General Electric created the IS200TPROH1BBB protective termination board. This printed circuit board or PCB was developed for the Mark VI series. Mark VI and the other series in the Mark lineup are used to automate and manage all of the processes in industrial gas and steam turbines.
The IS200TPROH1BBB protective termination board is long and rectangular. A wide variety of electronic components from very small to large are featured on the IS200TPROH1BBB. The left edge of the IS200TPROH1BBB is occupied by two (2) very large terminal blocks that are solid black and labeled with white numbers. Each of the terminal blocks contains a collection of silver metallic terminals labeled from one to forty-eight (48). Sitting at the top of the IS200TPROH1BBB is a pair of relays or contactors that are red squares. These relays contain yellow parts on the top. To the left of each of the relays is a MOV or metal oxide varistor that is solid red. Three (3) black variable resistors or potentiometers are grouped together in a vertical line near the upper right corner of the IS200TPROH1BBB. Each of these variable resistors are identified with the letter R. On the bottom of the IS200TPROH1BBB, several small yellow capacitors may be seen. Many of these are paired together near the bottom while others have been placed individually. A line of small silver components is featured on the left half in a vertical row. Many black rectangular parts called diodes have been concentrated mainly at the bottom of the IS200TPROH1BBB.
