The IS200TDBTH6A is a device which is known as a discrete simplex board. This is a form of printed circuit board or PCB manufactured by General Electric or GE. The IS200TDBTH6A is a component device in the Mark VI series for steam and gas turbine controls by General Electric. This series is one of several which make up the Mark lineup. These systems are used to control turbine systems in various industries across the globe.
The IS200TDBTH6A prominently features a collection of twelve large black potentiometers, alternately known as variable resistors. The potentiometers are arranged into three (3) horizontal rows of four components each. Placed on either side of the potentiometers is a long grey component shaped like a rectangle. The lower half of the IS200TDBTH6A is occupied by several rows of very small components. Two (2) long rows of round red components called MOVs or metal oxide varistors are lined up on the left of the IS200TDBTH6A. At the very bottom of the IS200TDBTH6A near the center is a small white connector with three (3) ports. This connect may be used to connect other devices to the IS200TDBTH6A. Several small integrated circuits may be placed on the upper half of the IS200TDBTH6A. A few of these are lined up horizontally in the center and the others are aligned vertically on the upper right side. One (1) small yellow capacitor is featured in the center of the IS200TDBTH6A among the integrated circuits. Two (2) small resistors that are yellow with one (1) black stripe in the middle are positioned at the bottom of the IS200TDBTH6A.
