About the 0-51839
The 0-51839 is an IRCA PC board from Reliance Electric. This component may have also been sold under the company names of Baldor Reliance or Asea Brown Boveri. Typically, the part number remains the same across company restructuring and so regardless of the name stamped on the board, the part should be compatible. Check your documentation to be sure.
The 0-51839 is a small rectangular-shaped circuit card designed with a conductive plug-in connector on its rear edge to allow the board to communicate with other components once it is installed within a rack system. It weighs approximately 0.75 pounds. The opposite short edge is configured with a front faceplate that is etched with the unit’s part number. This faceplate includes two set screws to hold the unit in place once it is installed within a rack. Additionally, the faceplate is built with a terminal strip for the addition of I/O along that is flanked by two standoffs. A safety plate is fitted to and above these standoffs to shield the terminal strip.
The circuit card itself is only sparsely populated with a few relays, resistors, and capacitors. The board uses some surface wiring to connect components. Components on this board are not typically marked with a reference designator, but the board includes a grid pattern to allow for component identification.
For additional information, please refer to the original documentation from Reliance or Asea Brown Boveri. Manuals and user guides will provide you with important information regarding proper maintenance and installation of this component. These documents should be reviewed before unboxing your purchase.
