IS215UCVFH2A - UCVF UCV Controller Board | GE Mark VI | B7B

The General Electric IS215UCVFH2A (UCVF) is a double-slot Mark VI turbine controller board for GE SPEEDTRONIC™ Mark VI turbine control systems, built on an 850 MHz Intel Pentium III processor with 16 or 128 MB of flash memory and 32 MB of DRAM.

UCVF 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 a separate IP logical subnet configured through the toolbox. 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, IS215UCVFH2A should be matched to the existing controller generation, network configuration, and toolbox revision per GEH-6421 Volume II before ordering a replacement.
