About the 0-51839-6
0-51839-6 IRCG Relay Card
The 0-51839-6 is a board component manufactured by Reliance Electric to fit into various drive systems. The board you are currently replacing may be marked with the manufacturer name of Baldor-Reliance, with Reliance Electric, or with ABB/Asea Brown Boveri, depending on the time of its manufacture. The part number is static.
The 0-51839-6 functions as a Relay Circuit Board. The PCB is fronted by a silver-colored faceplate with an opening that allows a cable with a single male plug to extend from the board. It also has seven red LED indicators located under a notation of “Relay On.” These indicators are individually numbered from one to seven. These LED indicators wire to the board using black and white wires. The front faceplate connects to the circuit board using three screw connections.
The 0-51839-6 is printed with a grid pattern marked off with letters and numbers on the two axes. The board is populated with seven relays. These are individually labeled as Relay pos. 1 through Relay pos. 7. Additionally, the board has a number of diodes and carbon composite resistors. It also has multiple stab-on connectors covered by plastic wire connectors. These connectors are marked on the board’s surface with the color of wire that should attach to it (orn/wht/blk/blu/red/grn.) The wires that terminate to these points are connected to the plug component previously mentioned.
The 0-51839-6 is marked with the board number and with the Reliance logo. The rear edge of the board extends into a ‘tail’ that has been covered with conductive tabs; this tail acts as a sort of backplane connector for the board. Refer to manuals or data sheets for more information. Reliance Electric was responsible for all technical support for this product.
