About the 0-56300-2
0-56300-2 DC Drive Control
The 0-56300-2 from Reliance Electric is a DC Drive Control board typically used within Reliance drive systems. This board may sometimes ship as a Baldor-Reliance or Asea Brown Boveri component. The part you are replacing may be marked as originating from any of these companies. The 56300-2 number will always be reflected in the part id.
The 0-56300-2 is a rectangular shaped card with standoffs located on the bottom side of the board. The board is drilled in several locations to allow surface wires access to both sides of the board. Mounting holes are located in each corner. The board also includes an off-board component with its own mounting hardware. This is a transformer (411027-42A H3276) mounted in a frame. The transformer is wired to the board via red, black, blue and green wires that have been zip-tied together. The length of the wires allows for minimal clearance away from the board for this component. The board has several other surface wired connections including from terminal screw connectors to board, from stab-on connector to board, and from board-to-board points. A large grouping of wires extends from the bottom right edge.
Other board components on the 0-56300-2 include transistors, terminal pins, jumpers, a metal oxide varistor, diodes, and resistors made from carbon composite material. The board includes capacitors made from several materials, of varying capacitance and size. Electrolytic and ceramic capacitors are the primary types used. The board also includes two additional transformers, two relays, a long narrow terminal strip and a doubled terminal strip (two lines of three screws.) There are two right-angled board connectors along one short edge.
More in-depth information regarding the operation or installation of the 0-56300-2 may be found through Reliance manuals, user guides, and data sheets.
