　　IS420ESWAH1A Other names:

　　Editable Controller IS420ESWAH1A

　　IS420ESWAH1A Input/Output Module

　　Analog controller IS420ESWAH1A

　　The IS420ESWAH1A controller is the first UCSB controller in the Mark VIe control safety system series manufactured by General Electric. This controller is similar to the UCSC controller, although the hardware is different, the software required to operate the controller is almost the same. According to the GEH-6725 Mark VIe and Mark VIeS, Control Equipment Hazardous Area Usage Guidelines, the IIS420ESWAH1Acontroller is labeled as Mark VIe, LS2100e, and EX2100e controllers. The controller also uses a specific microprocessor, which is a 600 MHz EP80579 Intel processor installed in the device. Unlike traditional controllers, UCSB controllers do not carry any application I/O. In addition, all I/O networks are connected to each controller, providing it with all input data. If the controller loses power due to maintenance or repair, the hardware and software architecture ensures that no application input points are lost.

　　On page 22 of the GEH-6725 user guide, there is a small table indicating the electrical/power ratings required to power IS420ESWAH1A. The ratings are as follows: minimum voltage is 18 volts DC, maximum DC is 30 volts, and nominal power ratings are 24 volts and 28 volts DC. The maximum current rating used by this device is 1.5 ADC.

　　During installation, multiple certifications are required to install the IS420ESWAH1A controller in hazardous and non hazardous locations. For example, when installed in ATEX Zone 2, Group IIC, the required certification is UL DEMKO 12 ATEX 1114875X. All certifications for controllers installed in Class I, Zone 2, IIC group, non hazardous and Class I, Zone 2, A, B, C, and D groups are the same, and the certification requirements for these locations are UL E207685.

　　Surgery

　　The controller comes pre installed with specialized software. It can run steps or blocks. Minor changes can be made to the control software online without the need to restart the system.

　　The IEEE 1588 protocol is used to synchronize the clock of I/O packets and controllers to within 100 microseconds through R, S, and T IONets. External data is transmitted to or from the control system database of the controller through R, S, and T IONets. This includes the process inputs and outputs of the I/O module.

　　This also includes the following in the dual system:

　　Specify the internal state values and initialization information of the controller

　　Status and synchronization information from two controllers

　　This also includes the following in Triple Modular Redundancy (TMR) systems:

　　Internal state values for voting and status, as well as synchronization information from all three controllers

　　Data from the specified controller, used for initialization

　　IS420ESWAH1A Advantages

　　The UCSB controller has the following advantages:

　　Single module

　　Built in power supply

　　No need for jumper settings

　　No battery

　　Without a fan

　　Smaller panel size

　　Flash memory can be easily updated

　　The UCSB controller is installed in the panel and communicates with the I/O pack through the onboard I/O network (IONet) interface. IONet is a dedicated Ethernet that only supports Mark controlled I/O modules and controllers.

　　Features

　　Microprocessor: 600 MHz Intel EP80579

　　Memory: 256 MB DDR2 SDRAM with error correction code (ECC), SRAM supported by flash memory, NAND flash memory size of 2 GB

　　Operating System: QNX Neutrino

　　Weight: 2.4 pounds

　　Installation

　　The UCSB controller is installed in a separate module that is directly connected to the panel metal plate.

　　The UCSB controller should be installed on a heat sink panel that allows for vertical air circulation.
