General Electric created the IS200TDBSH6A printed circuit board or PCB as a component in the Mark VI series. Mark VI and the other series which make up the Mark lineup were developed for the automation and management of industrial turbine systems. Mark products have been relied on to control turbine operations in many industries worldwide for several decades.
The IS200TDBSH6A is a relatively large printed circuit board. Sitting on the upper half of the IS200TDBSH6A in the center is a series of twelve (12) rectangular black components. These components have been arranged into three (3) rows of four (4) components each. These black components are bordered on either side by a long grey component. These (2) grey parts are long and rectangular. Two (2) large terminal blocks are seen sitting along the left edge of the IS200TDBSH6A. Both of these terminal blocks are green and labeled with the names TB1 and TB2. Forty-eight (48) terminals are contained within each terminal block. Every terminal has been labeled with white writing as one (1) through forty-eight (48). These terminal blocks are lined up vertically on the left border. Placed on the opposite edge of the IS200TDBSH6A is one (1) mid-sized connector port with many very small “female” connections. At least one (1) solid yellow capacitor is situated in the center of the IS200TDBSH6A directly below the twelve (12) black components. At the bottom of the IS200TDBSH6A on the left side are two (2) resistors labeled as R141 and R140. These two (2) resistors are yellow and have one (1) thin black band in the center.
