IS215UCVGH1A - UCVG UCV Controller Board | GE Mark VI | B7B

The General Electric IS215UCVGH1A (UCVG) is a single-slot Mark VI turbine controller board for GE SPEEDTRONIC™ Mark VI turbine control systems, built on an Intel Ultra Low Voltage Celeron 650 MHz processor with 128 MB of flash memory and 128 MB of SDRAM.

UCVG provides two 10BaseT/100BaseTX Ethernet ports (RJ-45): the primary port connects to the Unit Data Highway (UDH) for toolbox configuration and peer-to-peer communication, while the second port supports Modbus or private Ethernet Global Data (EGD) networking on a separate IP subnet. The controller runs the QNX operating system with control-block programming (analog and discrete blocks, Boolean logic in relay-ladder format) and supports Boolean, 16-bit and 32-bit integer, and 32-bit/64-bit floating point data types.

For maintenance and procurement teams, IS215UCVGH1A should be matched to the existing controller generation, network configuration, and toolbox revision per GEH-6421 Volume II before ordering a replacement.

Control system parts are provided by GTC Control Solutions, Inc., a wholly owned subsidiary of B7B. Parts are offered in unused, repaired, or remanufactured condition, subject to availability. Each repaired or remanufactured component undergoes functional testing in energized panels, with test reporting and warranty support provided for repair and lifecycle-extension programs.
