IS200VTURH1B | General Electric Mark VI printed circuit board

Description 

The IS200VTURH1B is a Primary Turbine Protection board manufactured by GE specifically for the Mark VI system, a gas/steam turbine management system within the 'Speedtronic' line. The Mark VI system features a TMR (triple modular redundant) architecture and an integrated HMI (human-machine interface) for centralized turbine data access. 

This board, the IS200VTURH1B, fulfills several key functions, including monitoring induced shaft current/voltage levels with alarming capabilities for excessive levels, generating the primary overspeed trip by measuring turbine speed, and controlling the three primary overspeed trip relays belonging to the TRPx terminal board. Additionally, it oversees the monitoring of eight Geiger-Mueller flame detectors in gas turbine applications.

Information About IS200VTURH1B

The IS200VTURH1B, developed by GE, serves as a Primary Turbine Protection board within the Mark VI system, a gas/steam turbine management system under the 'Speedtronic' line. The Mark VI system incorporates a TMR (triple modular redundant) architecture and features an integrated HMI (human-machine interface) for centralized turbine data access. 

Functionally, the IS200VTURH1B performs multiple tasks, including monitoring induced shaft current/voltage levels, with alarming capabilities for excessive readings, measuring turbine speed to initiate the primary overspeed trip, and controlling the three primary overspeed trip relays, which are part of the TRPx terminal board. Additionally, it oversees the monitoring of eight Geiger-Mueller flame detectors in gas turbine applications. 

Physically, the IS200VTURH1B features a connected single-slot faceplate housing three LED indicators and a single cable connector (J5). The faceplate is secured to the PCB via three screw connections. The PCB is constructed with over sixty integrated circuits, thirteen transistors, numerous capacitors and resistors, as well as diodes and inductor coils. It incorporates two backplanes, a female multi-position plug for connecting a daughterboard, and several connectors comprised of conductive dots and traces. The board is pre-drilled at multiple points to facilitate various mounting options, including four drill holes designated for standoffs to support the aforementioned daughterboard. Markings such as 6BA01, 94V-0, and Type 6 are present on the board.
