Functional Description

IS215UCVFH2A is a Double-Slot Controller Board manufactured and designed by General Electric as part of the Mark VI innovation series VME platform used in gas turbine control systems. The UCVF is a double-slot board with a Pentium III processor running at 850 MHz. It has 32 MB of DRAM and 16 or 128 MB of flash memory. Connectivity is provided by two 10BaseT/100BaseTX (RJ-45 connection) Ethernet ports.

IS215UCVFH2A Features

  • The UCVF's initial Ethernet port enables peer-to-peer communication and connecting to the UDH for configuration. On the UCVF, the second Ethernet port is intended for usage on a different IP logical subnet.
  • Through the toolbox, the second Ethernet port can be configured. Every time the rack is powered up, the controller verifies the toolbox configuration versus the installed hardware.
  • The top-of-the-line current generation controller, the double-slot UCVF, is only utilized in systems that need it. The single-slot UCVG can be used to directly replace any prior controller version without the need for a backplane upgrade and offers performance comparable to the UCVE and UCVF.
  • The UCVF can also take the place of controllers from older revisions, however, this requires a backplane upgrade. A 10Base2 to 10Base-T Ethernet cable upgrade is also necessary when replacing a UCVB.
