The IS200TBTCH1BAA printed circuit board or PCB is a device which is called a thermocouple terminal board. The IS200TBTCH1BAA is one of many components in the Mark VI series by General Electric or GE. The Mark VI is one of the series that make up the Mark family of products made for gas/steam turbine control and automation.
The IS200TBTCH1BAA is a large rectangular circuit board which contains a number of various electronic components including terminals, resistors, capacitors, and ports. Two large terminal blocks which are solid black are positioned along the left edge of the IS200TBTCH1BAA which each contain twenty-four terminals each. These terminals are made of silver metal and in the shape of cubes. Each of these terminals has been identified with the numbers one through forty-eight in white print. These terminal blocks are named TB1 and TB2. Along the right border of the IS200TBTCH1BAA are two (2) jack connector ports which may be used to attach additional components or boards to the IS200TBTCH1BAA. The connector port on the top is labeled as JA1 and the connector port beneath it is called JB1. In the middle of the IS200TBTCH1BAA are two (2) large collections of very small components. Both of these groups have five (5) vertical rows of components. On the left side is a row of resistors which are blue and white. Directly to the right of this row is a row of small silver capacitors. These rows of resistors and capacitors repeat on the right. A long row of components which are identified by the letter L are situated on the right side.
