GENERAL ELECTRIC IS420UCSBH3A CONTROLLER MODULE
Description：
IS420UCSBH3A is GE VIe UCSB controller with dual-redundant fans.
The UCSB controllers are stand-alone computers that run the application code. The controller mounts in a panel, and communicates with the I/O packs through on-board I/O network (IONet) interfaces. IONet is a private special-purpose Ethernet that only supports Mark* controls I/O modules and controllers. The controller operating system (OS) is QNX Neutrino, a real time, multitasking OS designed for high-speed, high-reliability industrial applications. Unlike traditional controllers where I/O is on a backplane, the UCSB 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 Mark VIeS UCSBSIA Safety controller and Safety I/O modules are used for functional safety loops to achieve SIL 2 and 3 capabilities. Mark VIeS Safety equipment is used by operators knowledgeable in safety-instrumented system (SIS) applications to reduce risk in critical safety functions. Safety controllers and distributed I/O modules are programmed specifically for safety control use, and this specific control hardware and software has IEC 61508 certification.

FAQ:
What's the difference between IS420UCSBH3A and IS420UCSBH4A?
The most remarkable feature is IS420UCSBH3A with dual-redundant fans,  IS420UCSBH4A doesn't have the fan.
For the microprocessor, IS420UCSBH3A is 1200 MHz Interl EP80579, IS420UCSBH4A is 1066 MHz Interl EP80579.

How to install IS420UCSBH3A?
The controller is contained in a single module that mounts directly to the panel sheet metal. The following diagrams display the module envelope and mounting dimensions. All dimensions are in inches. The UCSB is to be mounted to the panel as shown with vertical air flow through the fins to be unobstructed.
