The Relay Card marked IC3600KRSD1 is a relay board component for the Speedtronic Mark I and Mark II series. The first GE Speedtronic steam/gas turbine management series to be developed or released, the MK1 (released in 1969) and the Mark II (released in 1973) have been used for marine drives, electric utility peaking turbines, remote pipeline pumping drives, and compressor drives. Even though these two series have since become obsolete due to the development and release of newer Speedtronic systems like the Mark VIe and the Mark V, the MKI/MKII are still in use in many locations today. This may be due to GE’s focus on creating systems that would adaptable, scalable, and long-lasting.
The IC3600KRSD1 is built with six relays. The relays are marked with the GE logo, with the relay diagram, and with two codes. It is also marked with 28 VDC and 10 VA. Several wires are attached to one end of each relay. These wires connect from the relays to a line of metal pins along the edge of the board. These metal pins function as a communication device. The board is lettered and numbered underneath these pins. The letters under these pins correspond to the colors of the wires that may connect to any particular pin. For example, if a pin can accept a yellow and green pin, it will be marked Y and G underneath that pin.
