GE IS420UCSBH3A UCSB Controller Module for Mark VIe Turbine Control System

Product Brief Description

The GE IS420UCSBH3A is a UCSB unit controller board for GE Vernova Mark VIe Speedtronic turbine control system. Powered by high-performance processor and QNX real-time operating system, it executes core turbine control logic and communicates with remote I/O packs via IONet industrial Ethernet. This rack-mounted controller supports simplex or redundant deployment, built for heavy-duty gas turbines, steam turbines and generator control in power plants, featuring strong EMC performance and comprehensive hardware self-diagnostics.

Product Functions

• Run real-time turbine control algorithms for speed regulation, fuel valve control, load control and generator protection
• High-speed data exchange with distributed I/O modules through IONet private control network
• Support redundant controller configuration for bumpless switchover to avoid unplanned turbine shutdown
• Collect field sensor signals: temperature, pressure, vibration, valve position and generator electrical parameters
• Process alarm events, sequence of events (SOE) and fault waveform recording for troubleshooting
• Communicate with HMI, historian and upper SCADA system to upload operational data and receive remote commands

Application Scenarios

• Heavy-duty gas turbine and steam turbine control in combined cycle power plants
• Hydro turbine, aeroderivative gas turbine and generator set control systems
• Oil & gas turbine-driven compressor and pump control skids
• Captive power plant and industrial power generation unit safety & control cabinets
• Offshore power generation and marine turbine machinery control systems
