The GE IS215UCVFH2A is a high-performance Universal Control Unit (UCV) controller designed for the Mark VI system. Part of GE’s Speedtronic line, the Mark VI controls gas and steam turbines. The IS215UCVFH2A manages complex control algorithms for power generation applications.

Hardware Specifications

This double-slot VME board features an Intel Pentium processor operating at 850 MHz. It includes 128 MB or 16 MB flash memory and 32 MB DRAM. The controller’s I/O capabilities are:

• Ethernet: Two Ethernet ports (LAN 1 and LAN 2) enable network communication. LAN 1 connects to Unit Data Highway, while LAN 2 supports expansion I/O.
• Serial Ports: Com1 and Com2 handle serial communication and initial setup.
• USB Port: Provides connectivity for peripheral devices.
• Keyboard/Mouse Port: Allows for local operator interface.
• Monitor Port: An SVGA connector outputs display signals.
• Mezzanine Slot: Accommodates expansion modules and requires jumper configuration.

The board includes integrated circuits, jumpers, test points, inductors, capacitors, and resistors.

Functionality

The IS215UCVFH2A executes control logic based on input data from sensors and other system components. It calculates output signals to actuate control valves and other equipment. The controller’s software is tailored for specific turbine applications, including steam, gas, balance of plant, and marine aeroderivatives.
