IS200VSVOH1B

Description

The IS200VSVOH1B is a circuit board component manufactured by General Electric for the Mark VI.

Mark

The VI was released by GE as part of its long-running and popular Speedtronic gas turbine management series, which began in the 1960s when the company released the Mark

I System. This range of turbine controls continued to develop into the 2000s, including Mark

VI and Mark VIe. Mark

VI includes Ethernet communication capabilities, a PC-based operator interface, and integrated hardware and software specifically designed for turbine control12.

The IS200VSVOH1B is used as a servo control board that drives the fuel/steam valve by controlling four electro-hydraulic servo valves, and also provides pulse rate flow input, LVDT excitation, and LVDT position feedback for triple-redundant systems and simplex systems1

The IS200VSVOH1B is a VME servo control board manufactured by General Electric and belongs to the Mark used in gas turbine control systems

Part of the VI series 1.

The four electro-hydraulic servo valves that operate the steam/fuel valves are guided by a servo control (VSVO) board. Typically, two servo terminal boards are used to separate these four channels (TSVO or DSVO). The valve position is determined using a linear variable differential transformer (LVDT). VSVO performs loop control algorithm 1
