IS420UCSBS1A - UCSB CONTROLER MODULE (SAFETY)

Functional Description

IS420UCSBS1A is a UCSB Controller Module and functions as a safety controller. This module is a GE controller that was built for the Mark VIe and Mark VIeS systems. The business created these technologies for the administration and control of industrial turbine systems, such as gas and steam turbines.

IS420UCSBS1A Features:

• It is used for functional safety loops to achieve SIL 2 and 3 capabilities. This module is a GE controller that was built for the Mark VIe and Mark VIeS systems.
• The IS420UCSBS1A is a safety controller module for Mark VIeS. It is certified for use in hazardous environments, albeit such use may necessitate particular and unusual installation requirements.
• The module is powered by an Intel EP80579 600 MHz CPU.
• The power source for this controller has a nominal voltage of 28.0 VDC (Min 27.4 VDC, Max 28.6 VDC). It can withstand temperatures ranging from -30 to +65 degrees Celsius in its environment.
• For functional safety loops, the module is commonly utilized. These are designed to meet SIL2 and SIL3 requirements. Controllers such as the IS420UCSBS1A are built with control hardware and software that satisfies IEC 61508 certification and use safety-oriented programming.
• The QNX Neutrino operating system is a real-time multi-tasking OS for this UCSB controller. The IS420UCSBS1A is a self-contained computer module. Unlike standard controllers, it does not have a backplane. The unit is self-contained and has its own power supply. There is no battery and no jumper settings are required.
• 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 input that is lost if a controller is powered down for maintenance or repair. The Mark VIeS UCSBS1A 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.

The UCSB controllers offer the following advantages:

• Single Module
• Built-in Power Supply
• Non-Jumper settings required
• No battery
• No Fan (UCSBS1A)
• Dual-redundant fans with IS420UCSBS1A
• Smaller panel Footprint
• Flash memory can be conveniently updated

Installation

The controller is contained in a single module that is direct to the panel sheet metal. The following diagram shows the module envelope and mounting dimensions. All dimensions are in inches. The UCSB is to be mounted to the panel as shown with vertical airflow through the fins to be unobstructed.

Controller Set (UCSBS1A):

• Executes the control logic for the application
• Communicates with the I/O packs each frame
• Interfaces with the ToolboxST* application for configuration
• Interfaces with other supervisory applications through Ethernet

It can be configured in a Simplex, Dual, or Triple Modular Redundant (TMR) arrangement, based on the availability requirements for the system. In Dual and TMR configurations, synchronization of data between controllers is automatically configured and performed in each frame.
