GE IS200VTURH1B IS200VTURH1BAB Mark VI VME Protection Card

The GE IS200VTURH1B board delivers critical overspeed protection for the Mark VI series. This VME module also carries the revision code IS200VTURH1BAB . It monitors turbine speed and shaft conditions continuously. The board acts as the primary safety interface for gas and steam turbines.

Technical Specifications of GE IS200VTURH1B IS200VTURH1BAB

Inputs, Interfaces, and Component Count

This printed circuit board features four passive magnetic speed inputs. These channels accept a range from 2 to 20,000 Hz . Moreover, the GE IS200VTURH1B includes eight flame detection channels for Geiger-Mueller detectors. The card controls three primary overspeed trip relays through the TRPx board. For connectivity, a single-slot faceplate provides three LEDs and one J5 cable connector.

The IS200VTURH1BAB revision contains over sixty integrated circuits. You will also find thirteen transistors on this board. Hundreds of capacitors, resistors, and diodes populate the surface. Additionally, the assembly includes two backplanes and a multi-position female plug for a daughterboard.

Energy Storage, Functional Logic, and Environment

The GE IS200VTURH1B processes the median speed signal for primary trip logic. It monitors induced shaft voltage and excessive current levels accurately. The board stores pulse rates using digital circuitry to ensure precision. For gas turbine use, this card requires an external 335 V dc supply for the flame detectors. GE designed this Mark VI component specifically for Triple Modular Redundancy (TMR) systems.

The operating temperature ranges from 0 to 60 °C . Its compact width under 2 cm saves valuable rack space. Always power down the system before installing the GE IS200VTURH1B IS200VTURH1BAB board.
