About the 193X643AFG221
The 193X643AFG221 is what is called a control card. This is a type of printed circuit board or PCB. The 193X643AFG221 was created by General Electric or GE for the 193x series.
The 193X643AFG221 is a large printed circuit board. At the top of this PCB, there is a series of large metal jumper pins. There are fifteen (15) of these large metal jumper pins in total. Directly below this series, there is a line of seven (7) smaller metal jumper pins. Using a jumper, two (2) jumper pins may be connected to each other. On the opposite end of the 193X643AFG221, there are two terminal blocks. The terminal block on the left contains a series of six (6) terminals. The terminal block on the right side contains seven (7) terminals. These terminals are silver and made of metal. These two (2) terminal blocks are identified as 1TB and 2TB. Sitting directly in between these two terminal blocks is one (1) red MOV or metal oxide varistor. One (1) large yellow capacitor is situated directly above the left terminal block. Another large yellow capacitor which is identical to the other is situated along the lower left edge of the 193X643AFG221. Near the center of the 193X643AFG221 there is a large rectangular component. This part is attached to the 193X643AFG221 with black wires. A large rectangular integrated circuit is positioned directly next to this part. Using integrated circuits, space can be conserved on a circuit board. An integrated circuit contains many tiny components which make up an individual network.
