1. Basic Product Information

• Model Correspondence:

  • IS215UCVGM06A & IS215UCVGH1A are both UCVG (Universal Control Variable Generator) single‑slot VME bus master controllers for GE Mark VI Speedtronic systems.

  • Hardware Model: VMIVME-7666-111000 / 350-017666-111000.

• Brand/Series: General Electric (GE), Speedtronic Mark VI Gas/Steam Turbine Control System.

• Core Position: Core computing unit of the Mark VI system, single‑slot VME architecture, responsible for real‑time control, logic operation, data processing and network communication; supports TMR triple‑modular redundancy, directly replaces legacy UCV controllers without backplane upgrade.

2. Core Hardware Specifications (Common + Differences)

Common Core Specifications

• Processor: Intel Ultra Low Voltage Celeron 650 MHz, low power, high stability for industrial real‑time control.

• Memory: 128 MB SDRAM (operating memory) + 128 MB Flash (program/configuration storage).

• Operating System: QNX real‑time multitasking OS, millisecond‑level response, high‑reliability industrial control operation.

• Bus: VME bus, single‑slot installation, compatible with standard VME racks.

• Power: +5V DC (4A typical, 5.4A max); ±12V DC (<1mA).

• Operating Environment: 0°C to 70°C, industrial‑grade for harsh power/energy field conditions.

Interface Differences (IS215UCVGH1A vs IS215UCVGM06A)

• IS215UCVGH1A (Basic Master Version):

  • 2×10/100BaseTX Ethernet (RJ45, LAN1/LAN2 for UDH configuration, peer‑to‑peer, Modbus/EGD networking).

  • 2×RS‑232C serial ports (COM1/COM2 for commissioning/DCS communication), 2×front USB, 1×SVGA video, 1×keyboard/mouse port, reset switch, 4 status LEDs.

• IS215UCVGM06A (Enhanced Communication Version):

  • Retains dual Ethernet, adds ISBus, Genius and other industrial bus interfaces for extended field protocol compatibility and communication capability.

3. Core Functions & Applications

• Performs real‑time control computation, logic execution, data acquisition and condition monitoring for the Mark VI system, supporting core functions of turbine speed regulation, protection and sequence control.

• Supports system configuration validation, redundant communication, local/remote monitoring, compatible with TMR triple‑modular redundancy architecture.

• Applications: Speedtronic Mark VI control systems for gas turbines, steam turbines, combined‑cycle power plants and petrochemical power units.
