GE Speedtronic Mark VI IS200TPROH1B Protective Termination Board

The IS200TPROH1B is a device which is known as a protective termination card. This is a type of printed circuit board or PCB which is rectangular in shape and large. The IS200TPROH1B is a component in the Mark VI series by General Electric or GE. These systems are in charge of managing and automating industrial gas and steam turbines.

The left edge of the IS200TPROH1B is occupied by two (2) large terminal blocks which are black. Both of these terminal blocks feature twenty-four silver metal terminals in the shape of cubes for a combined total of forty-eight terminals. Positioned at the top of the IS200TPROH1B is a pair of transformers which are paired together vertically. These transformers are mostly red with yellow parts on the top. Right next to each of these transformers is a circular red component known as an MOV or metal oxide varistor. The right edge of the IS200TPROH1B is occupied by a collection of connector ports which are black and silver. The three connector ports at the right are larger than the others. These are identified as JZ1, JY1, and JX1 from top to bottom. To the left of these larger connector ports are three (3) small connector ports identified as JZ5, JY5, and JX5 from top to bottom. Paired together with each of these small connector ports beneath each component is a very small yellow capacitor. A long row of silver components identified by the letter L is positioned on the left half of the IS200TPROH1B.
