GE IS420UCSBH4A CONTROLLER MODULE
Description:
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.
The UCSB controllers offer the following advantages:
* Single module
* Built-in power supply
* No jumper settings required
* No battery
* Nofan (UCSBSIA, UCSBHIA, UCSBHAA) * Dual-redundant fans with IS420UCSBH3A
* Smaller panel footprint
* Flash memory can be conveniently updated
