UCSB Controller

GE Speedtronic Mark VIe IS420UCSBH1A 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 IS420UCSBH1B 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 IS420UCSBH1B 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.

The Mark VleS UCSBSlA Safety controller and Safety 1/0 modules are used for functional safety loops to achieve SIL 2 and 3 capabilities. Mark VleS Safety equipment is used by operators knowledgeable in safety-instrumented system (SIS) applications to reduce risk in critical safety functions. Safety controllers and distributed 1/0 modules are programmed specifically for safety control use, and this specific control hardware and software has IEC 61508 certification.

IS420UCSBH1B is available in New and Remanufactured Condition. IS420UCSBH1B functions as a Mark VIe/s Controller.

Remanufactured units are the circuit boards overhauled to their factory default. All the reman process is done by our experienced engineers in-house.
