Product Overview
The GE IS215UCVEM01A and IS215UCVEH2AF are high-performance VME-based controllers designed for GE’s Mark VI turbine control system. These modules function as critical components in industrial automation, leveraging the VMIVME-7614-133 (also labeled 350-017614-133 E) hardware platform to manage complex processes in gas/steam turbines and power generation systems. The IS215UCVEH2AF features a dual-sided design with an integrated front panel containing status LEDs and a reset button, while the IS215UCVEM01A serves as a robust interface for analog/digital I/O signals, including LVDT inputs, servo valve outputs, and vibration monitoring channels . Both modules operate within GE’s Mark VI framework, ensuring precise control over critical parameters like fuel flow, temperature, and speed to enhance machinery reliability and operational efficiency in demanding environments .
Engineered for real-time data processing, these controllers support high-speed communication via COREBUS and integrate with terminal boards (e.g., TBQA, TBQC) for signal conditioning. The IS215UCVEM01A and IS215UCVEH2AF are built to withstand industrial harshness, with operating temperatures ranging from -30°C to 65°C and compliance with IP65 standards for dust/water resistance. Their role in automating turbine protection sequences—such as overspeed prevention and combustion stability—makes them indispensable for minimizing downtime in power plants and oil/gas facilities .

Key Features and Advantages
Advanced Processing Capabilities: The IS215UCVEH2AF integrates a 300MHz Intel Celeron processor with 32MB DRAM, enabling rapid execution of control algorithms for turbine governance. This processing power facilitates real-time monitoring of up to 750 I/O signals, critical for scenarios requiring immediate response to anomalies like pressure surges or temperature deviations .
Dual-Side Design with Diagnostic Accessibility: Featuring a front panel with LED indicators and a reset button, the IS215UCVEH2AF allows operators to swiftly assess module health and initiate recovery without system shutdown. This design reduces mean time to repair (MTTR) by 40% compared to non-modular alternatives .
Seamless System Integration: Both the IS215UCVEM01A and IS215UCVEH2AF support industry-standard protocols (Modbus, TCP/IP) and GE-specific networks like EGd. This interoperability enables data exchange with higher-level systems (e.g., DCS/SCADA) and third-party devices, ensuring unified plant control .
Robust Environmental Durability: With an operating temperature range of -30°C to 65°C and IP65-rated protection, these modules resist dust, moisture, and electromagnetic interference. Such resilience ensures stable performance in turbine halls or offshore platforms where contaminants and vibrations are prevalent .
Application Areas
The IS215UCVEM01A and IS215UCVEH2AF are deployed primarily in energy and industrial sectors. In power generation, they govern gas/steam turbines by regulating fuel valves, monitoring combustion dynamics, and executing emergency shutdowns via integrated relay drivers. For oil and gas applications, these controllers manage compressor stations in pipelines, ensuring anti-surge control and efficiency optimization .
Additionally, the modules are used in manufacturing automation for large rotating machinery, such as metal processing mills and chemical reactors, where they handle analog signals (e.g., 4–20mA inputs for pressure) and digital sequences. Their compatibility with GE’s System 1® software further enables predictive maintenance for wind turbines and hydroelectric plants, reducing unplanned outages by 25% .
