About the IS200TRPGH3B
The IS200TRPGH3B is a GE PCB component manufactured for the Mark VI system. The Mark VI was released by GE as part of the Speedtronic line for turbine management. The IS200TRPGH3B functions as a Gas Turbine Primary Trip terminal board. This is one of several versions of this board; the IS200TRPGH3B is essentially identical to a TRPGH1B board except it for its special handling of 28 V control power. The board cannot be used for Simplex operations and only supports TMR applications. The Mark VI Turbine Control System Series that this IS200TRPGH3B device belongs to has a set of specific functional applications in the control systems and management systems of General Electric-compatible gas, steam, and wind turbine automated drive assemblies. This is seen as quite the massive functional upgrade upon the Mark V Turbine Control System Series of the same name previously developed by General Electric, as the Mark V Series existed with a more restricted set of functional product applications in the control and management systems of General Electric-accepting gas and steam turbine assemblies alone.
Hardware Tips and Specifications
The IS200TRPGH3B has two terminal blocks with 24 screw connections each. A shield bar is installed on the edge to the side of these blocks. The center of the board is populated by nine magnetic relays in three voting circuits that interface with three EDTs (trip solenoids.) In Mark VI systems the IS200TRPGH3B works with the VTUR board, communicating via cables connected to the VME rack where the VT-UR board is located. The board also has components like three cable connectors (JT1/JS1/JR1,) five plug connectors (J1/J2/J3/J4/J5,) transistors, capacitors, integrated circuits, resistors, and diode bridge rectifiers. The board does not have jumpers or any hardware setting located on the board. Current suppression for the board is provided by a MOV located on the TREG board. This IS200TRPGH3B PCB product is actually not the originally-developed device of its specific Mark VI Turbine Control System Series functional role, as that would have to be deemed as the IS200TRPGH3 parent Gas Turbine Primary Trip Board notably not utilizing this IS200TRPGH3B product version's sole B-rated functional product revision.
Diagnostics and specifications of the IS200TRPGH3B can be found in user guides and manuals from the original manufacturer. The board should be treated as a static-sensitive board at all times; AX Control stores and ships components like this in anti-static wraps to protect from possible damage. Given this IS200TRPGH3B product's functional placement within the oftentimes infringed-upon Mark VI Turbine Control System Series, it is not surrounded online by any great amount of originally-printed instructional manual materials. With this being the case, the IS200TRPGH3B functional product number alone may be described through its nature as a decent functional and primary source of IS200TRPGH3B PCB hardware component and component specification information, as it details a series of relevant IS200TRPGH3B Board specifications through its set of consecutive functional naming elements. For instance, the IS200TRPGH3B functional product number starts off with a characteristic and common IS200 series tag which is made responsible for indirectly delegating this IS200TRPGH3B PCB product's normal Mark VI Series assembly version on top of the circuit board's more standard domestic original manufacture location. Some of the other relevant IS200TRPGH3B Board qualities revealed in this manner include this IS200TRPGH3B product's:
- TRPG functional product acronym
- Conformal PCB coating style
- Group three Mark VI Series product grouping
- B-rated functional product revision
