About the 0-52711

0-52711 Reliance Programmable Data Input Card 115 VAC

The 0-52711 is a circuit board component manufactured by Reliance Electric for use within their various drive systems.  In some cases, this component may be marked as coming from ABB or from Baldor-Reliance. This relies on the year of the board’s manufacture due to mergers with those companies.   The part number will still include 52711.

The 0-52711 functions as a Programmable Data Input Card.  Unlike most cards in this series, it is not rectangular; rather, it is shaped like a rectangle with one long corner cut off.  This edge is populated by a black vertical component that houses two disk capacitors and four bipolar transistors. The board is cut through its surface above this black component in an extended oval to create a sort of handle at the top of the board.

The 0-52711 is marked on its surface by an open grid pattern.  This is marked by letters along one axis and by numbers along the other.  Numbers repeat about halfway down the board. Board components include one integrated circuit, twelve carbon composite resistors, eight diodes, and capacitors made from aluminum electrolytic material and ceramic material.  This includes two disk capacitors. The board has several instances of surface wiring. The integrated circuits is a high-performance analog bus driver.

The 0-52711 is marked on its back surface with codes like 800792-89A and 497.  The board is marked along its front edge with its product number and the notation of “115VAC.”   The board is drilled in two locations. More information regarding the operation or installation of the board may be found through Reliance publications like data sheets, manuals, or user guides.
