Product Description
The IS200TBAOH1A is a device which is known as an analog output terminal board. This is a form of printed circuit board or PCB manufactured by General Electric or GE as a component in the Mark VI series. The Mark VI and the other constituent series in the Mark line are used to regulate the processes of gas and steam turbines and have been since the introduction of the Mark I almost fifty (50) years ago.
The IS200TBAOH1A is a printed circuit board or card which is long and slim in size. Two (2) large devices called terminal blocks have been positioned on the left edge of the IS200TBAOH1A. The terminal blocks are green and contain a series of small metal components called terminals. The blocks are named TB1 and TB2. The right half of the IS200TBAOH1A is taken up with six (6) connector ports. These ports each contain a number of small holes called “female” connectors which are used to attach other devices to the IS200TBAOH1A. The connector ports are laid out in vertically in three (3) pairs of two (2) ports each. The bottom part of the right half of the IS200TBAOH1A is occupied by a collection of potentiometers or variable resistors arranged into two (2) vertical rows. Seven (7) potentiometers are lined up in each row. An additional pair of potentiometers has been placed below these two rows. The IS200TBAOH1A has been lined with many small capacitors which are square shaped. Also featured on the IS200TBAOH1A are many very small resistors which feature multicolored bands.
