Product Description
0-54339-4 Reliance Electric Memory Card
The 0-54339-4 from Reliance is a circuit board component manufactured for use within the company’s drive systems. Rarely, this board may have shipped marked as a component manufactured by Baldor Reliance or ABB. “54339-4” remains in the part ID in all cases.
The 0-54339-4 is a large rectangular board. Unlike many in this series, the circuit board does not have an attached faceplate. It does, however, have an extraction clip inserted into each of the leading board corners. Extraction clips give technicians a place to hold the circuit board, rather than handle delicate board edges and possibly damage components. They also offer a lever point to pull the circuit board from a tight rack location. The board is marked across its entire surface with a grid pattern. The rear surface carries several other codes beyond the board id. All corners are factory drilled.
The 0-54339-4 is populated by over sixty integrated circuits. A large bank of these is located in the bottom right quadrant. The board also uses transistors, resistors, resistor network arrays, capacitors, surface wiring, and diodes. The board has a single right-angled interface connector located on the top board edge. The board indents at the location of this component. The board has four narrow black components connected to its bottom edge. Each component is connected to the board using three screws.
More information regarding this board, its operation or installation, can be accessed through Reliance publications (manuals/data sheets/user guides.) These publications are a primary source of technical support information.
