Product Description
The IS420ESWBH4A 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 this controller is almost the same. According to the GEH-6725 Mark VIe and Mark VIeS, Control Equipment Hazardous Area Use Guidelines, the IS420ESWBH4A controller is labeled as a Mark VIe, LS2100e, and EX2100e controller. The controller also uses a specific microprocessor, and the microprocessor installed in the device is a 600 MHz EP80579 Intel processor.
On page 22 of the GEH-6725 user manual, there is a small table indicating the electrical/power ratings required to power IS420ESWBH4A. 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.
When installing, installing the IS420ESWBH4A controller in hazardous and non hazardous locations requires multiple certifications. For example, when installed in ATEX Zone 2, IIC group, the required certification is UL DEMKO 12 ATEX 1114875X. All certifications for controllers installed in Class I, Zone 2, Group IIC, non hazardous and Class I, Zone 2, Groups A, B, C, and D are the same, and the certification requirements for these locations are UL E207685.
IS420ESWBH4A is a UCSB controller module developed by GE. The UCSB controller is an independent computer that can execute application specific control system logic. Unlike traditional controllers, UCSB controllers do not host 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.
Surgery
The controller is pre installed with specialized software. It can run steps or blocks. No need to restart the system to make minor changes to the control software online.
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 for initialization
IS420ESWBH4A Advantages
The UCSB controller has the following advantages:
Single module
Built in power supply
No need for jumper settings
No battery
No fans
Smaller panel size
Flash memory can be easily updated
The UCSB controller is installed in the panel and communicates with the I/O package through the onboard I/O network (IONet) interface. IONet is a dedicated Ethernet that only supports Mark controlled I/O modules and controllers.

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.

IS420ESWBH4A = 16×RJ45 + 1×100BASE-LX10 Single-mode LC optical port IONet dedicated switch. Key selection points: Single-mode fiber, supports a maximum inter-cabinet span of 10km, suitable for projects with distributed control cabinets; the IS420ESWBH3A model without optical ports is only suitable for intra-cabinet networking.
Case 1: 300MW Combined Cycle Power Plant (One-to-One 9E Gas Turbine Mark VIe)
System Architecture
The main control cabinet of the gas turbine is equipped with a UCSBH4A controller, and the control cabinet has a large number of I/O ports; the waste heat boiler I/O cabinet is independently located, approximately 600m away from the main control cabinet, exceeding the Ethernet copper cable limit. Network Topology:
Main Control Cabinet: IS420ESWBH4A electrical ports connect to the UCS controller and gas turbine I/O Packs (speed, temperature, fuel valves, vibration protection modules).
IS420ESWBH4A single-mode LX optical ports; single-mode fiber is extended to a second IS420ESWBH4A in the waste heat boiler I/O cabinet.
Remote Switch: Extends boiler drum water level, pressure, flue gas temperature, and bypass actuator I/O.
Reasons for Choosing IS420ESWBH4A:
Long-distance fiber optic extension is required; multimode ESWBH1A would have insufficient transmission distance.
High-density 16 electrical ports accommodate a large number of analog and digital I/O Packs in a star topology.
Class I Div2 explosion-proof certification meets the hazardous area regulations for gas turbine plants.
Function:
Constructing a cross-cabinet IONet real-time network enables unified acquisition of boiler measurement points by the gas turbine main control unit, facilitating coordinated control of combined cycle loads.
Case Study 2: Mark VIeS Safety Control System for a Long-Distance Natural Gas Compressor Station
**Operating Characteristics:
The compressor skid control cabinet is 1.2km away from the local auxiliary equipment cabinet. This is a field compressor station with large temperature differences and strong electromagnetic interference. **Network Solution:
Deploy an IS420ESWBH4A on the compressor skid main control cabinet, connecting it to the Mark VIeS safety controller;
Connect the auxiliary cabinet switch remotely via single-mode fiber optic cable;
All anti-surge valves, pressure interlocks, and overspeed protection I/Os run on IONet;
Selection Considerations:
Ordinary commercial switches cannot be used at field stations; the ESWB series features wide-temperature (-40~+70℃), fanless, dual-redundant 28VDC power supply; the LX single-mode optical port meets kilometer-scale transmission requirements.
Case 3: Integrated Control of Steam Turbine and Waste Heat Boiler in a Large Steel Plant’s Self-Supplied Power Station
Scenario
The steam turbine control cabinet, circulating water control cabinet, and boiler control cabinet are housed in three independent cabinets, with a spacing of 800-1500m. Network Topology: UCS Controller → IS420ESWBH4A (Main Control Cabinet) → Single-mode Fiber Optic → Remote IS420ESWBH4A. Multiple remote cabinets are connected to the main control switch via a star-shaped fiber optic network.
Comparison Solution: If all cabinets are concentrated in one cabinet, the IS420ESWBH3A (without optical ports) can be used; if cabinets are distributed over long distances, the IS420ESWBH4A must be selected.
Case 4: Remote I/O Expansion for the EX2100e Excitation System
The EX2100e excitation controller natively connects to the Mark VIe IONet network. Typical configuration: An IS420ESWBH4A excitation cabinet connects to the excitation controller on one hand, and extends fiber optic cable to the generator’s local I/O cabinet on the other, collecting stator temperature, bearing vibration, and grounding protection signals.
Practical Guide to Product Selection (Commonly Used in Project Design)
Model, Fiber Port Type, Applicable Scenarios
IS420ESWBH3A: No fiber optic port, internal I/O expansion within a single control cabinet, distance <100m
IS420ESWBH1A: Multimode FX, cabinet distance <2km, multimode fiber optic cabling
IS420ESWBH4A: Single-mode LX10, cabinet spacing >2km, long-distance cross-control room scenarios (preferred for mainstream long-distance projects)
Key Implementation and Maintenance Considerations (From Field Cases)
Using ordinary industrial switches to replace IONet switches is strictly prohibited, as it will cause control message latency jitter and false tripping of units.
IONet recommends a star topology; simply cascading too many switches is not recommended to avoid latency accumulation.
IS420ESWBH4A: An unmanaged switch, requiring no configuration, ready to use upon power-up, but fiber optic link attenuation must be tested periodically.
Power Supply Recommendation: Two independent 24/28VDC power supplies. Redundant inputs prevent network outages caused by the loss of a single power supply.
