Key Features:
  • Dual Ethernet Architecture:​ Redundant network paths ensure continuous communication with HMI, SCADA, and distributed I/O subsystems
  • Real-Time Determinism:​ Microsecond-level response for critical turbine protection and sequencing logic
  • Hot-Swap Capability:​ Field-replaceable design minimizes downtime (when installed in redundant configurations with proper VME backplane support)
  • Triple Modular Redundancy (TMR):​ Supports TMR configurations where multiple UCVE cards synchronize via dedicated buses
Working Principle:​ The IS215UCVEH2A serves as the computational core at the control layer, occupying a single VME slot to execute turbine-specific application code. It processes real-time data from sensors and actuators, runs governor, sequencer, and protective algorithms, and maintains communication over Ethernet for HMI visualization and supervisory control.
Application Scenarios:​ Deployed across diverse turbine control environments including combined-cycle power plants, cogeneration facilities, petrochemical process units, and offshore oil & gas platforms. Typical applications include turbine start/stop sequences, load control, vibration monitoring, and emergency shutdown logic.
System Integration:​ Integrates seamlessly within Mark VI control cabinets. Pairs with GE IS215UCVGH1AB VME Controller Card for redundant configurations, IS200TBAIH1CDD Analog Input Terminal Board for sensor interfacing, and IS200TSVCH1ADC Servo Terminal Board for actuator control. Works in conjunction with IS200TPROH1C and IS200SPROH1ABB Protection Terminal Boards for TMR safety logic.
Installation Requirements:​ Single-slot VME rack installation in Mark VI Speedtronic control cabinets.
Usage Precautions:​ This module is specifically designed for Mark VI platforms. For Mark VIe applications, use GE IS415UCVHH1A VME Controller Board instead. Hot-swap replacement is supported only when installed in redundant configurations with proper VME backplane support.
