0-51839-4--Relay Board

The 0-51839-4 is a board component manufactured by Reliance Electric.  This PCB is no longer being manufactured and has been discontinued by Reliance. Your board may have originally been manufactured by this company when it was working under a different name.  It may be marked as manufactured by Baldor Reliance with a part number of 0518394 or from Asea Brown Bovari.  

The 0-51839-4 is a Relay Card.  The board is populated by seven relays that are placed in a V shape on the board.  Each relay is paired with a disk capacitor that is placed next to it. Each of these components is a dull orange color.  The board has metal film and carbon composite resistors. It also uses surface wiring to connect components located in the front faceplate to the PCB.  There is a long surface wire along the back edge. The rear edge of the board has a conductive tail that connects the board into the rack system.

The front faceplate of the 0-51839-4 has seven light components.  Each of these is numbered. The faceplate connects to the board via three screws connected through a flange.  There is also a blue connector mounted into the front faceplate. More information regarding the installation and operation of the board can be accessed through manuals, user guides, and data sheets originally published by Reliance.
