The IS215UCVEH2AB is a single board computer designed for use in turbine applications. It is part of the GE Speedtronic Mark VI series and is specifically designed for operating turbine application codes. This board communicates with I/O boards through the VME bus, making it a crucial component in the control of turbine systems. The IS215UCVEH2AB operates within a VME rack, which can have either twenty-one or thirteen slots. It supports an Ethernet port and has a 300 MHz Intel Celeron microprocessor. The board is equipped with 32 Mb of DRAM and 16 Mb of Flash memory, and it uses the QNX operating system, known for its multi-tasking and real-time capabilities, suitable for highly reliable and high-speed industrial applications.

The IS215UCVEH2AB is part of a group of controllers used within the Mark VI system, and it can replace other controllers like the ICVB model. However, it typically requires an upgrade to the backplane. The board is also noted for its compatibility with different memory types and its ability to execute applications with specific execution times, up to one hundred thousand black or rungs per second. Additionally, the software can be modified online without requiring a restart.（IS215UCVEH2A、IS215VPROH1BD、IS215UCVEM06A）
