The IS200TRLYH1BEC is a device known as a termination relay card. The IS200TRLYH1BEC is a component in the Mark VI series by General Electric or GE. The Mark VI is one of the series in the Mark lineup of gas and steam turbine controls.
The IS200TRLYH1BEC is a rectangular circuit board with a number of various components ranging from large to small. The left edge of the IS200TRLYH1BEC is occupied by a pair of two (2) large terminal blocks. These terminal blocks are solid black and they contain twenty-four silver metal terminals each. The terminals are labeled with the numbers from one (1) to twenty-four (24) and twenty-five (25) to forty-eight in white printing. To the right of the terminal blocks is a series of transformers that are tall and rectangular in shape. They are silver and black and have been covered with transparent plastic. There are twelve (12) of these transformers on the board in total. The six (6) transformers grouped on the top half of the IS200TRLYH1BEC are surrounded by a series of components. Six (6) circular black transistors are lined up along either side of the IS200TRLYH1BEC. A red MOV or metal oxide varistor which is circular is paired together with each transistor. Six (6) blue capacitors which are rectangular have been aligned to the right of the IS200TRLYH1BEC. Two white connectors are sitting at the top edge of the IS200TRLYH1BEC. Each of these connectors contain three small ports. Another one (1) of these white connectors is placed at the lower edge of the IS200TRLYH1BEC. This connector features a series of four (4) ports. The IS200TRLYH1BEC contains many small integrated circuits positioned all around the circuit board.
