Component Count and Board Construction
This GE IS200VTURH2B board contains over sixty integrated circuits. You will also find thirteen transistors on this board. Furthermore, hundreds of capacitors, resistors, and diodes populate the surface. The assembly includes two backplanes and a multi-position female plug for a daughterboard.
Interfaces, Energy Storage, and Signal Processing
The IS200VTURH2BAB revision provides a single-slot faceplate with three LEDs. Moreover, the board stores pulse rates using digital circuitry for accuracy. It uses a J5 cable connector for external interfacing. The board also checks circuit continuity and integrity automatically.
Functional Logic and Application Context
This Mark VI board processes the median speed signal for primary trip logic. It monitors induced shaft voltage and excessive current levels accurately. The GE IS200VTURH2B controls three primary overspeed trip relays through the TRPx board. For gas turbine applications, this card requires an external 335 V DC supply for flame detectors. GE designed this Mark VI component for Triple Modular Redundancy (TMR) systems.
Installation and Environmental Limits
You must power down the VME rack before inserting this protection board. The operating temperature ranges from 0°C to 60°C . Furthermore, its compact width under 2 cm saves valuable rack space. Always verify the IS200VTURH2BAB revision matches your system requirements.
