Product Description
The IS420UCSBH1A controller is the first of the UCSB controllers manufactured by General Electric as part of the Mark VIe Control Safety System Series. This controller is similar to the UCSC controller and while it does not have the same hardware the software needed to operate this controller is nearly identical. According to the GEH-6725 Mark VIe and Mark VIeS, Controls Equipment HazLoc Instruction Guide the IS420UCSBH1A controller is labeled as a Mark VIe, LS2100e, and EX2100e controller. There is also a specific microprocessor used with this controller, the microprocessor installed in this device is the 600 MHz EP80579 Intel Processor.
When being mounted there are several certifications that are required to mount the IS420UCSBH1A controller in hazardous and non-hazardous locations alike. For example, when mounted in ATEX Zone 2, Group IIC, the certification needed is UL DEMKO 12 ATEX 1114875X. All certifications regarding the controller being mounted in Class I, Zone 2, Group IIC, non-hazardous, and Class I, Division 2, Groups, A, B, C, and D are the same, the certification requirements for these locations are UL E207685.
Operation
The controller is pre-loaded with application-specific software. It is capable of running rungs or blocks. Minor changes to the control software can be made online without restarting the system.
The IEEE 1588 protocol is used to synchronize the clocks of the I/O packs and controllers to within 100 microseconds via the R, S, and T IONets. External data is transferred to and from the controller’s control system database via the R, S, and T IONets. Process inputs and outputs to I/O modules are included.
This also includes the following in a dual system:
The designated controller’s internal state values and initialization information
The status and synchronization information from both controllers
This also includes the following in a Triple Modular Redundant (TMR) system:
Internal state values for voting and status, as well as synchronization information from all three controllers
Data from the designated controller for initialization
IS420UCSBH1A Advantages
The following benefits are provided by UCSB controllers:
Single module
Built-in power supply
No need for jumper settings
No battery
No fan
Smaller panel footprint
Flash memory can be easily updated
The UCSB controller is installed in a panel and communicates with I/O packs via on-board I/O network (IONet) interfaces. IONet is a private special-purpose Ethernet that supports only Mark controls I/O modules and controllers.

IS420UCSBH1A is a UCSB Controller Module developed by GE. UCSB controllers are self-contained computers that execute application-specific control system logic. The UCSB controller does not host any application I/O, unlike traditional controllers that do. Furthermore, all I/O networks are connected to each controller, providing it with all input data. If a controller is powered down for maintenance or repair, the hardware and software architecture ensures that no single point of application input is lost.

Differentiation Reference for Models in the Same Series
IS420UCSAH1A — UCSA
IS420UCSBH1A — UCSB (This Model)
IS420UCSCH1A — UCSC
The UCSB and UCSC have similar hardware architectures, with the main differences being system licensing, maximum supported I/O scale, and engineering application templates. They are not directly interchangeable and require matching project firmware configurations.
Maintenance Notes
Spare parts replacement should prioritize versions consistent with the Rev version. For replacements across major Rev versions, firmware compatibility needs to be assessed.
The program and database are stored in onboard Flash. Replacing the controller requires reinstalling the ToolboxST project.
The IONet network must use GE-specified industrial shielded network cables and must not be used interchangeably with ordinary office Ethernet.
No built-in battery; the clock relies on IONet IEEE1588 for full network synchronization.
