The IC3600QOXA2 is a type of printed circuit board or PCB. This PCB was created for the Speedtronic Mark I-II system. The Mark I (MKI) and Mark II (MKII) are the first two systems made for the Mark series of gas turbine controls. The Mark turbine series are responsible for controlling and automating the operations of gas turbines.
The IC3600QOXA2 features many various types of electronic components. One (1) large black transformer is positioned on the left edge of the IC3600QOXA2. This transformer is shaped like a rectangle. It has the part number 68A993083G1 written on the top in white writing. Next to this transformer, there is one large relay or contactor. This relay is rectangular and made of grey metal. Written on the top of the relay are the part numbers CR120G40A06FB and 68A997168A03. This relay is also labeled with a voltage of 28 VDC (volts DC). On the opposite end of the IC3600QOXA2, there are two large inductors or coils. These inductors consist of coils of wire which are covered in black plastic. The inductors feature the number 2213PA760387. Positioned next to these inductors is a large rectangular capacitor. This capacitor is solid black and it is labeled with the designator CX. Various small transistors are featured on the IC3600QOXA2. Many of these transistors are round and made of silver metal and others are black and half-moon shaped. One (1) round red button is featured on the left side of the IC3600QOXA2. This button is labeled with the word RESET.
