PRODUCT INFORMATION
Product Overview
The General Electric IS200VTURH1B is a VME Primary Turbine Protection Board for Mark VI control systems. This board measures turbine speed to generate the primary overspeed trip signal for system protection. It continuously monitors shaft voltage and shaft current, alerting operators when levels become excessive. On gas turbine setups, the assembly monitors eight Geiger-Mueller flame detectors connected through terminal boards.
The single-slot circuit board features a faceplate with three diagnostic LEDs and one J5 cable connector. Three screw connectors secure the faceplate directly to the printed circuit board assembly. Four passive pulse rate inputs measure turbine speed over an operating frequency range of 2 to 20,000 Hz. Circuit sensitivity allows detection down to 2 RPM on a sixty-tooth wheel to confirm zero speed. This zero-speed detection allows automatic engagement of turbine turning gear when enabled in controller logic.
