About the IS200TREGH1A
This IS200TREGH1A Turbine Emergency Trip Board printed circuit board product offering was originally designed and produced specifically for placement in their Mark VI Turbine Control System Series, as was described just above in this IS200TREGH1A Turbine Emergency Trip Board's brief product description. The Mark VI Series, as you have more than likely been able to deduce based off of its full extended series name included here, has a set of specific functional applications as intended by General Electric in the control or management systems of GE-compatible gas, steam, and wind turbine automated drive assemblies. The Mark VI Turbine Control System Series actually represents quite the marked improvement upon the Mark V Series of the same name, as the Mark V Series possessed gas and steam possible applications alone, shirking the Mark VI Series's coming alternative energy settings compatibility. The Mark VI Series is also seen as quite the hot prospect on its greater automated industrial promotional marketplace given its status as one of the final-developed GE Mark product series to incorporate the patented Speedtronic control system technology across a range of differing functional devices.
Hardware Tips and Specifications
Mark VI IS200 Turbine Emergency Trip Model IS200TREGH1A was designed by General Electric to work alongside a VPRO Turbine Emergency Trip Module. When the TREG model is used with a VPRO I/O Processor Board, it also works with two other terminal boards, which are the TPRO/Turbine Protection and TRPG/Primary Trip boards. The TREG model is designated as the positive side to the available 125 VDC solenoids, while the TRPG model is the negative side. While being used with the VPRO board, the IS200TREGH1A model will control the twelve relays available on this model. Nine of the relays will form three groups of three to form vote inputs, which will then control the three trip solenoids available on the VPRO processor. A second TREG board can be connected to the VPRO processor, which will be driven from the VPRO board to the J4 connector. This IS200TREGH1A Turbine Emergency Trip Board product is actually not the originally-designed device of its specific Mark Series functional role, as that would be considered the IS200TREGH1 parent PCB notably missing this IS200TREGH1A Turbine Emergency Trip Board's sole A-rated functional product revision.
Typically the IS200TREGH1A model can be used in either Simplex or Triple Modular Redundant (TMR) systems. When the TREG model is being used in TMR systems, it will be completely controlled by the VPRO board through the trip solenoids and the J2 power cable connections. When the model is used in a Simplex system, an extra cable will be added to carry a trip signal from the J1 connector to the associated TSVO terminal board; the extra cable will provide the TSVO model with a Servovalve clamp function upon a turbine trip function. Together the TREG and TRPG models will control the trip solenoids on the VPRO model; when the two models are working together, either one of them has the ability to remove the power and actuate the hydraulics within the Mark VI systems to close the fuel or steam valves. For more information on the function of the IS200TREGH1A board, refer to the attached documentation, which covers the function between the TREG, TRPG, and VPRO boards. This IS200TREGH1A Turbine Emergency Trip Board is not surrounded by a plethora of originally-developed instructional manual materials, which lends a new relevance to the IS200TREGH1A functional product number indirectly delegating this IS200TREGH1A PCB's:
- Domestic original manufacture location
- Conformal PCB coating style
- Singular A-rated revision
