Frequently Asked Questions about IS200TREGH1A

Where are the diagnostics for the IS200TREGH1A model contained?

The diagnostics for the IS200TREGH1A model are housed in the VRPO section. The diagnostics from the VPRO cover the following; contact feedback, trip relay driver feedback, solenoid voltage, contact feedback, economizer relay driver feedback, servo clamp relay driver and contact feedback, solenoid voltage source, and K25A relay driver and coils. The JZ1, JY1, and JX1 connectors each have their own ID device that is interrogated by the VPRO I/O processor board. The ID device is a read-only chip that is coded with the plug location, revision number, terminal board serial number, and board type. For more information on the diagnostics of the TREG model, refer to the attached instruction manual.

What are the trip inputs associated with this model?

There are several trip inputs associated with the IS200TREGH1A model. The inputs are as follows; 1 Emergency Stop hardwired trip interlock at 24 VDC and seven trip interlocks to the VPRO protection module at 125/24 VDC.

Product Description

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. 

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.

Reviews For IS200TREGH1A

Internal Review
(5.0)

The IS200TREGH1A model has the ability to remove the power and control the attached VPRO solenoid circuits. When the model performs this function, it will remove the positive power, with the associated TRPG model removing the negative power. - AX Control Tech
