About the 0-54220-2
The 0-54220-2 is an Automate Auto Bus Link Card made by Reliance Electric. This circuit board is not shaped like other circuit boards. Along the top corner, it is angled instead of coming to a pointed corner. The right side of the circuit board is also strange in the sense that there is a oval opening cut into the circuit board. On the right side of the circuit board there is a black plastic tray that covers the angled corner and some of the circuit board. The black plastic tray has an indented surface that creates a catch cup to hold small pieces. One the right side of the black tray there are two red LED lights that stick out over the oval cut out. The circuit board has twelve black integrated circuits that are staggered across the circuit board in equal distances. The circuit board has five visible black transistors, and two visible silver circle transistors. The circuit board has five visible white resistors with striping, six visible light blue resistors with striping, and three visible light brown resistors with stripping. The circuit board has two large red boxes with tiny white righting on the top near the black plastic tray. The circuit board has two tiny blue squares with even tinier black writing on top near the bottom left of the circuit board. On the left edge of the circuit board there is a black plastic strip that is secured in three places, with thirteen silver half circles popping out of the back edge.
