About the 0-51377
The 0-51377 is an S-2 Motherboard printed circuit board component manufactured by Reliance Electric. This board component may have been previously marketed under the company names of Asea Brown Boveri or Baldor Reliance depending on the time of production.
The 0-51377 is a rectangular board with a printed grid across its surface. This grid is marked with numbers increasing by 5 from zero to 95 on one axis and marked with letters along the other axis. Letters begin at A and finish at CS. Points along the intersections of these two axes take the place of reference designations.
The 0-51377 is populated by multiple surface-mounted board components. This includes three female slot backplane connectors that allow vertical cards to connect to the 0-51377 board. These are lined up in parallel with each other along the 5, 25 and 45 axes. The board also has a single male terminal strip along its front edge (95.) This is held above the surface of the board by two metal connectors that are screw mounted to the board. The terminal strip is numbered along its front edge. Multiple black wires exit from the back of this component to other locations on the board.
The 0-51377 also has two transformers, several capacitors of various kinds, and several resistors made from different materials. The board has 15 stab-on connectors and several pin connectors. It also has several wire-jumpers (black wires) on its surface. The board is factory drilled along its edge and within the board’s body. It is marked with its identification number and with the code UR5000179. The rear surface of the board is also marked with the code 82746-74D.
