About the IC3600AFRA1B1B
The IC3600AFRA1B1B is a GE FANUC Ground Fault Relay Board created as a component for the Mark I and Mark II series. The Mark I was developed in the late 1960s and the Mark II in the early 1970s for the management of gas and steam turbines. Both the MKI and the MKII can function in temperatures ranging from +/- 50 degrees Celsius. They have been used for offshore applications, remote pipeline pumping stations, base-loaded industrial generator drives, and other applications.
The IC3600AFRA1B1B has thirty-two jumper switches on the board. Most of the jumpers are located in two parallel lines flanked by two lines of diodes. The board has four LEDs. These light emitting diodes are red in color. They are marked CR1 through CR4 and are placed along one long edge of the board. There is a male multi-pin mating connector (218A4637P2) located between these LEDs.
One edge of the IC3600AFRA1B1B is populated with twenty-five individual metal pins. These pins are designed to connect to wiring within the frame or chassis of the MkI or MkII system. The board is numbered from two to fifty by tens under the pins.
The IC3600AFRA1B1B has four relays. These are placed on the board in one parallel line. The board has four transistors and two integrated circuits. Capacitors on the IC3600AFRA1B1B may be made from polyester vinyl, aluminum electrolytic material, or another material. Most resistors are metal film.
The IC3600AFRA1B1B has been marked 00/900. It is drilled in two corners. Technical support for this product was provided by GE.
