Description

The IS200STAIH1A is a printed circuit board or PCB which is called a DINrail board. The Mark VI is one of several series in the Mark lineup by General Electric. These series were developed to control the operations of turbines in gas and steam turbine systems. The IS200STAIH1A is a large printed circuit board. The upper edge of the IS200STAIH1A is occupied by a large terminal block which is colored green. This terminal block may contain twenty-four (24) small devices known as terminals. The terminals contained inside are cube shaped and have been made from silver metal. At least thirty-four (34) diodes have been placed on the IS200STAIH1A. One row of twenty (20) diodes is situated horizontally on the lower half of the IS200STAIH1A directly above the green terminal block. The second row, which contains fourteen (14) diodes, is positioned in a horizontal row on the upper half of the IS200STAIH1A. These diodes are black and look like small rectangles. Each has been labeled with the letter D and a number. Lined up directly in the center of the IS200STAIH1A is a long line of components. Ten (10) small transistors which are solid black and shaped like half-circles are lined up in the center. Twenty (20) red jumpers are positioned among these transistors. Each red jumper is being used to connect at least two (2) metal jumper pins together. Fourteen (14) potentiometers or variable resistors are also located on the IS200STAIH1A. Ten (10) potentiometers are aligned in the center of the board below the transistors and jumpers. The remaining four (4) are grouped together in the top right corner.
