Description

The IS200TGENH1A is a device called a termination board. This is a printed circuit board or PCB made for the Mark VI series by General Electric. The Mark VI and the other series in the Mark line were designed to efficiently manage the processes of gas and steam turbines. Mark systems have been used to automate industrial turbine processes since the Mark I was first introduced in 1969. The IS200TGENH1A printed circuit board contained a number of various electronic components. Three (3) inductors, which are sometimes called coils, are featured on the lower center part of the IS200TGENH1A in a vertical line. These components are made up of coils of wire covered with wire material. Four (4) terminal blocks have been positioned on the left edge of the IS200TGENH1A. The terminal block on the top, labeled as TB1, is solid black and very large. Three (3) additional terminal blocks are situated underneath the TB1. These are also solid black but much smaller than the other. They have been named TB2, TB3, and TB4. A group of transformers have been placed in the center of the IS200TGENH1A. These transformers are black with yellow on the top. Six (6) red MOVs or metal oxide varistors are placed to the left of the transformers. Each of these MOVs is circulars. Situated above these transformers, there is a collection of square black components known as diodes. These have been arranged into three (3) rows of eight (8) diodes each. A series of eight (8) jumpers are placed among these square diodes. The jumpers are red and have been used to connect metal jumper pins together.
