Product Description
F31X137TRGACG1--TB Relay Card
The F31X137TRGACG1 is a TB Relay Card manufactured by General Electric. It is a long and narrow rectangular board that is approximately 11 inches by 2 ¾ inches in size. This board is designed as a component in the 531x board series. It carries a secondary number of 531X137TRGACG1 and is also marked with codes like FR00/1, 002/1 and 003/1. The F31X137TRGACG1 is typically used in general purpose drive systems like the DC-300.
The F31X137TRGACG1 is composed of only a few components. The most obvious of these is the three terminal strips placed parallel to the long edges of the board. Each of the screw connections located on these strips is individually labeled and numbered along the bottom board edge. There are eighty-four screw connections in all.
Other board components include three ice cube relays, three header connectors, three MOVs, and three resistors. The relays are enclosed general purpose relays protected by a clear case. The header connectors include two twenty-four pin connectors and one fifteen-pin header. MOVs are otherwise known as metal oxide varistors and are used for voltage division. They provide over-voltage protection by providing voltage clamping much like a zener diode might. Resistors are made from carbon composite material. The board is designed with factory made mounting holes.
Publications like manuals, data sheets, and user guides that reference this board number, originally provided by General Electric, will have more detailed information on board operation and on individual components. These publications will also have information regarding installation and proper handling procedures.
