Description

The IS200SRLYH2A is a device which is called a simplex terminal relay board. This is a type of printed circuit card or circuit board which is made for the Mark VI series by General Electric or GE. The Mark VI is one of several series in the Mark line made for the control and automation of gas and steam turbine processes. These series have been relied on to operated turbines for nearly fifty (50) years. The IS200SRLYH2A is a large square printed circuit board with many components which range from very small to very large. The largest component is situated on the far left side of the IS200SRLYH2A. This component is a large terminal block which is labeled as TB1. This terminal block is a device which contains up to forty-eight (48) small metal terminals. Each terminal is labeled with its number in white print. Situated right next to this terminal block on the right side is a long grey component labeled as JW1. Two small components are sitting above this grey component. The small device on the top is a rectangular resistor and the component below it is a very small black capacitor also shaped like a rectangle. A total of twelve (12) large rectangular components known as relays or contactors are arranged in horizontal lines in the center of the IS200SRLYH2A. These relays are all solid black with white writing on the top. They have been arranged into three (3) rows of four (4). A second large grey component just like the other is placed on the other side of these black relays.
