark VIe IS420UCSBH3A Controller. The UCSB controllers are stand-alone computers that run application-specific control system logic. Unlike traditional controllers where I/O is on a backplane, the IS420UCSBH3A controller does not host any application I/O. Also, all I/O networks are attached to each controller providing them with all input data. The hardware and software architecture guarantees that no single point of application input is lost if a controller is powered down for maintenance or repair. The controller operating system (OS) is QNX Neutrino, a real-time, multitasking OS designed for high-speed, high-reliability industrial applications.
The IS420UCSBH3A controller uses Internal Flash. The UCSB controller mounts in a panel and communicates with the I/O packs through on-board I/O network (IONet) interfaces. The I/O networks are private special-purpose Ethernet that supports only the I/O modules and the controllers.
