About the IS215VPROH2B

The IS215VPROH2B is a component made by General Electric for its Mark VI system.  The Mark VI was one of the last gas and steam turbine management systems released by GE as part of the Speedtronic line, which was GE’s primary turbine management series from its inception in the late 1960s with the release of the Mark I through the 1990s with the development of the Mark VI and Mark VIe. The Mark VI is considered a “whole system solution” for turbine management and includes integrated hardware and software built to work in conjunction.

The IS215VPROH2B is an Emergency Turbine Protection card (VPRO.)  This PCB, along with its associated terminal boards (TPRO/TREG,) provides a system of independent emergency overspeed protection for the Mark VI.  Trip solenoids for this module, which is separate from the turbine control system, are located on the TREG board. The turbine can be tripped by either terminal board.  The TREG board provides a positive connection to the solenoids and the TPRO provides the negative. BE aware the VPROH2 is a lower power board that is only able to support one TREG.  If two TREG boards are necessary, please order a VPROH1 board.

The IS215VPROH2B has a front faceplate.  This is built with several components built into the panel, including a power plug, an Ethernet ID connector, an IONet port (Ethernet,) and a parallel port.  There are five additional D-shell ports and several LED indicators located on its surface.

The rear part of the IS215VPROH2B contains two boards stacked together. The top board includes a female power plug that wires into the front faceplate, two backplanes, TP test points, capacitors, integrated circuits, and a number of integrated circuits.  The board also has several vertical connectors and a heat sink component that spans the entire width of the board. The bottom board shares many of these components and has several vertical pin male connectors.  The boards are connected together using screw connections threaded through standoffs.
