Common Applications
Product Precautions
The IS420UCSBH3A is an embedded controller module operating as a standalone computer to execute control system logic for industrial turbine applications. This hardware component belongs to the General Electric Mark VIe product series and is also referenced within the MarkStat control platforms. It runs the QNX Neutrino real-time multitasking operating system to process application-specific parameters without hosting onboard application input and output hardware channels.
- Network-Based I/O Interface – Integrates three 10/100 Ethernet ports to transfer sensor and actuator data with distributed I/O over IONet
- Fault-Tolerant TMR Architecture – Supports single, dual, and Triple Modular Redundant configurations with 2-out-of-3 voting for continuous process uptime
- Dual-Redundant Cooling Fans – Incorporates active internal cooling with redundant fans to eliminate single points of failure during operation

Heavy-Duty Gas Turbine Power Generation
Controls fuel control valves, high-pressure compressor guide vane positions, and exhaust temperature monitoring for large industrial gas turbines.
Thermal Power Plant Steam Turbine Control
Operates electro-hydraulic control (DEH) systems for high-pressure control valves and main stop valves, executing emergency trip systems (ETS) and speed protection.
Offshore Oil & Gas Platforms
Provides continuous process control for turbine units driving main power grids and core water-injection compressors on offshore platforms.
Utility-Scale Wind Turbine Control
Serves as the main controller for large-scale wind turbines (MarkStat platform), executing blade pitch control, nacelle yaw control, and converter interface communication.
Combined Cycle Power Plants
Coordinates plant-wide thermal balance control and load dispatching among gas turbines, heat recovery steam generators (HRSG), and steam turbines.
Large-Scale Cogeneration
Regulates the dynamic balance between extraction steam pressure for industrial heating and generator output power in extraction steam turbines.
When operating the IS420UCSBH3A module, the 24 Vdc input power must be turned off before installation or removal to prevent hardware damage, and the Ethernet interfaces must remain disconnected from external networks to ensure real-time control integrity.
The controller requires vertical mounting to maintain clearance for fanless natural convection cooling, and all modules within redundant or Triple Modular Redundant setups must run identical firmware versions and software configurations to ensure accurate voting.

Technical notes
The IS420UCSBH3A supports single, dual, and Triple Modular Redundant (TMR) control configurations. In TMR setups, three identical UCSB controllers independently run identical control logic and perform 2-out-of-3 voting and synchronization via dedicated networks, enabling online switching without process interruption in the event of a single controller failure.
