About the IS200TREGH2B
The IS200TREGH2B is a PCB board component created by GE for the Mark VI system. The Mark VI was one of the last of the Speedtronic series of gas and steam turbine management systems released by GE. The MKVI includes integrated redundant backups on things like turbine flame detection, shaft voltage monitoring, and speed input monitoring. The Mark VI Turbine Control System Series that this Gas Turbine Emergency Trip terminal board device belongs to, as it is known by its full extended product series title, exists with a series of possible functional applications in the management and control systems of General Electric-compatible gas, steam, and wind turbine automated drives and automated drive assemblies. This must be characterized as a significant functional improvement upon the Mark V Turbine Control System Series of just about the same full extended product series title that immediately preceded this Gas Turbine Emergency Trip terminal board product's Mark VI Series, as the Mark VI Series was created in part to add the alternative energy-based wind turbine possible functional environment onto the gas and steam turbine environments established with the Mark V.
Hardware Tips and Specifications
The IS200TREGH2B is a Gas Turbine Emergency Trip terminal board. This card provides power to three emergency trip solenoids. It is controlled by the I/O controller. This board works in conjunction with a TRPG board. The IS200TREGH2B provides the positive side of the dc power to the emergency trip solenoids while the TRPG provides negative power. There are several versions of the TREG board; this version is designed for use in 24 V dc applications with control power from board connectors (JX1, JY1, and JZ1) being diode combined to create redundant power for status feedback circuits and power for economizing relays. The IS200TREGH2B is designed with twelve relays placed on the board in two lines of six. Nine of these form three groups of three to vote inputs controlling the trip solenoids. The board has an additional four smaller relays that provide other board functions. The board has three D-type (female) connectors located along the rear edge of the board. It has several plug connectors, including a 2-position, a 3-position, and a 12-position plug. The board has two terminal boards (TB1 and TB2,) placed side by side along the front edge. The board is also populated by multiple metal oxide varistors (MOVs) and a 10 Ω, 70 W economizing resistor. These components are used for current suppression.
Generally, this IS200TREGH2B Trip Emergency Terminal Card printed circuit board product offering is not followed by very many originally-printed instructional manual materials onto the internet, as its greater Mark VI Turbine Control System Series has frequently been copyright infringed-upon online. While this may be true, the IS200TREGH2B functional product number itself can be rolled out as a decent supplementary medium for retrieval of relevant IS200TREGH2B Board hardware component and component specification information, as it codes for a specific series of important details through its series of arranged functional naming elements. For instance, this IS200TREGH2B functional product number is started off through its inclusion of the dual-functional IS200 series tag that was designed to indirectly delegating both this IS200TREGH2B Gas Turbine Emergency Trip terminal board's normal Mark VI Turbine Control System Series assembly version on top of its almost-certain domestic original location of General Electric manufacture. To be a little more specific, this Gas Turbine Emergency Trip terminal board product was likely produced out of General Electric's Salem, Virginia factory plant location. Some of the other relevant Gas Turbine Emergency Trip terminal board details indicated in its part number include its:
- TREG functional product acronym
- Conformal PCB protective coating type
- Group one Mark VI Series unique product grouping
- Singular B-rated product revision
