The IC3600SSVJ1 is what is known as a Fanuc servo valve protection card. This is a type of printed circuit board manufactured by GE or General Electric. The IC3600SSVJ1 is a part of the Mark I-II series. These two series, Mark I and Mark II, have been relied on since 1969 and 1973 respectively. The Mark I and II are the earliest series in the larger Speedtronic Mark line by GE.
The IC3600SSVJ1 features a variety of printed circuit board components. A total of twenty-two (22) small diodes are located in the upper right area of the IC3600SSVJ1. Many of these diodes are red while others are either blue or white. The diodes are labeled with the designator CR, from CR19 at the top left to CR4 at the bottom right. Eight (8) additional small diodes are positioned on the opposite side of the IC3600SSVJ1 on the upper left. Four (4) of these diodes are silver and larger than the others while the rest are smaller and whiteish in color. These diodes are also labeled with the initials CR, from CR2 at the top to CR7 at the bottom. Situated on the bottom half of the IC3600SSVJ1 is a collection of fourteen (14) small resistors. These resistors are arranged in two (2) parallel lines of seven (7) resistors each. The resistors aligned on the left side are red with bands that are red, brown, and grey. The resistors which are lined up on the right side are solid green in color. All of these resistors are labeled with the designator R, as R4 to R17.
