The IS200TRLYH1BGF is a device which is called a termination relay card. This is a sort of PCB or printed circuit board which was produced by GE or General Electric. The IS200TRLYH1BGF is a component in the Mark VI series by General Electric. The Mark VI series is just one of several series which make up the Mark family of gasoline and/or steam turbine controls.
The IS200TRLYH1BGF circuit board is large and rectangular, containing numerous electronic components. The largest components on the IS200TRLYH1BGF are two (2) long black terminal blocks. These are devices which can hold a collection of silver metal components called terminals. The terminal blocks on the IS200TRLYH1BGF each feature twenty-four (24) of these small terminals. Each has been numbered from one to forty-eight. The center of the IS200TRLYH1BGF is occupied by a series of relays or contactors which have been arranged into a vertical line. The relays are grey and black with covers that are made from transparent plastic. Six (6) black transistors are positioned on either side of the relays on the top half of the IS200TRLYH1BGF. Paired together with each of these transistors is a red MOV or metal oxide varistor which is round in shape. One (1) additional metal oxide varistor is positioned at the lower left corner of the IS200TRLYH1BGF. Many integrated circuits can be found throughout the IS200TRLYH1BGF. Six (6) capacitors which are solid blue may be found arranged in a line to the right of the transistors and metal oxide varistors.
